使用AOP统一处理Web请求日志

**

一、导入依赖

**

	    
        
			org.springframework.boot
			spring-boot-starter-aop
		

**

二、写个切面类

**

    import java.util.Enumeration;
    
    import javax.servlet.http.HttpServletRequest;
    
    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.stereotype.Component;
    import org.springframework.web.context.request.RequestContextHolder;
    import org.springframework.web.context.request.ServletRequestAttributes;
    
@Aspect
@Component
public class WebLogAspect {
    private Logger logger = Logger.getLogger(getClass());

    @Pointcut("execution(public * com.ykd.web.controller..*.*(..))")  //
    public void webLog() {

    }

    @Before("webLog()")
    public void doBefore(JoinPoint joinPoint) throws Throwable {
        // 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("---------------request----------------");
        logger.info("URL : " + request.getRequestURL().toString());
        logger.info("HTTP_METHOD : " + request.getMethod());
        logger.info("IP : " + request.getRemoteAddr());
        //遍历参数
        Enumeration enu = request.getParameterNames();
        while (enu.hasMoreElements()) {
            String name = (String) enu.nextElement();
            logger.info("name:" + name + "  " + "value:" + request.getParameter(name));
        }
    }

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

**

三、APP配置注解

**

**

四、查看日志
