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)@Componentpublic 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()));    }}
