1、Swagger2是什么？

Swagger 是一款RESTFUL接口的文档在线自动生成+功能测试功能软件。
Swagger 是一个规范和完整的框架，用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。总体目标是使客户端和文件系统作为服务器以同样的速度来更新。文件的方法，参数和模型紧密集成到服务器端的代码，允许API来始终保持同步。Swagger 让部署管理和使用功能强大的API从未如此简单。

3.Swagger2的入门教程

3.1Swagger2的maven依赖

<!-- 构建Restful API --><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.4.0</version></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.4.0</version></dependency>

3.2RestApiConfig的配置

package com.lidong.dubbo.web.util;import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;/*** @项目名称:lidong-dubbo* @类名:RestApiConfig* @类的描述: Restapi的基本配置* @作者:lidong* @创建时间:2017/2/11 上午10:01* @公司:chni* @QQ:1561281670* @邮箱:lidong1665@163.com* @使用方法：Restful API 访问路径: http://localhost:8080/lidong-dubbo-web/swagger-ui.html*/
@EnableWebMvc
@EnableSwagger2
@Configuration
@ComponentScan(basePackages ="com.lidong.dubbo")
public class RestApiConfig extends WebMvcConfigurationSupport {@Beanpublic Docket createRestApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select().apis(RequestHandlerSelectors.basePackage("com.lidong.dubbo.web")).paths(PathSelectors.any()).build();}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("SpringMVC中使用Swagger2构建RESTful APIs").termsOfServiceUrl("https://github.com/lidong1665").contact(new Contact("请叫我小东子","http://blog.csdn.net/u010046908","lidong1665@163.com")).version("1.0.0").build();}}

3.3在Controller中添加

@ApiOperation(value = "获取用户详细信息", notes = "根据url的id来获取用户详细信息")@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long")@RequestMapping(value = "getUserForid/{id}", method = RequestMethod.GET)@ResponseBodypublic String getUser(@PathVariable int id) {try {return JsonUtil.bean2json(userService.getUserById(id));} catch (Exception e) {e.printStackTrace();}return null;}
