本文介绍如何在项目中整合SLF4J、Logback等日志框架，并通过Spring AOP实现Web请求的日志记录，包括配置POM文件、logback.xml，以及编写切面类。

添加pom.xml文件

        <dependency>
			<groupId>org.slf4j</groupId>
			<artifactId>slf4j-api</artifactId>
			<version>1.7.21</version>
		</dependency>
		<dependency>
			<groupId>ch.qos.logback</groupId>
			<artifactId>logback-classic</artifactId>
			<version>1.1.7</version>
		</dependency>
		<dependency>
			<groupId>ch.qos.logback</groupId>
			<artifactId>logback-core</artifactId>
			<version>1.1.7</version>
		</dependency>
		<dependency>
			<groupId>org.logback-extensions</groupId>
			<artifactId>logback-ext-spring</artifactId>
			<version>0.1.4</version>
		</dependency>

添加logback.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration>
<configuration scan="true" scanPeriod="60 seconds" debug="false">
	<property resource="/config/logback.properties" />
	<!--控制台输出 -->
	<appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
	<!--按天生成日志 -->
	<appender name="logfile" class="ch.qos.logback.core.rolling.RollingFileAppender">
	 	<Prudent>true</Prudent>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <FileNamePattern>
                ${log.file}/logs/%d{yyyy-MM-dd}/%d{yyyy-MM-dd}.log
            </FileNamePattern>
        </rollingPolicy>
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %d{yyyy-MM-dd HH:mm:ss} -%msg%n
            </Pattern>
        </layout>
    </appender>

    <root>
        <level value="${log.level}" />
        <appender-ref ref="console"/>
        <appender-ref ref="logfile" />
    </root>
</configuration>

logback.properties配置文件，确定日志级别，和输出文件位置

log.level=info
log.file=E:/dev3/apache-tomcat-7.0.47

编写切面类WebLogAspect

package com.dw.common.aspect;

import org.aspectj.lang.JoinPoint;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.aspectj.lang.reflect.MethodSignature;
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;
import sun.net.util.IPAddressUtil;

import javax.servlet.http.HttpServletRequest;
import java.lang.reflect.Method;
import java.util.Arrays;

@Aspect
@Component
public class WebLogAspect {

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

    @Pointcut("execution( * com.dw.controller..*.*(..))")//两个..代表所有子目录，最后括号里的两个..代表所有参数
    public void logPointCut() {
    }


    @Before("logPointCut()")
    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("请求地址 : " + request.getRequestURL().toString());
        logger.info("HTTP METHOD : " + request.getMethod());
        logger.info("CLASS_METHOD : " + joinPoint.getSignature().getDeclaringTypeName() + "."
                + joinPoint.getSignature().getName());
        logger.info("参数 : " + Arrays.toString(joinPoint.getArgs()));

    }

    @AfterReturning(returning = "ret", pointcut = "logPointCut()")// returning的值和doAfterReturning的参数名一致
    public void doAfterReturning(Object ret) throws Throwable {
        // 处理完请求，返回内容(返回值太复杂时，打印的是物理存储空间的地址)
        logger.debug("返回值 : " + ret);
    }

    @Around("logPointCut()")
    public Object doAround(ProceedingJoinPoint pjp) throws Throwable {
        long startTime = System.currentTimeMillis();
        Object ob = pjp.proceed();// ob 为方法的返回值
        logger.info("耗时 : " + (System.currentTimeMillis() - startTime));
        return ob;
    }
}

springMvc中开启aop，对切面类代理

    <!-- 开启aop，对类代理 -->
	<aop:aspectj-autoproxy proxy-target-class="true" />
	<bean id="webLogAspect" class="com.dw.common.aspect.WebLogAspect"/>

效果
