**Swagger2是一款restful接口文档在线生成和在线接口调试工具，Swagger2在Swagger1.x版本的基础上做了些改进，下面是在一个Spring Boot项目中引入Swagger2的简要示例。**

**一、在pom.xml添加如下maven依赖**

<dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.7.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.7.0</version>
    </dependency>

**二、Swagger配置类**

package com.weidai.zm.zyq.config;
    
    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;
    
    /**
     * @author : zhangyanqing
     * @time : 2017/11/8
     * @desc : Swagger2配置
     */
    @Configuration
    @EnableSwagger2
    public class SwaggerConfig {
        @Bean
        public Docket createRestApi(){
            return new Docket(DocumentationType.SWAGGER_2)
                    .apiInfo(apiInfo())
                    .select()
                    .apis(RequestHandlerSelectors.basePackage("com.weidai.zm.zyq.action"))
                    .paths(PathSelectors.any())
                    .build();
        }
    
        private ApiInfo apiInfo(){
            return new ApiInfoBuilder().title("Spring Boot中使用Swagger构建Rest Api")
                    .version("1.0").build();
        }
    }

**三、SpringBoot启动类修改**

package com.weidai.zm.zyq;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    @SpringBootApplication
    public class SwaggerDemoApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(SwaggerDemoApplication.class, args);
        }
    }

**四、接口注释示例**

package com.weidai.zm.zyq.action;
    
    import com.weidai.zm.zyq.domain.User;
    import io.swagger.annotations.Api;
    import io.swagger.annotations.ApiImplicitParam;
    import io.swagger.annotations.ApiOperation;
    import io.swagger.annotations.ApiParam;
    import org.springframework.web.bind.annotation.*;
    
    /**
     * @author : zhangyanqing
     * @time : 2017/11/8
     * @desc : ${DESCRIPTION}
     */
    @Api(value="/test", tags="测试接口模块")
    @RestController
    @RequestMapping("/test")
    public class TestController {
        @ApiOperation(value="展示首页信息", notes = "展示首页信息")
        @GetMapping("/show")
        public Object showInfo(){
            return "hello world";
        }
    
        @ApiOperation(value="添加用户信息", notes = "添加用户信息")
        @ApiImplicitParam(name="user", value="User", required = true, dataType = "User")
        @PostMapping("/addUser")
        public Object addUser(@RequestBody User user){
            return "success";
        }
    }
