- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我想在 tomcat 中将级别日志记录设置为 DEBUG,但在控制台中仍然只有 INFO 和 WARN 输出。谁能告诉我哪里出了问题?

最佳答案
首先,要使用的级别名称是FINE
,而不是DEBUG
。让我们暂时假设 DEBUG
实际上是有效的,因为它使下面的解释更有意义......
在 Handler specific properties
部分,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具有 DEBUG
级别或更高级别的日志消息。这并不一定意味着任何 DEBUG
消息实际上都传递给了处理程序。
在 Facility specific properties
部分,您将一些明确命名的记录器的日志记录级别设置为 DEBUG
。对于这些记录器,DEBUG
或更高级别的任何内容都将 传递给处理程序。
默认的日志级别是INFO
,除了Facility specific properties
部分提到的记录器之外,所有记录器都将具有该级别。
如果您想查看所有FINE
消息,请添加:
.level = FINE
但是,这会产生大量的日志消息。为您的代码设置日志记录级别可能更有用:
your.package.level = FINE
参见 Tomcat 6/Tomcat 7日志记录文档以获取更多信息。此处显示的示例 logging.properties
文件使用 FINE
而不是 DEBUG
:
...
1catalina.org.apache.juli.FileHandler.level = FINE
...
并且还为您提供了设置附加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
