log4j日誌保存輸出到數據庫

1、log4j配置文件

########################
# JDBC Appender
#######################
log4j.appender.database.Threshold = INFO
#這裏定義了數據源
log4j.appender.database=org.apache.log4j.jdbc.JDBCAppender
# 這玩意就是每次緩存多少條數據而後插入數據庫，爲了演示這裏設置爲1
log4j.appender.database.BufferSize=1
log4j.appender.database.driver=com.mysql.jdbc.Driver
log4j.appender.database.URL=jdbc:mysql://localhost:3306/springmvc?useUnicode=true&characterEncoding=UTF-8
log4j.appender.database.user=root
log4j.appender.database.password=root
log4j.appender.database.sql=insert into log (class,method,create_time,log_level,msg) values ('%C','%M','%d{yyyy-MM-dd hh:mm:ss}','%p','%m')  
log4j.appender.database.layout=org.apache.log4j.PatternLayout
#編碼格式
log4j.appender.database.Encoding=UTF-8

2、使用的是mysql數據庫，須要導入驅動包

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.46</version>
</dependency>

log4j包

<dependency>
    <groupId>log4j</groupId>
    <artifactId>log4j</artifactId>
    <version>1.2.17</version>
</dependency>

3、測試
