spring中配置log4j,并将log信息存储在数据库中(以mysql为例)

log4j作用及重要性我就不再重复了，可google一下。

第一例：log4j与mysql的配置

需要的jar为：log4j-1.2.16.jar

mysql-connector-java-5.1.22.jar

log4j配置文件：log4j.properties

--------------------------------------------------------------------------------------------------------------------------------------

log4j.rootLogger=INFO,appender1,appender2,appender3

log4j.logger.org.springframework=ERROR

log4j.appender.appender1=org.apache.log4j.ConsoleAppender

log4j.appender.appender1.layout=org.apache.log4j.PatternLayout

log4j.appender.appender1.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss:SSS}[%p]: %m%n

log4j.appender.appender2=org.apache.log4j.FileAppender

log4j.appender.appender2.File=log/IceColdMonitor.log

log4j.appender.appender2.layout=org.apache.log4j.PatternLayout

log4j.appender.appender2.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss:SSS}[%p]: %m%n

#database

log4j.appender.appender3=org.apache.log4j.jdbc.JDBCAppender

log4j.appender.appender3.driver=com.mysql.jdbc.Driver

log4j.appender.appender3.URL=jdbc:mysql://127.0.0.1:3306/test

log4j.appender.appender3.user=test

log4j.appender.appender3.password=test

log4j.appender.appender3.sql=INSERT INTO logging (log_date, log_level, location, message) VALUES ('%d{yyyy-MM-dd hh:mm:ss}','%p','%c','%m')

---------------------------------------------------------------------------------------------------------------------------------------------

测试类：Test

------------------------------------------------------------------------------------

package com.log4j.test;

import org.apache.log4j.Logger;

public class Test {

public static void main(String[] args) {

Logger logger = Logger.getLogger(Test.class);

logger.info("test logger info");

logger.debug("test logger debug");

logger.error("test logger error");

logger.fatal("test logger fatal");

}

}

数据库脚本：

CREATE TABLE `logging` (

`log_date` varchar(50) default NULL,

`log_level` varchar(5) default NULL,

`location` varchar(100) default NULL,

`message` varchar(1000) default NULL

) ENGINE=InnoDB DEFAULT CHARSET=utf8;
