Spring Boot学习日志（五）结合Swagger管理接口
什么是Swagger
简单来说，Swagger是一个规范了整个开发周期的AIPI文档生成框架（Swagger is the world’s largest framework of API developer tools for the OpenAPI Specification(OAS), enabling development across the entire API lifecycle, from design and documentation, to test and deployment）。使用Swagger可以直接生成API的说明文档。
以 Spring Boot学习日志（四）使用Mybatis的内容为例，经过简单的配置，Swagger自动生成的API文档样式如下：Swagger配置步骤
1， 在 Spring Boot学习日志（四）使用Mybatis的基础上，添加如下Swagger的依赖
<dependency>
<groupId>io.springfoxgroupId>
<artifactId>springfox-swagger2artifactId>
<version>2.7.0version>
dependency>
<dependency>
<groupId>io.springfoxgroupId>
<artifactId>springfox-swagger-uiartifactId>
<version>2.7.0version>
dependency>2，在MybatisDemoApplication的同级目录下，创建Swagger的配置文件
@Configuration
@EnableSwagger2
public class Swagger2Config {
@Bean
public Docket controllerApi() {
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(new ApiInfoBuilder()
.title("Swagger测试文档")
.description("后台接口说明.")
.contact(new Contact("azui007", "http://blog.csdn.net/azui007", null))
.version("版本号:1.0")
.build())
.select()
.apis(RequestHandlerSelectors.basePackage("com.example.mybatis_demo.controller"))
.paths(PathSelectors.any())
.build();
}
}
Configuration表示该类是配置文件。
@EnableSwagger2表示启用Swagger2
select()返回一个ApiSelectorBuilder用来控制Swagger显示的接口范围，这里设置为controller包内所有类。
启动项目代码：
添加说明
进过上述简单的配置之后，Swagger的基本功能就可以用了，但是使用体验欠佳，比如传递过去的参数不知道是什么意思（如下图所示 ） ，不知道哪些参数必填之类的问题就显示了出来，接下来记录如何解决这些问题。
1，添加参数说明
在Entity类中，可以使用@ApiModelProperty添加属性意义的解释说明，使用@ApiParam标识该属性是否为必须输入项。
@ApiParam(required=true)
@ApiModelProperty(value="主键",name="id")
private Integer id;
@ApiModelProperty(value="用户名",name="userName")
private String userName;
@ApiModelProperty(value="用户组",name="groupid")
private Integer groupid;
2，添加接口说明
使用@ApiOperation添加接口意义说明，使用@RequestParam添加接口方法参数说明。
@ApiOperation("得到用户列表")
@RequestMapping(value = "/list", method = RequestMethod.GET)
public Object queryUser(@RequestParam(value = "页数", required = false, defaultValue = "1") Integer pageNum,
@RequestParam(value = "每页显示数量", required = false, defaultValue = "10") Integer pageSize, User user) {
return mapper.queryUser(user);
}
@ApiOperation("添加新用户")
@RequestMapping(value = "/insert", method = RequestMethod.GET)
public Object insertUser(User user) {
return mapper.insertUser(user);
}
@ApiOperation("更新用户信息")
@RequestMapping(value = "/update", method = RequestMethod.GET)
public Object updateUser(User user) {
return mapper.updateUser(user);
}
@ApiOperation("删除用户信息")
@RequestMapping(value = "/delete", method = RequestMethod.GET)
public Object deleteUser(User user) {
return mapper.deleteUser(user);
}运行效果如下：
这里把上面设置的参数的意义，参数是否必须输入以及参数的默认值都显示了出来。
Swagger 汉化
英文的界面已经很清爽了，但是如果是汉语版的就更好了。
那么Swagger如何汉化呢？
1，在resources目录下新建文件夹META-INF\resources，新建swagger-ui.html，将以下内容拷贝进swagger-ui.html内
<html>
<head>
<meta charset="UTF-8">
<title>Swagger UItitle>
<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"/>

html>2，在resources内创建webjars\springfox-swagger-ui\lang文件夹，并在lang文件夹内创建zh-cn.js，内容如下：
'use strict';
/* jshint quotmark: double */
window.SwaggerTranslator.learn({

"Response Class":"响应类",
"Status":"状态",

"Contact the developer":"联系开发者",
"api version":"api版本",
"Response Content Type":"响应Content Type",
"Parameter content type:":"参数类型:",
"fetching resource":"正在获取资源",
"fetching resource list":"正在获取资源列表",
"Explore":"浏览",
"Show Swagger Petstore Example Apis":"显示 Swagger Petstore 示例 Apis",
"Can't read from server. It may not have the appropriate access-control-origin settings.":"无法从服务器读取。可能没有正确设置access-control-origin。",
"Please specify the protocol for":"请指定协议：",
"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"
});
运行结果如下：
