使用 ResponseBodyAdvice 拦截Controller方法默认返回参数，统一处理返回值/响应体

@ControllerAdvice

ResponseBodyAdvice

1、Controller代码

以下是Controller查询方法源码：

/**
* controller
*
* @author yclimb
* @date 2018/6/29.
*/
@RestController
@RequestMapping("/manage/user")
public class TestController {

private Logger logger = LoggerFactory.getLogger(TestController.class);

/**
* 通过会员id获取会员信息及详情
*
* @param id 会员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, "会员ID不能为空");
}

// 查询会员对象
User user = userService.queryById(id);
if (user == null) {
return AppMessage.error(-3, "根据会员ID未查询到对应会员");
}

return AppMessage.success(user);
}

}

2、拦截处理器

下面已经封装好了一个拦截处理类以供参考：

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;

/**
* 拦截Controller方法默认返回参数，统一处理返回值/响应体
*
* @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;
}
}
