SpringBoot日志管理【log4j】

SpringBoot日志管理

目的：使用log4j记录日志，使用AOP统一处理Web请求日志

步骤1：新建log4j配置文件,文件名称log4j.properties

log4j.rootLogger=INFO,Console,File
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c - %L]%m%n
log4j.appender.File = org.apache.log4j.RollingFileAppender
log4j.appender.File.File = e:/logs/info/info.log
log4j.appender.File.MaxFileSize = 10MB
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c - %L]%m%n

步骤2：添加maven依赖

<!-- spring boot start -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<!-- 排除自带的logback依赖 -->
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>

<!-- springboot-log4j -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-log4j</artifactId>
<version>1.3.8.RELEASE</version>
</dependency>

步骤3：aop模块

1：

package com.web.aspect;


import org.apache.log4j.Logger;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestAttributes;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

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

@Component
@Aspect
public class LogAspect {

    //定义日志对象
    private static final Logger logger = Logger.getLogger(LogAspect.class);

    //切入点
    @Pointcut("execution(public * com.web.controller.*.*(..))")
    public void myPointcut(){}

    //前置通知
    @Before("myPointcut()")
    public void before(){
        logger.info("method start..");
        //通过请求对象上下文获取请求对象属性集
        ServletRequestAttributes attr = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        //获取请求对象
        HttpServletRequest request = attr.getRequest();
        logger.info("session:"+request.getSession().getAttribute("username"));
        logger.info("url:"+request.getRequestURL());
        logger.info("ip:"+request.getRemoteAddr());
        logger.info("port:"+request.getRemotePort());
        Enumeration<String> en = request.getParameterNames();
        while(en.hasMoreElements()){
            String name = en.nextElement();
            String value = request.getParameter(name);
            logger.info("name:"+name+"  value:"+value);
        }
    }

    @After("myPointcut()")
    public void after(){
        logger.info("method end...");
    }

    @AfterThrowing(value = "myPointcut()",throwing = "e")
    public void afterThrowing(Exception e){
        logger.error("test fail-",e);
    }

    @AfterReturning(value = "myPointcut()",returning = "obj")
    public void afterReturning(Object obj){
        logger.info("return "+obj);
    }

}

2：

package com.web.aspect;

import com.web.entity.User;
import org.apache.log4j.Logger;
import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;
import org.springframework.stereotype.Component;

import java.util.Arrays;

@Component
@Aspect
public class ServiceLogAspect {

    //定义日志对象
    private static final Logger logger = Logger.getLogger(ServiceLogAspect.class);

    @Pointcut("execution(public * com.web.service.*.*(..))")
    public void servicePointcut(){}

    @Around("servicePointcut()")
    public Object around(ProceedingJoinPoint pjp){
        Object obj=null;
        try {
            logger.info("method start:"+pjp.getSignature());
            logger.info("args:"+ Arrays.toString(pjp.getArgs()));
            obj = pjp.proceed();//执行原始方法
            logger.info("method end..");
        } catch (Throwable throwable) {
            throwable.printStackTrace();
        }
        return obj;
    }

}

只需要配置aop其他包中正常使用。
