如何记录JDBC连接活动？

log4jdbc

库可用于记录JDBC连接。将此库添加到POM-

<dependency>    <groupId>org.slf4j</groupId>    <artifactId>slf4j-log4j12</artifactId>    <version>1.6.4</version></dependency><dependency>    <groupId>org.lazyluke</groupId>    <artifactId>log4jdbc-remix</artifactId>    <version>0.2.7</version></dependency>

配置

log4j.properties

。修改日志记录选项以根据自己的需要调整详细信息级别。

log4j.rootLogger=INFO,R, FILElog4j.appender.R=org.apache.log4j.ConsoleAppenderlog4j.appender.R.layout=org.apache.log4j.PatternLayoutlog4j.appender.R.layout.ConversionPattern=%d{ISO8601} %5p %t %c - %m%nlog4j.appender.FILE=org.apache.log4j.DailyRollingFileAppenderlog4j.appender.FILE.layout=org.apache.log4j.PatternLayoutlog4j.appender.FILE.layout.ConversionPattern=%d{ISO8601} %5p %t %c - %m%nlog4j.appender.FILE.File=/home/kshitiz/documents/tomcat.loglog4j.appender.FILE.DatePattern='.'yyyy-MM-dd# Application logging optionslog4j.logger.org.apache=ERRORlog4j.logger.org.springframework.jdbc.core.JdbcTemplate=DEBUGlog4j.logger.MySQL=ERRORlog4j.logger.org.springframework=DEBUGlog4j.logger.jdbc.sqlonly=OFFlog4j.logger.jdbc.sqltiming=ERRORlog4jdbc.sqltiming.error.threshold=10log4j.logger.jdbc.audit=OFFlog4j.logger.jdbc.resultset=ERRORlog4j.logger.jdbc.connection=ALLlog4j.logger.jdbc.resultsettable=OFF# Setup vm levelslog4j.logger.vm.none=FATALlog4j.logger.vm.error=ERRORlog4j.logger.vm.warn=WARNlog4j.logger.vm.info=INFOlog4j.logger.vm.debug=DEBUG

配置数据源。

<bean id="dataSource"destroy-method="close">        <property name="driverClass" value="net.sf.log4jdbc.DriverSpy" />        <property name="jdbcUrl" value="${db.jdbc.url}" />        <property name="user" value="${db.user}" />        <property name="password" value="${db.password}" />     <!--         these are C3P0 properties -->        <property name="acquireIncrement" value="3" />        <property name="minPoolSize" value="10" />        <property name="maxPoolSize" value="30" />        <property name="maxIdleTime" value="600" /></bean>

关于上述数据源配置的注意事项：

1. 您通常的驱动程序类名称应替换为

   net.sf.log4jdbc.DriverSpy

2. 现在，您的JDBC URL必须以开头

   jdbc:log4jdbc

   。因此，如果您使用Oracle，则JDBC URL现在将以开头

   jdbc:log4jdbc:oracle

   。

现在，日志消息将出现在屏幕上-

一些Mysql命令显示连接详细信息-

> show variables like '%timeout%';> show status like '%onn%';> show full processlist;
