springboot使用AOP统一处理web请求日志

1.引入相关的log4j和aop的依赖包

        
            org.springframework.boot
            spring-boot-starter-log4j
            1.3.8.RELEASE
        
        
        
            org.springframework.boot
            spring-boot-starter-aop
        

2.编写处理web请求的切面

代码如下

package com.example.exceptiondemo.aop;

import java.util.Enumeration;

import javax.servlet.http.HttpServletRequest;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.annotation.AfterReturning;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

@Aspect
@Component
public class WebLogAspect {

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

	@Pointcut("execution(public * com.example.exceptiondemo.controller.*.*(..))")
	public void webLog() {
	}

	/**
	 * 使用AOP前置通知拦截请求参数信息

	 *
	 * 
	 * @param joinPoint
	 * @throws Throwable
	 */
	@Before("webLog()")
	public void doBefore(JoinPoint joinPoint) throws Throwable {
		// 接收到请求，记录请求内容 记录 最多半年数据迁移 云备份 nosql 数据库
		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("IP : " + request.getRemoteAddr());
		Enumeration enu = request.getParameterNames();
		while (enu.hasMoreElements()) {
			String name = (String) enu.nextElement();
			logger.info("name:{},value:{}", name, request.getParameter(name));
		}

	}

	/**
	 * @param ret
	 * @throws Throwable
	 */
	@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);
	}
}
