pom.xml添加Swagger2依赖

    <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.2.2</version>
        </dependency>

创建Swagger2配置类

package com.springbootweb.common.config.swagger2;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger2 {

  @Bean
  public Docket createRestApi() {
    return new Docket(DocumentationType.SWAGGER_2)
            .apiInfo(apiInfo())
            .select()
            .apis(RequestHandlerSelectors.basePackage("com.springbootweb.modules.system.controller"))
            .paths(PathSelectors.any())
            .build();
  }

  private ApiInfo apiInfo() {
    return new ApiInfoBuilder()
            .title("maven构建Spring boot项目")
            .description("maven构建Spring boot项目 集成mybatis使用pagehelper插件 ，实现热部署 by 陈晨")
            .termsOfServiceUrl("http://blog.csdn.net/chen1218chen")
            .contact("chenchen")
            .version("1.0")
            .build();
  }

}

controller

rest接口上添加 @ApiOperation标签，即可生成对应的接口文档，文档更详细的配置请查看swagger2 api

package com.springbootweb.modules.system.controller;

@RestController

    @GetMapping("/test")

        return name;
    }

    @GetMapping("/test1")

    }
    
    
    @ApiOperation(value="登陆", notes="登陆")
    @PostMapping("/login")
    public SysResponse login(@RequestParam String username, String password) {
        Subject subject = SecurityUtils.getSubject();
        if (!subject.isAuthenticated()) {
            return SysResponse.fail("登录失败，用户名或密码不正确！");
        }
        String principal = (String) subject.getPrincipal();
        if (username.equals(principal)) {//同一用户登录
            return SysResponse.ok("登录成功");
        }
        subject.logout();//否则,原用户退出登录，新用户登录
        try {
            subject.login(new UsernamePasswordToken(username, password));
            return SysResponse.ok("登录成功");
        } catch (AuthenticationException e) {
            e.printStackTrace();
            return SysResponse.fail("登录失败，用户名或密码不正确！");
        }
    }

    @ApiOperation(value="退出", notes="退出")
    @GetMapping("/logout")
    public boolean logout() {
        Subject subject = SecurityUtils.getSubject();
        if (subject.isAuthenticated()) {
            subject.logout();
        }
        return true;
    }

    @GetMapping("/unAuthenticated")
    public SysResponse unAuthenticated() {
        return SysResponse.fail("Haven't logined");
    }
    
    @ApiOperation(value="获取当前登陆用户", notes="获取当前登陆用户")
    @GetMapping("/getCurrentUser")
    public User getCurrentUser() {
        Subject subject = SecurityUtils.getSubject();
        if (!subject.isAuthenticated()) {
            return null;
        }
        String username = (String) subject.getPrincipal();
        return userService.getUserByName(username);
    }

    @GetMapping("/port")
    public String port() {
        return port;
    }

}

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