因為專案的需要，要對反會的值進行處理，我使用的 spring  

@ControllerAdvice 註解進行處理

以前的介面有一部分是返回string，所以要進行相容

package com.threeti.danfoss.base.interceptor;

import javax.servlet.http.HttpServletRequest;

import org.springframework.core.MethodParameter;
import org.springframework.http.MediaType;
import org.springframework.http.converter.HttpMessageConverter;
import org.springframework.http.server.ServerHttpRequest;
import org.springframework.http.server.ServerHttpResponse;
import org.springframework.http.server.ServletServerHttpRequest;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice;
import org.springframework.web.servlet.support.RequestContext;

import com.threeti.danfoss.base.entity.XaResult;

@ControllerAdvice(basePackages ={"com.threeti.danfoss.base.controller","com.threeti.danfoss.business.controller"})
public class MyResponseBodyAdvice implements ResponseBodyAdvice<Object> {
	
	
	@Override
	public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
		//獲取當前處理請求的controller的方法
		//String methodName=returnType.getMethod().getName(); 
		/*// 不攔截/不需要處理返回值 的方法
		String method= "loginCheck"; //如登入
		//不攔截
		if(method.equals(methodName))
		{
		return false;
		}*/ 
		return true;
	}
	

	/*@Override
	public T beforeBodyWrite(T body, MethodParameter returnType, MediaType selectedContentType,
			Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request,
			ServerHttpResponse response) {
		// TODO Auto-generated method stub
		return null;
	}*/


	@Override
	public Object beforeBodyWrite(Object body, MethodParameter returnType, MediaType selectedContentType,
			Class<? extends HttpMessageConverter<?>> selectedConverterType, ServerHttpRequest request,
			ServerHttpResponse response) {
		if(body instanceof XaResult){
			XaResult xr = (XaResult) body;
			String message = xr.getMessage();//獲取message
			
			ServletServerHttpRequest req = (ServletServerHttpRequest) request;
			HttpServletRequest httpReq = req.getServletRequest();
			
			RequestContext myreq = new RequestContext(httpReq);
			
			try{
				if(xr.getMsgParams() == null){
					message = myreq.getMessage(message);
				}else{
					message = myreq.getMessage(message,xr.getMsgParams());
				}
			}catch(Exception e){
				message=myreq.getMessage("defined");
			}
			
			xr.setMessage(message);
			return xr;
		}else{
			return String.valueOf(body);
		}

	}

}
 

因為做的 介面大部分是用定義的物件 XaResult 返回

@ResponseBody
	@RequestMapping(value="findProductCodeByStation",method=RequestMethod.POST)
	public XaResult<List<ProductCode>> findProductCodeByStation(
			@RequestParam(value = "station") String station,
			HttpServletRequest request
		) throws BusinessException{
		//Long userId = WebUitl.getCmsLoginedUserId(request);
		return productCodeService.findProductCodeByStation(station);
	}
