一简介

License，即版权许可证，通常用于收费软件给付费用户提供的访问许可证实。根据应用部署位置的不一样，通常能够分为如下两种状况讨论：css

应用部署在开发者本身的云服务器上。这种状况下用户经过帐号登陆的形式远程访问，所以只须要在帐号登陆的时候校验目标帐号的有效期、访问权限等信息便可。
应用部署在客户的内网环境。由于这种状况开发者没法控制客户的网络环境，也不能保证应用所在服务器能够访问外网，所以一般的作法是使用服务器许可文件，在应用启动的时候加载证书，而后在登陆或者其余关键操做的地方校验证书的有效性。

注：限于文章篇幅，这里只讨论代码层面的许可限制，暂不考虑逆向破解等问题。此外，在下面我只讲解关键代码实现，完整代码能够参考：gitee.com/zifangsky/L…html

二使用 TrueLicense 生成License

（1）使用Spring Boot构建测试项目ServerDemo，用于为客户生成License许可文件：

注：这个完整的Demo项目能够参考：gitee.com/zifangsky/L…java

i）在pom.xml中添加关键依赖：jquery

<dependency>
    <groupId>de.schlichtherle.truelicense</groupId>
    <artifactId>truelicense-core</artifactId>
    <version>1.33</version>
    <scope>provided</scope>
</dependency>
复制代码

ii）校验自定义的License参数：linux

TrueLicense的 de.schlichtherle.license.LicenseManager 类自带的verify方法只校验了咱们后面颁发的许可文件的生效和过时时间，然而在实际项目中咱们可能须要额外校验应用部署的服务器的IP地址、MAC地址、CPU序列号、主板序列号等信息，所以咱们须要复写框架的部分方法以实现校验自定义参数的目的。git

首先须要添加一个自定义的可被容许的服务器硬件信息的实体类（若是校验其余参数，可自行补充）：web

package cn.zifangsky.license;

import java.io.Serializable;
import java.util.List;

/** * 自定义须要校验的License参数 * * @author zifangsky * @date 2018/4/23 * @since 1.0.0 */
public class LicenseCheckModel implements Serializable{

    private static final long serialVersionUID = 8600137500316662317L;
    /** * 可被容许的IP地址 */
    private List<String> ipAddress;

    /** * 可被容许的MAC地址 */
    private List<String> macAddress;

    /** * 可被容许的CPU序列号 */
    private String cpuSerial;

    /** * 可被容许的主板序列号 */
    private String mainBoardSerial;

    //省略setter和getter方法

    @Override
    public String toString() {
        return "LicenseCheckModel{" +
                "ipAddress=" + ipAddress +
                ", macAddress=" + macAddress +
                ", cpuSerial='" + cpuSerial + '\'' +
                ", mainBoardSerial='" + mainBoardSerial + '\'' +
                '}';
    }
}
复制代码

其次，添加一个License生成类须要的参数：ajax

package cn.zifangsky.license;

import com.fasterxml.jackson.annotation.JsonFormat;

import java.io.Serializable;
import java.util.Date;

/** * License生成类须要的参数 * * @author zifangsky * @date 2018/4/19 * @since 1.0.0 */
public class LicenseCreatorParam implements Serializable {

    private static final long serialVersionUID = -7793154252684580872L;
    /** * 证书subject */
    private String subject;

    /** * 密钥别称 */
    private String privateAlias;

    /** * 密钥密码（须要妥善保管，不能让使用者知道） */
    private String keyPass;

    /** * 访问秘钥库的密码 */
    private String storePass;

    /** * 证书生成路径 */
    private String licensePath;

    /** * 密钥库存储路径 */
    private String privateKeysStorePath;

    /** * 证书生效时间 */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date issuedTime = new Date();

    /** * 证书失效时间 */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8")
    private Date expiryTime;

    /** * 用户类型 */
    private String consumerType = "user";

    /** * 用户数量 */
    private Integer consumerAmount = 1;

    /** * 描述信息 */
    private String description = "";

    /** * 额外的服务器硬件校验信息 */
    private LicenseCheckModel licenseCheckModel;

