Spring 对请求和返回做处理 RequestBodyAdvice 和 ResponseBodyAdvice

1.ResponseBodyAdvice

package com.zrx.tango2.filter;

import com.alibaba.fastjson.JSONObject;
import com.zrx.tango2.model.BizData;
import com.zrx.tango2.util.Utils;
import org.springframework.core.MethodParameter;
import org.springframework.data.domain.PageImpl;
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.web.bind.annotation.ControllerAdvice;
import org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice;


import java.util.List;
import java.util.Map;

@ControllerAdvice
public class ResponseAdvisor implements ResponseBodyAdvice<Object> {

    @Override
    public boolean supports(MethodParameter returnType, Class<? extends HttpMessageConverter<?>> converterType) {
        return true;
    }

    @Override
    public Object beforeBodyWrite(Object body,
                                  MethodParameter returnType,
                                  MediaType selectedContentType, Class<? extends HttpMessageConverter<?>> selectedConverterType,
                                  ServerHttpRequest request,
                                  ServerHttpResponse response) {


       //body是返回值
       //request是请求
       //在这儿处理


        return body;
    }


}
