关于在项目中,Log4jConfigListener过时的解决方法
进入 Log4jConfigListener 类,可以看到类上面的@deprecated的注释:
 
大致意思的就是提示我们使用log4j 2来替代 log4j。
根据官方的提示,在项目中去掉log4j相关依赖,然后引入log4j2的相关依赖:
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.10.0</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.10.0</version>
</dependency>

<dependency>
  <groupId>org.apache.logging.log4j</groupId>
  <artifactId>log4j-web</artifactId>
  <version>2.9.1</version>
</dependency>
接下来,在web.xml中配置如下:
<!-- log4j2 Start -->
<listener>
    <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
</listener>
<filter>
    <filter-name>log4jServletFilter</filter-name>
    <filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>log4jServletFilter</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
    <dispatcher>INCLUDE</dispatcher>
    <dispatcher>ERROR</dispatcher>
</filter-mapping>
<!-- log4j2 End -->
在resources下面添加log4j2.xml配置文件:
<?xml version="1.0" encoding="UTF-8"?>
<!--日志级别以及优先级排序: OFF > FATAL > ERROR > WARN > INFO > DEBUG > TRACE > ALL -->

<!--Configuration后面的status,这个用于设置log4j2自身内部的信息输出,可以不设置,当设置成trace时,你会看到log4j2内部各种详细输出-->

<!--monitorInterval:Log4j能够自动检测修改配置 文件和重新配置本身,设置间隔秒数-->
<Configuration status="INFO" monitorInterval="1800">
    <properties>
        <property name="LOG_HOME">${web:rootDir}/logs</property>
        <property name="FILE_NAME">finance-pay</property>
    </properties>

    <!--先定义所有的appender-->
    <Appenders>

        <!--这个输出控制台的配置-->
        <Console name="Console" target="SYSTEM_OUT">
            <!--输出日志的格式-->
            <!--<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />-->
            <PatternLayout pattern="%d %-5p %c - %m%n" />
        </Console>

        <!--文件会打印出所有信息,这个log每次运行程序会自动清空,由append属性决定,这个也挺有用的,适合临时测试用-->
        <File name="log" fileName="log/test.log" append="false">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} %-5level %class{36} %L %M - %msg%xEx%n"/>
        </File>


        <!-- 这个会打印出所有的info及以下级别的信息,每次大小超过size,则这size大小的日志会自动存入按年份-月份建立的文件夹下面并进行压缩,作为存档-->
        <RollingFile name="running-log" fileName="${LOG_HOME}/${FILE_NAME}.log"
                     filePattern="${LOG_HOME}/$${date:yyyy-MM}/${FILE_NAME}-%d{yyyy-MM-dd}-%i.log.gz"
                     immediateFlush="true">
            <!--控制台只输出level及以上级别的信息(onMatch),其他的直接拒绝(onMismatch)-->
            <ThresholdFilter level="info" onMatch="ACCEPT" onMismatch="DENY"/>
            <PatternLayout pattern="%date{yyyy-MM-dd HH:mm:ss.SSS} %level [%thread][%file:%line] - %msg%n" />
            <Policies>
                <TimeBasedTriggeringPolicy />
                <SizeBasedTriggeringPolicy size="10 MB" />
            </Policies>
            <DefaultRolloverStrategy max="20" />
        </RollingFile>


        <RollingFile name="RollingFileWarn" fileName="${LOG_HOME}/warn.log"
                     filePattern="${sys:user.home}/logs/$${date:yyyy-MM}/warn-%d{yyyy-MM-dd}-%i.log">
            <ThresholdFilter level="warn" onMatch="ACCEPT" onMismatch="DENY"/>
            <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
            <Policies>
                <TimeBasedTriggeringPolicy/>
                <SizeBasedTriggeringPolicy size="100 MB"/>
            </Policies>
            <!-- DefaultRolloverStrategy属性如不设置,则默认为最多同一文件夹下7个文件,这里设置了20 -->
            <DefaultRolloverStrategy max="20"/>
        </RollingFile>


        <RollingFile name="RollingFileError" fileName="${LOG_HOME}/error.log"
                     filePattern="${sys:user.home}/logs/$${date:yyyy-MM}/error-%d{yyyy-MM-dd}-%i.log">
            <ThresholdFilter level="error" onMatch="ACCEPT" onMismatch="DENY"/>
            <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>
            <Policies>
                <TimeBasedTriggeringPolicy />
                <SizeBasedTriggeringPolicy size="100 MB"/>
            </Policies>
        </RollingFile>

    </Appenders>

    <!--然后定义logger,只有定义了logger并引入的appender,appender才会生效-->
    <Loggers>

        <!--过滤掉spring和mybatis的一些无用的DEBUG信息-->
        <logger name="org.springframework" level="INFO"></logger>
        <logger name="org.mybatis" level="INFO"></logger>

        <Root level="all">
            <!-- 这里是输入到文件,很重要-->
            <AppenderRef ref="running-log" />
            <!-- 这里是输入到控制台-->
            <AppenderRef ref="Console" />
            <appender-ref ref="RollingFileInfo"/>
            <appender-ref ref="RollingFileWarn"/>
            <appender-ref ref="RollingFileError"/>
        </Root>

    </Loggers>
</Configuration>
配置完成之后,我们可以在方法中写一段测试代码来测试一下日志相关配置是否配置正确。‘
package com.baikeyang.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.baikeyang.controller.music.MusicFMController;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/teana")
public class MessageController {

    private final static Logger log = LogManager.getLogger(MusicFMController.class);

    @RequestMapping("")
    public String index(HttpServletRequest request, HttpServletResponse response){
        return "start";
    }
    
    @RequestMapping("/start/{name}/{age}")
    public String start(@PathVariable("name") String name, @PathVariable("age") int age) {
        log.error("姓名:" + name + ", 年龄:" + age);
        log.trace("trace message");
        log.debug("debug message");
        log.info("info message");
        log.warn("warn message");
        log.error("error message");
        log.fatal("fatal message");
        System.out.println("Hello World!");
        return "login";
    }
    
    public static void main(String[] args) {
        log.trace("trace message");
        log.debug("debug message");
        log.info("info message");
        log.warn("warn message");
        log.error("error message");
        log.fatal("fatal message");
        System.out.println("Hello World!");
    }
    
}
