.addFilter(new JwtVerifyFileter(super.authenticationManager(),rsaKeyProperties))
.sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)//禁用session
;
}
}
8、启动类
package cn.**;
import cn.**.util.RsaKeyProperties;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
/**
* @ProjectName: springSecurity
* @Package: cn.cn.**
* @Author: huat
* @Date: 2019/12/21 8:38
* @Version: 1.0
*/
@SpringBootApplication
@EnableConfigurationProperties(RsaKeyProperties.class)//加载RsaKeyProperties类，以bean形式注入到spring容器中
public class SpringBootApplicationStart {
public static void main(String[] args) {
SpringApplication.run(SpringBootApplicationStart.class,args);
}
}
9、配置文件
spring:
datasource:
driver-class-name: com.mysql.jdbc.Driver
username: root
password: root
url: jdbc:mysql://localhost:3306/security?characterEncoding=UTF-8
mybatis:
type-aliases-package: cn.**.entity
logging:
level:
cn.**.dao: debug
rsa:
key:
#公钥保存地方
publicKeyFile: E:\test\public.pub
#私钥保存地方
privateKeyFile: E:\test\private
9、postman测试
请求完成后，能够看到返回的登录成功，点击Headersjava
将token复制，而后请求咱们的接口mysql
