一、添加Swagger2依赖

<dependency><!--添加Swagger依赖 -->
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.7.0</version>
</dependency>
<dependency><!--添加Swagger-UI依赖 -->
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.7.0</version>
</dependency>

二、添加配置

package com.xiaohang.springbootswagger2.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.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;/**
* 主要用途：开启在线接口文档和添加相关配置
*/@Configuration //标记配置类
@EnableSwagger2 //开启在线接口文档
public class Swagger2Config {
/**
* 添加摘要信息(Docket)
*/
@Bean
public Docket controllerApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(new ApiInfoBuilder()
.title("标题：jzh_用户信息管理系统_接口文档")
.description("描述：用于管理集团旗下公司的人员信息,具体包括XXX,XXX模块...")
.contact(new Contact("jzh", null, "191041707@qq.com"))
.version("版本号:1.0")
.build())
.select()
.apis(RequestHandlerSelectors.basePackage("com.xiaohang.springbootswagger2.controller"))
.paths(PathSelectors.any())
.build();
}
}

三、编写接口文档

  • @Api 描述类/接口的主要用途
  • @ApiOperation 描述方法用途
  • @ApiImplicitParam 描述方法的参数
  • @ApiImplicitParams 描述方法的参数(Multi-Params)
  • @ApiIgnore 忽略某类/方法/参数的文档

参考链接：http://blog.csdn.net/hj95815/article/details/78323766

Swagger2 使用注解来编写文档，只需要在控制层（controller）添加注解来描述接口信息即可。例如：

@Api("用户信息管理")
@RestController
@RequestMapping("/api/user/*")
public class UserController { @Autowired
private UserService userService; @ApiOperation("获取用户列表")
@GetMapping("list")
public List userList() {
return userService.list();
} @ApiOperation("获取单个用户")
@ApiImplicitParam(paramType="query",name = "userId", value = "单个用户Id", dataType = "String")
@GetMapping("list/{userId}")
public User getOne(@RequestParam String userId){
return userService.getOne(userId);
} @ApiOperation("存储单个用户")
@ApiImplicitParam(name = "user", value = "单个用户信息", dataType = "json")
@PostMapping(value = "save")
public String save(@RequestBody User user) {
if (userService.save(user))
return user.toString();
return "{\"msg\":\"error\"}";
} @ApiOperation("更新单个用户")
@ApiImplicitParam(name = "user", value = "单个用户信息", dataType = "json")
@PutMapping("update")
public String update(@RequestBody User user) {
if(userService.update(user))
return user.toString();
return "{\"msg\":\"error\"}";
} @ApiOperation("删除单个用户")
@ApiImplicitParam(paramType="query",name = "userId", value = "单个用户Id", dataType = "String")
@DeleteMapping("delete/{userId}")
public String delete(@RequestParam String userId) {
if (userService.delete(userId))
return "{\"msg\":\"success\"}";
return "{\"msg\":\"error\"}";
}
}

四、汉化(可跳过)

1、添加自定义页面

在resourece目录下创建\META-INF\resourece目录，然后创建一个名称为"swagger-ui.html" 的HTML文件。

内容如下：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Swagger UI</title>
<link rel="icon" type="image/png" href="webjars/springfox-swagger-ui/images/favicon-32x32.png" sizes="32x32"/>
<link rel="icon" type="image/png" href="webjars/springfox-swagger-ui/images/favicon-16x16.png" sizes="16x16"/>
<link href='webjars/springfox-swagger-ui/css/typography.css' media='screen' rel='stylesheet' type='text/css'/>
<link href='webjars/springfox-swagger-ui/css/reset.css' media='screen' rel='stylesheet' type='text/css'/>
<link href='webjars/springfox-swagger-ui/css/screen.css' media='screen' rel='stylesheet' type='text/css'/>
<link href='webjars/springfox-swagger-ui/css/reset.css' media='print' rel='stylesheet' type='text/css'/>
<link href='webjars/springfox-swagger-ui/css/print.css' media='print' rel='stylesheet' type='text/css'/> <script src='webjars/springfox-swagger-ui/lib/object-assign-pollyfill.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/jquery-1.8.0.min.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/jquery.slideto.min.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/jquery.wiggle.min.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/jquery.ba-bbq.min.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/handlebars-4.0.5.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/lodash.min.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/backbone-min.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/swagger-ui.min.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/highlight.9.1.0.pack.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/highlight.9.1.0.pack_extended.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/jsoneditor.min.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/marked.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lib/swagger-oauth.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/springfox.js' type='text/javascript'></script> <!--国际化操作：选择中文版 -->
<script src='webjars/springfox-swagger-ui/lang/translator.js' type='text/javascript'></script>
<script src='webjars/springfox-swagger-ui/lang/zh-cn.js' type='text/javascript'></script></head><body class="swagger-section">
<div id='header'>
<div class="swagger-ui-wrap">
<a id="logo" href="http://swagger.io">![](webjars/springfox-swagger-ui/images/logo_small.png)<span class="logo__title">swagger</span></a>
<form id='api_selector'>
<div class='input'>
<select id="select_baseUrl" name="select_baseUrl"></select>
</div>
<div class='input'><input placeholder="http://example.com/api" id="input_baseUrl" name="baseUrl" type="text"/></div>
<div id='auth_container'></div>
<div class='input'><a id="explore" class="header__btn" href="#" data-sw-translate>Explore</a></div>
</form>
</div>
</div><div id="message-bar" class="swagger-ui-wrap" data-sw-translate> </div>
<div id="swagger-ui-container" class="swagger-ui-wrap"></div>
</body>
</html>

2、添加配置

package com.xiaohang.springbootswagger2.config;import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;@Configuration
class WebMvcConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/"); registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}}

3、在启动类上添加注解@EnableWebMvc

五、查阅接口文档

打开http://localhost:8080/swagger-ui.html

效果如下：

六、测试接口
