    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resoureces目录下创建META-INF esoureces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"/>

        <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 esourceswebjarsspringfox-swagger-uilang 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",

        "Can't read swagger JSON from":"无法读取swagger JSON于",
        "Finished Loading Resource Information. Rendering Swagger UI":"已加载资源信息。正在渲染Swagger UI",
        "Unable to read api":"无法读取api",
        "from path":"从路径",
        "server returned":"服务器返回"
    });
    
    

    ===========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。