    //省略setter和getter方法

    @Override
    public String toString() {
        return "LicenseCreatorParam{" +
                "subject='" + subject + '\'' +
                ", privateAlias='" + privateAlias + '\'' +
                ", keyPass='" + keyPass + '\'' +
                ", storePass='" + storePass + '\'' +
                ", licensePath='" + licensePath + '\'' +
                ", privateKeysStorePath='" + privateKeysStorePath + '\'' +
                ", issuedTime=" + issuedTime +
                ", expiryTime=" + expiryTime +
                ", consumerType='" + consumerType + '\'' +
                ", consumerAmount=" + consumerAmount +
                ", description='" + description + '\'' +
                ", licenseCheckModel=" + licenseCheckModel +
                '}';
    }
}

                    decoder.close();
                }
                if(inputStream != null){
                    inputStream.close();
                }
            } catch (Exception e) {
                logger.error("XMLDecoder解析XML失败",e);
            }
        }

        return null;
    }

    /** * 获取当前服务器须要额外校验的License参数 * @author zifangsky * @date 2018/4/23 14:33 * @since 1.0.0 * @return demo.LicenseCheckModel */
    private LicenseCheckModel getServerInfos(){
        //操做系统类型
        String osName = System.getProperty("os.name").toLowerCase();
        AbstractServerInfos abstractServerInfos = null;

        if (osName.startsWith("windows")) {
            abstractServerInfos = new WindowsServerInfos();
        } else if (osName.startsWith("linux")) {
            abstractServerInfos = new LinuxServerInfos();
        }else{//其余服务器类型
            abstractServerInfos = new LinuxServerInfos();
        }

        return abstractServerInfos.getServerInfos();
    }

    /** * 校验当前服务器的IP/Mac地址是否在可被容许的IP范围内<br/> * 若是存在IP在可被容许的IP/Mac地址范围内，则返回true * @author zifangsky * @date 2018/4/24 11:44 * @since 1.0.0 * @return boolean */
    private boolean checkIpAddress(List<String> expectedList,List<String> serverList){
        if(expectedList != null && expectedList.size() > 0){
            if(serverList != null && serverList.size() > 0){

            return true;
        }
    }

    /** * 校验当前服务器硬件（主板、CPU等）序列号是否在可容许范围内 * @author zifangsky * @date 2018/4/24 14:38 * @since 1.0.0 * @return boolean */
    private boolean checkSerial(String expectedSerial,String serverSerial){
        if(StringUtils.isNotBlank(expectedSerial)){
            if(StringUtils.isNotBlank(serverSerial)){
                if(expectedSerial.equals(serverSerial)){
                    return true;
                }
            }

            return false;
        }else{
            return true;
        }
    }

}
复制代码

最后是License生成类，用于生成License证书：

package cn.zifangsky.license;

import de.schlichtherle.license.CipherParam;
import de.schlichtherle.license.DefaultCipherParam;
import de.schlichtherle.license.DefaultLicenseParam;
import de.schlichtherle.license.KeyStoreParam;
import de.schlichtherle.license.LicenseContent;
import de.schlichtherle.license.LicenseManager;
import de.schlichtherle.license.LicenseParam;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

import javax.security.auth.x500.X500Principal;
import java.io.File;
import java.text.MessageFormat;
import java.util.prefs.Preferences;

/** * License生成类 * * @author zifangsky * @date 2018/4/19 * @since 1.0.0 */
public class LicenseCreator {
    private static Logger logger = LogManager.getLogger(LicenseCreator.class);
    private final static X500Principal DEFAULT_HOLDER_AND_ISSUER = new X500Principal("CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN");
    private LicenseCreatorParam param;

    public LicenseCreator(LicenseCreatorParam param) {
        this.param = param;
    }

    /** * 生成License证书 * @author zifangsky * @date 2018/4/20 10:58 * @since 1.0.0 * @return boolean */
    public boolean generateLicense(){
        try {
            LicenseManager licenseManager = new CustomLicenseManager(initLicenseParam());
            LicenseContent licenseContent = initLicenseContent();

            licenseManager.store(licenseContent,new File(param.getLicensePath()));

            return true;
        }catch (Exception e){
            logger.error(MessageFormat.format("证书生成失败：{0}",param),e);
            return false;
        }
    }

