## 1 项目集成log4j ##

### 1.1 加入pom依赖 ###

### 1.2 加入log4j.properties ###

log4j.rootLogger=debug,stdout,debug,info,warn,error
    ### 输出信息到控制抬
    log4j.appender.stdout=org.apache.log4j.ConsoleAppender
    log4j.appender.stdout.Target=System.out
    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
    log4j.appender.stdout.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n
    ### 输出DEBUG 级别以上的日志到 log/debug.log
    log4j.appender.debug=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.debug.File=log/integrate-log4j-debug.log
    log4j.appender.debug.Append=true
    log4j.appender.debug.Threshold=DEBUG
    log4j.appender.debug.layout=org.apache.log4j.PatternLayout
    log4j.appender.debug.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n
    ### 输出DEBUG 级别以上的日志到 log/debug.log
    log4j.appender.info=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.info.File=log/integrate-log4j-info.log
    log4j.appender.info.Append=true
    log4j.appender.info.Threshold=INFO
    log4j.appender.info.layout=org.apache.log4j.PatternLayout
    log4j.appender.info.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n
    ### 输出DEBUG 级别以上的日志到 log/debug.log
    log4j.appender.warn=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.warn.File=log/integrate-log4j-warn.log
    log4j.appender.warn.Append=true
    log4j.appender.warn.Threshold=WARN
    log4j.appender.warn.layout=org.apache.log4j.PatternLayout
    log4j.appender.warn.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n
    ### 输出ERROR 级别以上的日志到 log/error.log
    log4j.appender.error=org.apache.log4j.DailyRollingFileAppender
    log4j.appender.error.File=log/integrate-log4j-error.log
    log4j.appender.error.Append=true
    log4j.appender.error.Threshold=ERROR
    log4j.appender.error.layout=org.apache.log4j.PatternLayout
    log4j.appender.error.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

### 1.3 在代码中使用 ###

package com.zjw; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class Log4jTest { private static Logger logger = LoggerFactory.getLogger(Log4jTest.class); public static void main(String[] args) { logger.info("Log4j test."); } }
