springboot集成swagger，并扫描多个包路径

一、引入依赖

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.5.0</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.5.0</version>
</dependency>

二、swagger类的编写

package com.autohome.fc.loan.dealer.provider.config;

import com.google.common.base.Function;
import com.google.common.base.Optional;
import com.google.common.base.Predicate;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.RequestHandler;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration   //让spring加载该类
@EnableSwagger2  //启动swagger
public class Swagger2 {

    @Bean
    public Docket createRestApi() {// 建立API基本信息
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("XX.provider.controller))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {// 建立API的基本信息，这些信息会在Swagger UI中进行显示
        return new ApiInfoBuilder()
                .title("xx")// API 标题
                .description("维护在springboot中的api")// API描述
                .contact("xx")// 联系人
                .version("1.0")// 版本号
                .build();
    }
}

三、接口响应实体对象

@ApiModel(value = "录单信息")
public class AccountInfoAPIDto {

    @ApiModelProperty(value = "录单人")
    private String inputBy;
    @ApiModelProperty(value = "录单人名称")
    private String inputName;
    @ApiModelProperty(value = "车商|合做网点编 码")
    private String dealerCode;
    @ApiModelProperty(value = "车商|合做网点名 称")
    private String dealerName;
    @ApiModelProperty(value = "代理人编码")
    private String agentCode;
    @ApiModelProperty(value = "代理人名称")
    private String agentName;

四、post请求接受参数

@ApiOperation(value = "信息录入接口")
@Override
public ResponseDto submitApply(@ApiParam @RequestBody SubmitApplyRequestDto submitApplyRequestDto) {
}

五、get请求接受参数

@ApiOperation(value="发送短信获取验证码")
@ApiImplicitParams({
        @ApiImplicitParam(name = "flowid", value = "流程号", required = true, paramType = "query", dataType = "String"),
        @ApiImplicitParam(name = "userId", value = "用户id", required = true, paramType = "query", dataType = "String")
})
@Override
public ResponseDto applyVerifyCode(String flowId,String userId) {
 
}

六、实现扫描多个包路径

@Configuration   //让spring加载该类
@EnableSwagger2  //启动swagger
public class Swagger2 {
    // 定义分隔符
    private static final String splitor = ";";

    @Bean
    public Docket createRestApi() {// 建立API基本信息
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(basePackage("XX.provider.controller"+splitor+"XX.provider.web.insurance"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {// 建立API的基本信息，这些信息会在Swagger UI中进行显示
        return new ApiInfoBuilder()
                .title("XX")// API 标题
                .description("XX")// API描述
                .contact("XX")// 联系人
                .version("1.0")// 版本号
                .build();
    }
    public static Predicate<RequestHandler> basePackage(final String basePackage) {
        return input -> declaringClass(input).transform(handlerPackage(basePackage)).or(true);
    }

    private static Function<Class<?>, Boolean> handlerPackage(final String basePackage)     {
        return input -> {
            // 循环判断匹配
            for (String strPackage : basePackage.split(splitor)) {
                boolean isMatch = input.getPackage().getName().startsWith(strPackage);
                if (isMatch) {
                    return true;
                }
            }
            return false;
        };
    }

    private static Optional<? extends Class<?>> declaringClass(RequestHandler input) {
        return Optional.fromNullable(input.declaringClass());
    }

}

七、完成上述代码添加上，启动Spring Boot程序，访问：http://localhost:8080/swagger-ui.html