    /** * 初始化证书生成参数 * @author zifangsky * @date 2018/4/20 10:56 * @since 1.0.0 * @return de.schlichtherle.license.LicenseParam */
    private LicenseParam initLicenseParam(){
        Preferences preferences = Preferences.userNodeForPackage(LicenseCreator.class);

        //设置对证书内容加密的秘钥
        CipherParam cipherParam = new DefaultCipherParam(param.getStorePass());

        KeyStoreParam privateStoreParam = new CustomKeyStoreParam(LicenseCreator.class
                ,param.getPrivateKeysStorePath()
                ,param.getPrivateAlias()
                ,param.getStorePass()
                ,param.getKeyPass());

        LicenseParam licenseParam = new DefaultLicenseParam(param.getSubject()
                ,preferences
                ,privateStoreParam
                ,cipherParam);

        return licenseParam;
    }

    /** * 设置证书生成正文信息 * @author zifangsky * @date 2018/4/20 10:57 * @since 1.0.0 * @return de.schlichtherle.license.LicenseContent */
    private LicenseContent initLicenseContent(){
        LicenseContent licenseContent = new LicenseContent();
        licenseContent.setHolder(DEFAULT_HOLDER_AND_ISSUER);
        licenseContent.setIssuer(DEFAULT_HOLDER_AND_ISSUER);

        licenseContent.setSubject(param.getSubject());
        licenseContent.setIssued(param.getIssuedTime());
        licenseContent.setNotBefore(param.getIssuedTime());
        licenseContent.setNotAfter(param.getExpiryTime());
        licenseContent.setConsumerType(param.getConsumerType());
        licenseContent.setConsumerAmount(param.getConsumerAmount());
        licenseContent.setInfo(param.getDescription());

        //扩展校验服务器硬件信息
        licenseContent.setExtra(param.getLicenseCheckModel());

        return licenseContent;
    }

}
复制代码

iii）添加一个生成证书的Controller：

这个Controller对外提供了两个RESTful接口，分别是「获取服务器硬件信息」和「生成证书」，示例代码以下：

package cn.zifangsky.controller;

import cn.zifangsky.license.AbstractServerInfos;
import cn.zifangsky.license.LicenseCheckModel;
import cn.zifangsky.license.LicenseCreator;
import cn.zifangsky.license.LicenseCreatorParam;
import cn.zifangsky.license.LinuxServerInfos;
import cn.zifangsky.license.WindowsServerInfos;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;

/** * * 用于生成证书文件，不能放在给客户部署的代码里 * @author zifangsky * @date 2018/4/26 * @since 1.0.0 */
@RestController
@RequestMapping("/license")
public class LicenseCreatorController {

    /** * 证书生成路径 */
    @Value("${license.licensePath}")
    private String licensePath;

    /** * 获取服务器硬件信息 * @author zifangsky * @date 2018/4/26 13:13 * @since 1.0.0 * @param osName 操做系统类型，若是为空则自动判断 * @return com.ccx.models.license.LicenseCheckModel */
    @RequestMapping(value = "/getServerInfos",produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
    public LicenseCheckModel getServerInfos(@RequestParam(value = "osName",required = false) String osName) {
        //操做系统类型
        if(StringUtils.isBlank(osName)){
            osName = System.getProperty("os.name");
        }
        osName = osName.toLowerCase();

        AbstractServerInfos abstractServerInfos = null;

