Springboot 获取响应信息，修改响应信息

通过拦截器只能获取到controller下的
restcontroller不能通过拦截器实现

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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.http.server.ServletServerHttpResponse;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

/**

@ControllerAdvice
public class ResponseBodyTest implements ResponseBodyAdvice<R> {

    private static final Logger logger = LoggerFactory.getLogger(ResponseBodyTest.class);


    @Override
    public boolean supports(MethodParameter methodParameter, Class<? extends HttpMessageConverter<?>> aClass) {

        return true;

    }


    //获取响应信息 修改响应  restResult.put覆盖响应消息
    @Override
    public R beforeBodyWrite(R restResult, MethodParameter methodParameter,
                             MediaType mediaType,

                             ServerHttpRequest serverHttpRequest,
                             ServerHttpResponse serverHttpResponse) {
        //System.out.println("测试返回");
        // 转换对象
        HttpServletRequest request = ((ServletServerHttpRequest) serverHttpRequest).getServletRequest();
        HttpServletResponse response = ((ServletServerHttpResponse) serverHttpResponse).getServletResponse();

        logger.info("____________________________________________________________");
        logger.info(methodParameter.getDeclaringClass().getName());
        if ((Boolean) restResult.get("success")){
            logger.info(methodParameter.getMethod().getName()+"方法返回值:"+restResult.get("msg"));
        }else {
            logger.error(methodParameter.getMethod().getName()+"方法返回值:"+restResult.get("msg"));
        }
        logger.info("------------------------------------------------------------");
        //修改响应信息  直接覆盖掉就可以了 响应类是map
        restResult.put("msg","返回信息")
        return restResult;
    }
}

响应类
