由于 Spring Boot 能够快速开发、便捷部署等特性，通常在使⽤ Spring Boot 构建 Restful 接⼝应⽤ 时考虑到多终端的原因，这些终端会共⽤很多底层业务逻辑，因此我们会抽象出这样⼀层来同时服务于 多个移动端或者Web 前端。对于不同的终端公⽤⼀套接⼝ API 时，对于联调测试的时候就需要知道后端 提供的接⼝ API列表⽂档，对于服务端开发⼈员来说就需要编写接⼝⽂档，描述接⼝的调⽤地址、参数 结果等，这⾥借助第三⽅构建⼯具 Swagger2 来实现 API ⽂档⽣成功能。
1 环境整合配置
pom.xml 依赖添加：
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.9.2</version>
</dependency>
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.9.2</version>
</dependency>配置类添加：
@Configuration
@EnableSwagger2
public class Swagger2 {@Beanpublic Docket createRestApi() {return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).select().apis(RequestHandlerSelectors.basePackage("com.xxxx.springboot.controller")).paths(PathSelectors.any()).build();}private ApiInfo apiInfo() {return new ApiInfoBuilder().title("⽤户管理接⼝API⽂档").version("1.0").build();}
}
2 Swagger2 常⽤注解说明
2.1 @Api
@Api：⽤在请求的类上，说明该类的作⽤tags="说明该类的作⽤"@Api(tags="APP⽤户注册Controller")2.2 @ApiOperation
@ApiOperation："⽤在请求的⽅法上，说明⽅法的作⽤"value="说明⽅法的作⽤"notes="⽅法的备注说明"@ApiOperation(value="⽤户注册",notes="⼿机号、密码都是必填项，年龄是选填项，但必须是数
字")2.3 @ApiImplicitParams
@ApiImplicitParams：⽤在请求的⽅法上，包含⼀组参数说明@ApiImplicitParam：⽤在 @ApiImplicitParams 注解中，指定⼀个请求参数的配置信息 name：参数名value：参数的汉字说明、解释required：参数是否必须传paramType：参数放在哪个地⽅· header --> 请求参数的获取：@RequestHeader· query --> 请求参数的获取：@RequestParam· path（⽤于restful接⼝）--> 请求参数的获取：@PathVariable· body（不常⽤）· form（不常⽤） dataType：参数类型，默认String，其它值dataType="Integer" defaultValue：参数的默认值@ApiImplicitParams({@ApiImplicitParam(name="mobile",value="⼿机
号",required=true,paramType="form"),@ApiImplicitParam(name="password",value="密
码",required=true,paramType="form"),@ApiImplicitParam(name="age",value="年
龄",required=true,paramType="form",dataType="Integer")
})
2.4 @ApiResponses
@ApiResponses：⽤于请求的⽅法上，表示⼀组响应@ApiResponse：⽤在@ApiResponses中，⼀般⽤于表达⼀个错误的响应信息code：数字，例如400message：信息，例如"请求参数没填好"response：抛出异常的类@ApiOperation(value = "select请求", notes = "多个参数，多种的查询参数类型")
@ApiResponses({@ApiResponse(code=400, message="请求参数没填好"),@ApiResponse(code=404, message="请求路径没有或⻚⾯跳转路径不对")
})2.5 @ApiModel
@ApiModel：⽤于响应类上，表示⼀个返回响应数据的信息（这种⼀般⽤在post创建的时候，使⽤@RequestBody这样的场景，请求参数⽆法使⽤@ApiImplicitParam注解进⾏描述的时候）@ApiModelProperty：⽤在属性上，描述响应类的属性@ApiModel(description= "返回响应数据")
public class RestMessage implements Serializable{@ApiModelProperty(value = "是否成功")private boolean success=true;@ApiModelProperty(value = "返回对象")private Object data;@ApiModelProperty(value = "错误编号")private Integer errCode;@ApiModelProperty(value = "错误信息")private String message;/* getter/setter */
}3 用户模块注解配置
3.1 Controller 使用注解
@GetMapping("user/{userName}")
@ApiOperation(value = "根据⽤户名查询⽤户记录")
@ApiImplicitParam(name = "userName",value = "查询参数",required = true,paramType
= "path")
public User queryUserByUserName(@PathVariable String userName){return userService.queryUserByUserName(userName);