        //根据不一样操做系统类型选择不一样的数据获取方法
        if (osName.startsWith("windows")) {
            abstractServerInfos = new WindowsServerInfos();
        } else if (osName.startsWith("linux")) {
            abstractServerInfos = new LinuxServerInfos();
        }else{//其余服务器类型
            abstractServerInfos = new LinuxServerInfos();
        }

        return abstractServerInfos.getServerInfos();
    }

    /** * 生成证书 * @author zifangsky * @date 2018/4/26 13:13 * @since 1.0.0 * @param param 生成证书须要的参数，如：{"subject":"ccx-models","privateAlias":"privateKey","keyPass":"5T7Zz5Y0dJFcqTxvzkH5LDGJJSGMzQ","storePass":"3538cef8e7","licensePath":"C:/Users/zifangsky/Desktop/license.lic","privateKeysStorePath":"C:/Users/zifangsky/Desktop/privateKeys.keystore","issuedTime":"2018-04-26 14:48:12","expiryTime":"2018-12-31 00:00:00","consumerType":"User","consumerAmount":1,"description":"这是证书描述信息","licenseCheckModel":{"ipAddress":["192.168.245.1","10.0.5.22"],"macAddress":["00-50-56-C0-00-01","50-7B-9D-F9-18-41"],"cpuSerial":"BFEBFBFF000406E3","mainBoardSerial":"L1HF65E00X9"}} * @return java.util.Map<java.lang.String,java.lang.Object> */
    @RequestMapping(value = "/generateLicense",produces = {MediaType.APPLICATION_JSON_UTF8_VALUE})
    public Map<String,Object> generateLicense(@RequestBody(required = true) LicenseCreatorParam param) {
        Map<String,Object> resultMap = new HashMap<>(2);

        if(StringUtils.isBlank(param.getLicensePath())){
            param.setLicensePath(licensePath);
        }

        LicenseCreator licenseCreator = new LicenseCreator(param);
        boolean result = licenseCreator.generateLicense();

        if(result){
            resultMap.put("result","ok");
            resultMap.put("msg",param);
        }else{
            resultMap.put("result","error");
            resultMap.put("msg","证书文件生成失败！");
        }

        return resultMap;
    }

}
复制代码

（2）使用JDK自带的 keytool 工具生成公私钥证书库：

假如咱们设置公钥库密码为：public_password1234，私钥库密码为：private_password1234，则生成命令以下：

#生成命令
keytool -genkeypair -keysize 1024 -validity 3650 -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -keypass "private_password1234" -dname "CN=localhost, OU=localhost, O=localhost, L=SH, ST=SH, C=CN"

#导出命令
keytool -exportcert -alias "privateKey" -keystore "privateKeys.keystore" -storepass "public_password1234" -file "certfile.cer"

#导入命令
keytool -import -alias "publicCert" -file "certfile.cer" -keystore "publicCerts.keystore" -storepass "public_password1234"
复制代码

上述命令执行完成以后，会在当前路径下生成三个文件，分别是：privateKeys.keystore、publicCerts.keystore、certfile.cer。其中文件certfile.cer再也不须要能够删除，文件privateKeys.keystore用于当前的 ServerDemo 项目给客户生成license文件，而文件publicCerts.keystore则随应用代码部署到客户服务器，用户解密license文件并校验其许可信息。

（3）为客户生成license文件：

将 ServerDemo 项目部署到客户服务器，经过如下接口获取服务器的硬件信息（等license文件生成后须要删除这个项目。固然也能够经过命令手动获取客户服务器的硬件信息，而后在开发者本身的电脑上生成license文件）：

注：上图使用的是Firefox的RESTClient插件

而后生成license文件：

请求时须要在Header中添加一个Content-Type，其值为：application/json;charset=UTF-8。参数示例以下：

{
	"subject": "license_demo",
	"privateAlias": "privateKey",
	"keyPass": "private_password1234",
	"storePass": "public_password1234",
	"licensePath": "C:/Users/zifangsky/Desktop/license_demo/license.lic",
	"privateKeysStorePath": "C:/Users/zifangsky/Desktop/license_demo/privateKeys.keystore",
	"issuedTime": "2018-07-10 00:00:01",
	"expiryTime": "2019-12-31 23:59:59",
	"consumerType": "User",
	"consumerAmount": 1,
	"description": "这是证书描述信息",
	"licenseCheckModel": {
		"ipAddress": ["192.168.245.1", "10.0.5.22"],
		"macAddress": ["00-50-56-C0-00-01", "50-7B-9D-F9-18-41"],
		"cpuSerial": "BFEBFBFF000406E3",
		"mainBoardSerial": "L1HF65E00X9"
	}
}
复制代码

