springboot实现不同业务的日志打印到不同的文件中(图文)

第十三双眼睛2019-08-08【Java】人已围观

简介这几天有个项目的日志信息比较多，需要把不同业务的日志打印到不同的文件中去，今天在公司搞了很久都没搞定，晚上回来搞，终于搞定了，记录一下。

项目发布到线上，很难保证不出问题，一旦出了问题，就得看日志来解决，但是如果，所有的日志都写在一个文件中，这个文件会非常大，不利于查找，因此，需要把不同业务的日志打印到不同的日志文件中去，这样，文件小，而且业务分开，便于排错。
1准备一个配置文件logback.xml，其中内容如下：

<?xml version="1.0" encoding="UTF-8" ?>

<configuration>

<appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
</layout>
</appender>

<appender name="request" class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>E://log/request/request.log</File>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
<encoder>
<pattern>%msg%n</pattern>

</encoder> 
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 
<fileNamePattern>E://log/request/request.%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>4</maxHistory>
</rollingPolicy>
</appender>


<appender name="info" class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>E://log/info/info.log</File>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>INFO</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
<encoder>
<pattern>%msg%n</pattern>

</encoder> 
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 
<fileNamePattern>E://log/info/info.%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>4</maxHistory>
</rollingPolicy>
</appender>

<appender name="error" class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>E://log/error/error.log</File>
<filter class="ch.qos.logback.classic.filter.LevelFilter">
<level>ERROR</level>
<onMatch>ACCEPT</onMatch>
<onMismatch>DENY</onMismatch>
</filter>
<encoder>
<pattern>%msg%n</pattern>
<charset>UTF-8</charset>
</encoder> 
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> 
<fileNamePattern>E://log/error/error.%d{yyyy-MM-dd}.log</fileNamePattern>
<maxHistory>4</maxHistory>
</rollingPolicy>
</appender>

<logger name="requestLogger" additivity="false" level="INFO">
<appender-ref ref="request"/>
</logger>

<logger name="infoLogger" additivity="false" level="INFO">
<appender-ref ref="info"/>
</logger>

<logger name="errorLogger" additivity="false" level="ERROR">
<appender-ref ref="error"/>
</logger>

<root level="DEBUG">
<appender-ref ref="consoleLog"/>
</root>

</configuration>

2写一个测试文件

package com.xinchen.springboot1.schedue;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@Component
public class Schedue {


   public Logger infoLogger = LoggerFactory.getLogger("infoLogger");

   public Logger requestLogger = LoggerFactory.getLogger("requestLogger");

   public Logger errorLogger = LoggerFactory.getLogger("errorLogger");





   @Scheduled(cron = "0 0/1 * * * *")
   public void test() {
       requestLogger.debug("requestLogger.debug");
       requestLogger.info("requestLogger.info");
       requestLogger.error("requestLogger.error");


       infoLogger.debug("infoLogger.debug");
       infoLogger.info("infoLogger.info");
       infoLogger.error("infoLogger.error");


       errorLogger.debug("errorLogger.debug");
       errorLogger.info("errorLogger.info");
       errorLogger.error("errorLogger.error");
   }
}

再电脑中的对应位置出现了这三个文件夹
