代码侵入式注解
遵循YAML文档格式
非常适合三端(PC、iOS及Android)的API管理,尤其适合前后端完全分离的架构模式。
减少没有必要的文档,符合敏捷开发理念
功能强大
作用接口的文档在线自动生成
功能测试
优点1. 大大减少前后端的沟通
2. 方便查找和测试接口
3. 提高团队的开发效率
4. 方便新人了解项目
配置swagger引入依赖
io.springfox springfox-swagger22.9.2 io.springfox springfox-swagger-ui2.9.2
配置类
@Configuration
@EnableSwagger2
public class SwaggerConfig {
@Bean
public Docket createRestApi() {
return new Docket(documentationType.SWAGGER_2)
//apiInfo指定测试文档基本信息,这部分将在页面展示
.apiInfo(apiInfo())
.select()
//apis() 控制哪些接口暴露给swagger,
// RequestHandlerSelectors.any() 所有都暴露
// RequestHandlerSelectors.basePackage("com.info.*") 指定包位置
.apis(RequestHandlerSelectors.basePackage("com.cbw.admin"))
.paths(PathSelectors.any())
.build();
}
//基本信息,页面展示
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("接口文档")
.description("接口描述")
//联系人实体类
.contact(
new Contact(null, null, null)
)
//版本号
.version("1.0.0")
.build();
}
}
常用注解
swagger通过在controller中,声明注解,API文档进行说明
1、@Api():用在请求的类上,表示对类的说明,也代表了这个类是swagger2的资源
2、@ApiOperation():用于方法,表示一个http请求访问该方法的 *** 作
3、@ApiModel():用于响应实体类上,用于说明实体作用
4、@ApiModelProperty:用在属性上,描述实体类的属性
5、@ApiImplicitParams:用在请求的方法上,包含多@ApiImplicitParam
6、@ApiImplicitParam:用于方法,表示单独的请求参数
7、@ApiParam():用于方法,参数,字段说明 表示对参数的要求和说明
8、@ApiResponses:用于请求的方法上,根据响应码表示不同响应
一个@ApiResponses包含多个@ApiResponse
9、@ApiResponse:用在请求的方法上,表示不同的响应
10、@ApiIgnore():用于类或者方法上,不被显示在页面上
使用实体类
@ApiModel("用户对象模型")
public class User {
private Long id;
private String username;
private String password;
private String email;
}
controller
@RestController
@RequestMapping("/user")
@Api(tags = {"用户管理API"})
public class UserController {
@PostMapping
@ApiOperation(value = "新增用户", notes = "新增后返回当前用户")
@ApiResponses({
@ApiResponse(code = 200, message = "返回成功", response = User.class),
@ApiResponse(code = 400, message = "参数没有填好(id==1)", response = User.class),
@ApiResponse(code = 401, message = "权限不足(id==1)", response = User.class),
})
public ResponseEntity add(User user) {
if (user.getId() == 1) {
return new ResponseEntity<>(user, HttpStatus.BAD_REQUEST); //400
} else if (user.getId() == 2) {
return new ResponseEntity<>(user, HttpStatus.UNAUTHORIZED); //401
} else {
return ResponseEntity.ok(user);
}
}
@PutMapping
@ApiOperation(value = "修改用户", notes = "修改后返回当前用户")
@ApiResponses({
@ApiResponse(code = 200, message = "返回成功", response = User.class),
@ApiResponse(code = 400, message = "参数没有填好(id==1)", response = User.class),
@ApiResponse(code = 401, message = "权限不足(id==1)", response = User.class),
})
public ResponseEntity update(User user) {
if (user.getId() == 1) {
return new ResponseEntity<>(user, HttpStatus.BAD_REQUEST); //400
} else if (user.getId() == 2) {
return new ResponseEntity<>(user, HttpStatus.UNAUTHORIZED); //401
} else {
return ResponseEntity.ok(user);
}
}
@DeleteMapping("/{id}")
@ApiOperation(value = "删除用户", notes = "删除后返回当前id")
@ApiResponses({
@ApiResponse(code = 200, message = "返回成功", response = User.class),
@ApiResponse(code = 400, message = "参数没有填好(id==1)", response = User.class),
@ApiResponse(code = 401, message = "权限不足(id==1)", response = User.class),
})
@ApiImplicitParam(paramType = "path", name = "id", value = "用户主键ID", required = true)
public ResponseEntity delete(@PathVariable Long id) {
if (id == 1) {
return new ResponseEntity<>(id, HttpStatus.BAD_REQUEST); //400
} else if (id == 2) {
return new ResponseEntity<>(id, HttpStatus.UNAUTHORIZED); //401
} else {
return ResponseEntity.ok(id);
}
}
@GetMapping("/{id}")
@ApiIgnore
public ResponseEntity toUpdate(@PathVariable Long id) {
if (id == 1) {
return new ResponseEntity<>(id, HttpStatus.BAD_REQUEST); //400
} else if (id == 2) {
return new ResponseEntity<>(id, HttpStatus.UNAUTHORIZED); //401
} else {
return ResponseEntity.ok(id);
}
}
@PostMapping("/list-page")
@ApiOperation(value = "分页查询", notes = "得到分页查询对象pageInfo")
@ApiImplicitParams({
@ApiImplicitParam(paramType = "query", name = "pageNum", value = "当前页", required = false, defaultValue = "1"),
@ApiImplicitParam(paramType = "query", name = "pageSize", value = "每页行数", required = false, defaultValue = "10")
})
public ResponseEntity findByPage(@RequestParam(defaultValue = "1", required = false) Integer pageNum,
@RequestParam(defaultValue = "10", required = false) Integer pageSize) {
return ResponseEntity.ok("find page result...");
}
}
