如何在Tomcat中将级别日志记录设置为DEBUG?

我想在tomcat中将级别日志记录设置为DEBUG,但是在控制台中,仍然只有INFO和WARN输出。有人可以告诉我怎么了吗?

回答:

首先,要使用的级别名称FINE不是DEBUG。让我们假设一分钟DEBUG实际上是有效的,因为这使得下面的解释更有意义…

在本Handler specific

properties节中,您将这些处理程序的日志记录级别设置为DEBUG。这意味着处理程序将处理任何DEBUG级别或更高级别的日志消息。这并不一定意味着DEBUG实际上已将任何消息传递给处理程序。

在本Facility specific

properties节中,您将一些明确命名的记录器的记录级别设置为DEBUG。对于那些记录器,任何级别DEBUG或更高级别的记录都

传递给处理程序。

默认日志记录级别是INFO,除了本Facility specific properties节中提到的记录器之外,所有记录器都将具有该级别。

如果要查看所有FINE消息,请添加以下内容:

.level = FINE

但是,这将生成大量的日志消息。设置代码的日志记录级别可能更有用:

your.package.level = FINE

有关更多信息,请参见Tomcat 6 /

Tomcat

7日志记录文档。此处显示的示例logging.properties文件使用FINE代替DEBUG

...

1catalina.org.apache.juli.FileHandler.level = FINE

...

并提供了设置其他日志记录级别的示例:

# For example, set the com.xyz.foo logger to only log SEVERE

# messages:

#org.apache.catalina.startup.ContextConfig.level = FINE

#org.apache.catalina.startup.HostConfig.level = FINE

#org.apache.catalina.session.ManagerBase.level = FINE
