Spring Boot（十一）使用AOP，@Aspect统一处理Web请求日志，标记地址：

https://github.com/FrameReserve/TrainingBoot/releases/tag/0.0.11

增加Web层日志切面类：

package com.training.core.aspect;

import org.apache.log4j.Logger;
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.springframework.core.annotation.Order;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;

/**
 * Web层日志切面
 */
@Aspect
@Order(5)
@Component
public class WebLogAspect {

    private Logger logger = Logger.getLogger(getClass());

    ThreadLocal<Long> startTime = new ThreadLocal<>();

    @Pointcut("execution(public * com.training..*.*Controller(..))")
    public void webLog(){}

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        startTime.set(System.currentTimeMillis());

        // 接收到请求，记录请求内容
        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());
        logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());
        logger.info("ARGS : " + Arrays.toString(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);
        logger.info("SPEND TIME : " + (System.currentTimeMillis() - startTime.get()));
    }
