序言:编写和维护接口文档是每个程序员的职责,根据Swagger2可以快速帮助我们编写最新的API接口文档,再也不用担心开会前仍忙于整理各种资料了,间接提升了团队开发的沟通效率。此外,本教程还额外提供了UI汉化教程,去除阅读官方英文界面的烦恼。(目前Swagger汉化教程是找不到的,因为官方手册实在写得太烂。。)
SpringBoot + Swagger2 UI界面-汉化教程
1.默认的英文界面UI
想必很多小伙伴都曾经使用过Swagger,但是打开UI界面之后,却是下面这样的画风,纯英文的界面并不太友好,作为国人还是习惯中文界面。
号称世界最流行的API工具总不该不支持国际化属性吧,楼主在官方使用手册找到关于本地化和翻译的说明:
也就是说,只要添加翻译器和对于的译文JS就可以显示中文界面了。(使用IDEA 双击Shift 快速找到swagger-ui.html 入口文件)
注:对静态资源的存放路径有疑惑的请戳:SpringBoot项目结构说明
2.定制中文界面
2.1 添加首页和译文
重点来了,在src/main/resources
目录下创建META-INF\resources
目录,然后创建一个名称为"swagger-ui.html" 的HTML文件。如图:
注意文件名不要起错,接下来将下面这段内容原封不动的拷贝进去。
<!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/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/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>
OK 大功告成 我们访问 http://localhost:8080/swagger-ui.html 看看显示效果:
注:关于国际化,直接在Github下载好Swagger-UI的源码,将swagger-ui.html替换成上文,直接发布到Maven私服仓库,使用效果更佳。
2.2 更详细的译文翻译(非必需)
如果想进一步调整译文,可以在META-INF\resources\webjars\springfox-swagger-ui\lang 目录下添加zh-cn.js文件.
然后在译文(zh-cn.js )根据个人喜好来添加翻译内容,如下
'use strict';
/* jshint quotmark: double */
window.SwaggerTranslator.learn({
"Warning: Deprecated":"警告:已过时",
"Implementation Notes":"实现备注",
"Response Class":"响应类",
"Status":"状态",
"Parameters":"参数",

});
===========接下来,正式进入Swagger2的使用教程===========
SpringBoot + Swagger2 使用教程
1. 引入依赖
<!--依赖管理 -->
<dependencies>
<dependency> <!--添加Web依赖 -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<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>
<dependency> <!--添加热部署依赖 -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
</dependency>
<dependency><!--添加Test依赖 -->
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
2. 添加配置
@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:某公司_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("一只袜子", null, null))
.version("版本号:1.0")
.build())
.select()
.apis(RequestHandlerSelectors.basePackage("com.hehe.controller"))
.paths(PathSelectors.any())
.build();
}
}
3. 编写接口文档
Swagger2 基本使用:
- @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
Swagger2 使用注解来编写文档:
Swagger2编写接口文档相当简单,只需要在控制层(Controller)添加注解来描述接口信息即可。例如:
package com.hehe.controller;
@Api("用户信息管理")
@RestController
@RequestMapping("/user/*")
public class UserController {
private final static List<User> userList = new ArrayList<>();
{
userList.add(new User("1", "admin", "123456"));
userList.add(new User("2", "jacks", "111111"));
}
@ApiOperation("获取列表")
@GetMapping("list")
public List userList() {
return userList;
}
@ApiOperation("新增用户")
@PostMapping("save")
public boolean save(User user) {
return userList.add(user);
}
@ApiOperation("更新用户")
@ApiImplicitParam(name = "user", value = "单个用户信息", dataType = "User")
@PutMapping("update")
public boolean update(User user) {
return userList.remove(user) && userList.add(user);
}
@ApiOperation("批量删除")
@ApiImplicitParam(name = "users", value = "N个用户信息", dataType = "List<User>")
@DeleteMapping("delete")
public boolean delete(@RequestBody List<User> users) {
return userList.removeAll(users);
}
}
package com.hehe.entity;
public class User {
private String userId;
private String username;
private String password;
public User() {
}
public User(String userId, String username, String password) {
this.userId = userId;
this.username = username;
this.password = password;
}
@Override
public boolean equals(Object o) {
if (this == o) {
return true;
}
if (o == null || getClass() != o.getClass()) {
return false;
}
User user = (User) o;
return userId != null ? userId.equals(user.userId) : user.userId == null;
}
@Override
public int hashCode() {
int result = userId != null ? userId.hashCode() : 0;
result = 31 * result + (username != null ? username.hashCode() : 0);
result = 31 * result + (password != null ? password.hashCode() : 0);
return result;
}
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
4. 查阅接口文档
编写文档完成之后,启动当前项目,在浏览器打开:
[ http://localhost:8080/swagger-ui.html ] , 看到效果如下:
来看看save 方法的具体描述,可以看到Swagger 2.7.0 版本对参数列表进行了改版,直接输入参数,更方便进行测试操作:
5. 测试接口
Swagger2的强大之处不仅在于快速生成整洁优雅的RestAPI文档,同时支持接口方法的测试操作(类似于客户端PostMan)。
以查询用户列表为例,无参数输入,直接点击“试一下”按钮:
然后可以看到以JSON格式返回的用户列表信息,很方便有木有:
好了,关于Swagger2在项目中的使用教程就到这里。
