Spring Boot项目中使用Swagger2

　　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";
    }
}
