如何在 Tomcat 中将日志记录级别设置为 DEBUG？

发布于 2024-10-01 01:13:40 字数 5453 浏览 7 评论 0原文

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。 有人能告诉我出了什么问题吗？

I would like to set level logging to DEBUG in tomcat but in console nevertheless only INFO and WARN output.
Could anybody tell me what's wrong?

首先，要使用的级别名称是FINE，而不是DEBUG。让我们假设 DEBUG 实际上是有效的，因为它使以下解释更有意义......

在 Handler 特定属性 部分中，您正在设置这些处理程序的日志记录级别为DEBUG。这意味着处理程序将处理具有 DEBUG 级别或更高级别的任何日志消息。这并不一定意味着任何 DEBUG 消息实际上都会传递给处理程序。

在设施特定属性部分中，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会传递给处理程序。

默认日志记录级别为 INFO，除了设施特定属性 部分中提到的记录器之外，所有记录器都将具有该级别。

如果您想查看所有 FINE 消息，请添加以下内容：

.level = FINE

但是，这将生成大量日志消息。设置代码的日志记录级别可能更有用：

your.package.level = FINE

请参阅 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

Firstly, the level name to use is FINE, not DEBUG. Let's assume for a minute that DEBUG is actually valid, as it makes the following explanation make a bit more sense...

In the Handler specific properties section, you're setting the logging level for those handlers to DEBUG. This means the handlers will handle any log messages with the DEBUG level or higher. It doesn't necessarily mean any DEBUG messages are actually getting passed to the handlers.

In the Facility specific properties section, you're setting the logging level for a few explicitly-named loggers to DEBUG. For those loggers, anything at level DEBUG or above will get passed to the handlers.

The default logging level is INFO, and apart from the loggers mentioned in the Facility specific properties section, all loggers will have that level.

If you want to see all FINE messages, add this:

.level = FINE

However, this will generate a vast quantity of log messages. It's probably more useful to set the logging level for your code:

your.package.level = FINE

See the Tomcat 6/Tomcat 7 logging documentation for more information. The example logging.properties file shown there uses FINE instead of DEBUG:

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

and also gives you examples of setting additional logging levels:

# 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

Tomcat 的 JULI 日志记录级别

SEVERE - 严重故障

警告 - 潜在问题

INFO - 信息性消息

CONFIG - 静态配置消息

FINE - 跟踪消息

FINER - 详细跟踪消息

FINEST - 非常详细的跟踪消息

JULI logging levels for Tomcat

SEVERE - Serious failures

WARNING - Potential problems

INFO - Informational messages

CONFIG - Static configuration messages

FINE - Trace messages

FINER - Detailed trace messages

FINEST - Highly detailed trace messages

除了已经说过的内容（JULI 中的 DEBUG -> FINE、FINER、FINEST）之外，如果您使用 IDE 运行 Tomcat（例如 Eclipse），请注意它将配置存储在与 CATALINA_HOME 不同的路径上，因此您可能需要添加

-Djava.util.logging.config.file="C:\apache-tomcat-9.0.31\conf\logging.properties"

显式设置您的日志记录属性。

更多信息请参见： 哪里可以在 Eclipse 中查看 Tomcat 日志文件？

In addition to what has already been said (DEBUG -> FINE, FINER, FINEST in JULI), in case you're running Tomcat using an IDE, say Eclipse, note that it stores the configuration on a different path than CATALINA_HOME, so you may need to add

-Djava.util.logging.config.file="C:\apache-tomcat-9.0.31\conf\logging.properties"

to explicit set your logging properties.

More on this here: Where can I view Tomcat log files in Eclipse?

如果这里的其他答案不能解决问题，还可以尝试一件事。

Tomcat提供了一些可以被应用程序直接使用的组件。例如，CsrfPreventionFilter。

当在您的应用程序中使用并且没有其他特殊配置（例如自定义日志管理器）时，此过滤器的配置在您的应用程序内部将从WEB-INF/classes/logging.properties<中读取/code> 而不是来自 CATALINA_BASE/conf/logging.properties 中的服务器范围文件。

因此，如果您没有从应用程序中使用的 Tomcat 组件获得 DEBUG/TRACE 输出，请检查应用程序中的此文件，看看它是否包含正确的日志记录配置。

There is one more thing to try if the other answers here are not solving the problem.

Tomcat provides some components that can be used directly by the application. For example, the CsrfPreventionFilter.

When used within your application and no other special configuration such as a custom log manager, the configuration for this Filter when inside your application will be read from WEB-INF/classes/logging.properties and not from the server-wide file in CATALINA_BASE/conf/logging.properties.

So if you are not getting DEBUG/TRACE output from a Tomcat component used from within your application, check this file in your application to see if it contains the correct logging configuration.
