使用
@ControllerAdvice&ResponseBodyAdvice攔截Controller方法預設返回引數，統一處理返回值/響應體
1、Controller程式碼
以下是Controller查詢方法原始碼：
/**
* controller
*
* @author yclimb
* @date 2018/6/29.
*/
@RestController
@RequestMapping("/manage/user")
public class TestController {
private Logger logger = LoggerFactory.getLogger(TestController.class);
/**
* 通過會員id獲取會員資訊及詳情
*
* @param id 會員id
* @return app msg
*
* @author yclimb
* @date 2018/6/29
*/
@GetMapping("/edit/{id}")
public AppMessage edit(@PathVariable Integer id) {
if (null == id) {
return AppMessage.error(-3, "會員ID不能為空");
}
// 查詢會員物件
User user = userService.queryById(id);
if (user == null) {
return AppMessage.error(-3, "根據會員ID未查詢到對應會員");
}
return AppMessage.success(user);
}
}
複製程式碼2、攔截處理器
下面已經封裝好了一個攔截處理類以供參考：
package com.yclimb.test;
import org.springframework.core.MethodParameter;
import org.springframework.http.MediaType;
import org.springframework.http.server.ServerHttpRequest;
import org.springframework.http.server.ServerHttpResponse;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice;
/**
* 攔截Controller方法預設返回引數，統一處理返回值/響應體
*
* @author yclimb
* @date 2018/6/29
*/
@ControllerAdvice
public class TestResponseBodyAdvice implements ResponseBodyAdvice {
@Override
public Object beforeBodyWrite(Object o, MethodParameter methodParameter, MediaType mediaType, Class aClass, ServerHttpRequest serverHttpRequest, ServerHttpResponse serverHttpResponse) {
System.out.println("TestResponseBodyAdvice==>beforeBodyWrite:" + o.toString() + ","
+ methodParameter);
return o;
}
@Override
public boolean supports(MethodParameter methodParameter, Class aClass) {
return true;
}
}