若是请求成功，那么最后会在 licensePath 参数设置的路径生成一个license.lic的文件，这个文件就是给客户部署代码的服务器许可文件。

三给客户部署的应用中添加License校验

（1）使用Spring Boot构建测试项目ServerDemo，用于模拟给客户部署的应用：

注：这个完整的Demo项目能够参考：gitee.com/zifangsky/L…

（2）添加License校验类须要的参数：

package cn.zifangsky.license;

/** * License校验类须要的参数 * * @author zifangsky * @date 2018/4/20 * @since 1.0.0 */
public class LicenseVerifyParam {

    /** * 证书subject */
    private String subject;

    /** * 公钥别称 */
    private String publicAlias;

    /** * 访问公钥库的密码 */
    private String storePass;

    /** * 证书生成路径 */
    private String licensePath;

    /** * 密钥库存储路径 */
    private String publicKeysStorePath;

    public LicenseVerifyParam() {

    }

    public LicenseVerifyParam(String subject, String publicAlias, String storePass, String licensePath, String publicKeysStorePath) {
        this.subject = subject;
        this.publicAlias = publicAlias;
        this.storePass = storePass;
        this.licensePath = licensePath;
        this.publicKeysStorePath = publicKeysStorePath;
    }

    //省略setter和getter方法

    @Override
    public String toString() {
        return "LicenseVerifyParam{" +
                "subject='" + subject + '\'' +
                ", publicAlias='" + publicAlias + '\'' +
                ", storePass='" + storePass + '\'' +
                ", licensePath='" + licensePath + '\'' +
                ", publicKeysStorePath='" + publicKeysStorePath + '\'' +
                '}';
    }
}
复制代码

而后再添加License校验类：

package cn.zifangsky.license;

import de.schlichtherle.license.*;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;

import java.io.File;
import java.text.DateFormat;
import java.text.MessageFormat;
import java.text.SimpleDateFormat;
import java.util.prefs.Preferences;

/** * License校验类 * * @author zifangsky * @date 2018/4/20 * @since 1.0.0 */
public class LicenseVerify {
    private static Logger logger = LogManager.getLogger(LicenseVerify.class);

    /** * 安装License证书 * @author zifangsky * @date 2018/4/20 16:26 * @since 1.0.0 */
    public synchronized LicenseContent install(LicenseVerifyParam param){
        LicenseContent result = null;
        DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        //1. 安装证书
        try{
            LicenseManager licenseManager = LicenseManagerHolder.getInstance(initLicenseParam(param));
            licenseManager.uninstall();

            result = licenseManager.install(new File(param.getLicensePath()));
            logger.info(MessageFormat.format("证书安装成功，证书有效期：{0} - {1}",format.format(result.getNotBefore()),format.format(result.getNotAfter())));
        }catch (Exception e){
            logger.error("证书安装失败！",e);
        }

        return result;
    }

    /** * 校验License证书 * @author zifangsky * @date 2018/4/20 16:26 * @since 1.0.0 * @return boolean */
    public boolean verify(){
        LicenseManager licenseManager = LicenseManagerHolder.getInstance(null);
        DateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

        //2. 校验证书
        try {
            LicenseContent licenseContent = licenseManager.verify();
// System.out.println(licenseContent.getSubject());

            logger.info(MessageFormat.format("证书校验经过，证书有效期：{0} - {1}",format.format(licenseContent.getNotBefore()),format.format(licenseContent.getNotAfter())));
            return true;
        }catch (Exception e){
            logger.error("证书校验失败！",e);
            return false;
        }
    }

    /** * 初始化证书生成参数 * @author zifangsky * @date 2018/4/20 10:56 * @since 1.0.0 * @param param License校验类须要的参数 * @return de.schlichtherle.license.LicenseParam */
    private LicenseParam initLicenseParam(LicenseVerifyParam param){
        Preferences preferences = Preferences.userNodeForPackage(LicenseVerify.class);

