spring aop输出日志中获取request的post参数

  问题：aop 中使用 request.getInputStream()、request.getReader()获取post参数，因为此时存放post参数的流已经关闭，所以报汇报IO异常

解决方案：

一，通过aop切点，读取controller参数

   logger.info("REQUEST：" + JSONObject.toJSONString(joinPoint.getArgs()));

/**

package com.urule.server.config;

@Aspect
@Component
public class LogAspect extends CommonFrmService{
	@Pointcut("execution(public * com.urule.server.controller..*.*(..))")
    public void webLog(){
		
       // this.
    }
@Before("webLog()")
public void doBefore(JoinPoint joinPoint){
    ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
    HttpServletRequest request = attributes.getRequest();
    // 记录下请求内容
    logger.info("URL : " + request.getRequestURL().toString());
    logger.info("HTTP_METHOD : " + request.getMethod());
    logger.info("REQUEST：" + JSONObject.toJSONString(joinPoint.getArgs()));
   }

@AfterReturning(returning = "ret", pointcut = "webLog()")
public void doAfterReturning(Object ret) throws Throwable {
    // 处理完请求，返回内容
    logger.info("RESPONSE : " + ret);
}
}

二，通过过滤器复制流，实现post数据流的读取