}
@ApiOperation(value = "根据⽤户id查询⽤户记录")
@ApiImplicitParam(name = "userId",value = "查询参数",required = true,paramType =
"path")
@GetMapping("user/id/{userId}")
public User queryUserByUserId(@PathVariable Integer userId,
HttpServletRequest request){return userService.queryUserByUserId(userId);
}
@GetMapping("user/list")
@ApiOperation(value = "多条件查询⽤户列表记录")
public PageInfo<User> list(UserQuery userQuery){return userService.queryUserByParams(userQuery);
}
@PutMapping("user")
@ApiOperation(value = "⽤户添加")
@ApiImplicitParam(name = "user",value = "⽤户实体类",dataType = "User")
public ResultInfo saveUser(@RequestBody User user){ResultInfo resultInfo=new ResultInfo();try {userService.saveUser(user);} catch (ParamsException e) {e.printStackTrace();resultInfo.setCode(e.getCode());resultInfo.setMsg(e.getMsg());}catch (Exception e) {e.printStackTrace();resultInfo.setCode(300);resultInfo.setMsg("记录添加失败!");}return resultInfo;
}
@PostMapping("user")
@ApiOperation(value = "⽤户更新")
@ApiImplicitParam(name = "user",value = "⽤户实体类",dataType = "User")
public ResultInfo updateUser(@RequestBody User user){ResultInfo resultInfo=new ResultInfo();try {userService.updateUser(user);} catch (ParamsException e) {e.printStackTrace();resultInfo.setCode(e.getCode());resultInfo.setMsg(e.getMsg());}catch (Exception e) {e.printStackTrace();resultInfo.setCode(300);resultInfo.setMsg("记录更新失败!");}return resultInfo;
}
@PutMapping("user/{userId}")
@ApiOperation(value = "根据⽤户id删除⽤户记录")
@ApiImplicitParam(name = "userId",value = "查询参数",required = true,paramType =
"path")
public ResultInfo deleteUser(@PathVariable Integer userId){ResultInfo resultInfo=new ResultInfo();try {userService.deleteUser(userId);} catch (ParamsException e) {e.printStackTrace();resultInfo.setCode(e.getCode());resultInfo.setMsg(e.getMsg());}catch (Exception e) {e.printStackTrace();resultInfo.setCode(300);resultInfo.setMsg("记录删除失败!");}return resultInfo;
}3.2 JavaBean 使用注解
User.java
@ApiModel(description = "响应结果-⽤户信息")
public class User {@ApiModelProperty(value = "⽤户id",example = "0")private Integer id;@ApiModelProperty(value = "⽤户名")private String userName;@ApiModelProperty(value = "⽤户密码")private String userPwd;/*省略get|set*/
}
UserQuery.java
@ApiModel(description = "⽤户模块条件查询类")
public class UserQuery {@ApiModelProperty(value = "分⻚⻚码",example = "1")private Integer pageNum = 1;@ApiModelProperty(value = "每⻚⼤⼩",example = "10")private Integer pageSize = 10;@ApiModelProperty(value = "⽤户名")private String userName;/*省略get|set*/}ResultInfo.java
@ApiModel(description = "响应结果 - Model信息")
public class ResultInfo {@ApiModelProperty(value = "响应状态码",example = "200")private Integer code=200;@ApiModelProperty(value = "响应消息结果")private String msg = "success";@ApiModelProperty(value = "响应具体结果信息")private Object result;/*省略get|set*/
}