        CipherParam cipherParam = new DefaultCipherParam(param.getStorePass());

        KeyStoreParam publicStoreParam = new CustomKeyStoreParam(LicenseVerify.class
                ,param.getPublicKeysStorePath()
                ,param.getPublicAlias()
                ,param.getStorePass()
                ,null);

        return new DefaultLicenseParam(param.getSubject()
                ,preferences
                ,publicStoreParam
                ,cipherParam);
    }

}
复制代码

（3）添加Listener，用于在项目启动的时候安装License证书：

package cn.zifangsky.license;

import org.apache.commons.lang3.StringUtils;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.stereotype.Component;

/** * 在项目启动时安装证书 * * @author zifangsky * @date 2018/4/24 * @since 1.0.0 */
@Component
public class LicenseCheckListener implements ApplicationListener<ContextRefreshedEvent> {
    private static Logger logger = LogManager.getLogger(LicenseCheckListener.class);

    /** * 证书subject */
    @Value("${license.subject}")
    private String subject;

    /** * 公钥别称 */
    @Value("${license.publicAlias}")
    private String publicAlias;

    /** * 访问公钥库的密码 */
    @Value("${license.storePass}")
    private String storePass;

    /** * 证书生成路径 */
    @Value("${license.licensePath}")
    private String licensePath;

    /** * 密钥库存储路径 */
    @Value("${license.publicKeysStorePath}")
    private String publicKeysStorePath;

    @Override
    public void onApplicationEvent(ContextRefreshedEvent event) {
        //root application context 没有parent
        ApplicationContext context = event.getApplicationContext().getParent();
        if(context == null){
            if(StringUtils.isNotBlank(licensePath)){
                logger.info("++++++++ 开始安装证书 ++++++++");

                LicenseVerifyParam param = new LicenseVerifyParam();
                param.setSubject(subject);
                param.setPublicAlias(publicAlias);
                param.setStorePass(storePass);
                param.setLicensePath(licensePath);
                param.setPublicKeysStorePath(publicKeysStorePath);

                LicenseVerify licenseVerify = new LicenseVerify();
                //安装证书
                licenseVerify.install(param);

                logger.info("++++++++ 证书安装结束 ++++++++");
            }
        }
    }
}
复制代码

注：上面代码使用参数信息以下所示：

#License相关配置
license.subject=license_demo
license.publicAlias=publicCert
license.storePass=public_password1234
license.licensePath=C:/Users/zifangsky/Desktop/license_demo/license.lic
license.publicKeysStorePath=C:/Users/zifangsky/Desktop/license_demo/publicCerts.keystore
复制代码

（4）添加拦截器，用于在登陆的时候校验License证书：

package cn.zifangsky.license;

import com.alibaba.fastjson.JSON;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.web.servlet.handler.HandlerInterceptorAdapter;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;

/** * LicenseCheckInterceptor * * @author zifangsky * @date 2018/4/25 * @since 1.0.0 */
public class LicenseCheckInterceptor extends HandlerInterceptorAdapter{
    private static Logger logger = LogManager.getLogger(LicenseCheckInterceptor.class);

    @Override
    public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
        LicenseVerify licenseVerify = new LicenseVerify();

        //校验证书是否有效
        boolean verifyResult = licenseVerify.verify();

        if(verifyResult){
            return true;
        }else{
            response.setCharacterEncoding("utf-8");
            Map<String,String> result = new HashMap<>(1);
            result.put("result","您的证书无效，请核查服务器是否取得受权或从新申请证书！");

            response.getWriter().write(JSON.toJSONString(result));

            return false;
        }
    }

}
复制代码

（5）添加登陆页面并测试：

添加一个登陆页面，能够在license校验失败的时候给出错误提示：

<html xmlns:th="http://www.thymeleaf.org">
<head>
    <meta content="text/html;charset=UTF-8"/>
    <meta http-equiv="X-UA-Compatible" content="IE=edge"/>
    <meta name="viewport" content="width=device-width, initial-scale=1"/>
    <title>登陆页面</title>
