Ros*_*ver 23 java logging hibernate log4j jboss6.x
我正在尝试创建一个hibernate语句的日志.我使用JPA执行我的sql语句,其中Hibernate 2.0是持久性提供程序(我的应用程序服务器是JBoss AS 6.0).我使用EJB 3.0提供的EntityManager接口调用我的CRUD方法.我读了许多关于启用hinernate日志记录的帖子,但实际上我看不到任何日志:-(我创建了一个log4j.properties文件,我将它放在我的Netbeans项目的根文件夹中.我还将log4j库放在了类的路径中我的log4j.properties是以下内容:
### direct log messages to stdout ###
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{ABSOLUTE} %5p %c{1}:%L – %m%n
log4j.rootLogger=debug, stdout
log4j.logger.org.hibernate=info
### log just the SQL
log4j.logger.org.hibernate.SQL=debug
### log JDBC bind parameters ###
log4j.logger.org.hibernate.type=info
### log schema export/update ###
log4j.logger.org.hibernate.tool.hbm2ddl=info
### log HQL parse trees
#log4j.logger.org.hibernate.hql=debug
### log cache activity ###
log4j.logger.org.hibernate.cache=info
### log transaction activity
#log4j.logger.org.hibernate.transaction=debug
### log JDBC resource acquisition
#log4j.logger.org.hibernate.jdbc=debug
为什么我看不到日志信息？我想看看sql where子句或insert语句中的值(实际上我只看到一些'？')提前感谢.
为清楚起见,我在项目的文件夹结构下面:

必须在hibernate配置中启用Hibernate日志记录.
添加行
hibernate.show_sql=true
hibernate.format_sql=true
要么
server\default\deployers\ejb3.deployer\META-INF\jpa-deployers-jboss-beans.xml
或应用程序的persistence.xml在<persistence-unit><properties>标签.
无论如何,hibernate日志记录将不包括(以有用的形式)实际预准备语句参数的信息.
有一种将log4jdbc用于任何类型的sql日志记录的替代方法.
上面的答案假设您在JBoss上运行使用hibernate的代码,而不是在IDE中运行.在这种情况下,您还应该在server\default\deploy\_jboss-logging.xml中的JBoss上配置日志记录,而不是在本地IDE类路径中.
请注意,JBoss 6默认不使用log4j.因此将log4j.properties添加到ear将无济于事.只是尝试添加到jboss-logging.xml:
<logger category="org.hibernate">
<level name="DEBUG"/>
</logger>
然后更改根记录器的阈值.请参阅SLF4J logger.debug()未登录JBoss 6.
如果你设法直接从IDE调试hibernate查询(没有部署),那么你应该在classpath上有log4j.properties,log4j,slf4j-api和slf4j-log4j12 jar.请参阅http://www.mkyong.com/hibernate/how-to-configure-log4j-in-hibernate-project/.
我回答自己.正如Vadzim所建议的那样,我必须考虑jboss-logging.xml文件并插入以下行:
<logger category="org.hibernate">
<level name="TRACE"/>
</logger>
而不是DEBUG级别我写了TRACE.现在不要只查看控制台,而是打开server.log文件(调试消息不会发送到控制台,但您可以配置此模式!).
