问题描述
我没有得到c3p0日志记录,我的 log4j.properties 文件如下:
I am not getting c3p0 logging, my log4j.properties file is as below:
log4j.logger.org.hibernate=INFO, hb
log4j.logger.org.hibernate.SQL=DEBUG
log4j.logger.org.hibernate.type=TRACE
log4j.logger.org.hibernate.hql.ast.AST=info
log4j.logger.org.hibernate.tool.hbm2ddl=warn
log4j.logger.org.hibernate.hql=debug
log4j.logger.org.hibernate.cache=info
log4j.logger.org.hibernate.jdbc=debug

log4j.category.com.mchange.v2.c3p0=info, c3p0
log4j.category.com.mchange.v2.resourcepool=debug, c3p0
下面是一部分我的Spring配置
Below is part of my Spring Config
<bean
id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
<property name="configLocation">
<value>
classpath:hibernate.cfg.xml
</value>
</property>
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.current_session_context_class">org.springframework.orm.hibernate4.SpringSessionContext</prop>
<prop key="hibernate.show_sql">true</prop>

<prop key="hibernate.c3p0.max_statements">50</prop>
<prop key="hibernate.c3p0.idle_test_period">3000</prop>
</props>
</property>
</bean>
<bean name="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
<property name="jdbcUrl" value="jdbc:sqlserver://localhost:1433;DatabaseName=sample" />
<property name="user" value="sa" />
<property name="password" value="sa@123" />
</bean>
但是我正在获取休眠日志,并且还添加了c3p0 jar文件,我缺少了什么?如何知道我的c3p0连接池是否正常工作?
However I am getting hibernate log and I have also c3p0 jar file added, what I am missing? How to know my c3p0 connection pooling is working or not?
推荐答案
在我对c3p0的log4j测试中,我同意Deinum。使用过记录器,而不是类别。即
agreeing with M Deinum, in my log4j tests of c3p0, i've used logger, not category. i.e.
log4j.logger.com.mchange.v2.c3p0=INFO,c3p0
log4j.logger.com.mchange.v2.resourcepool=DEBUG,c3p0
此外,如果需要,您可以强制c3p0登录到log4j由于某种原因,它正在记录到已找到的其他记录库中。在c3p0.properties文件中或作为VM的系统属性,添加
also, you can force c3p0 to log to log4j if for some reason it is logging to some other logging library it has found. in a c3p0.properties file or as a System property to your VM, add
com.mchange.v2.log.MLog=com.mchange.v2.log.log4j.Log4jMLog
祝你好运!
