在logging.properties中自定义日志格式 [英] Customizing log format in logging.properties

问题描述

我在Tomcat 7中配置日志格式需要一些指导。我在日志记录配置方面比较新，所以请原谅幽默这个问题，如果看起来有点基础......

I need some direction in configuring the log format in Tomcat 7. I am relatively new at logging configurations so please excuse humor this questions if it seems a bit basic...

在logging.properties中配置的Tomcat中使用标准日志记录显示以下格式的日志：

Using the standard logging in Tomcat configured in logging.properties displays a log in the format of:

Jun 6, 2011 9:27:00 AM com.class.Control_WS callWebService 
INFO: Response received from Control_WS:[Y]

我想自定义这些日志以压缩到一行，并将日期格式扩展到包括毫秒。

I would like to customize these logs to compress on to one line as well as expanding the date format to include milliseconds.

示例：

[2011-05-04T11:37:00.037|INFO|javax.enterprise.system.stream.out|Response recieved from Control_WS:[Y]]

这是我可以用JUL做的事情还是我需要切换到LOG4J？

Is that something I can do using the JUL or do I need to switch to LOG4J?

任何可以提供的简单示例或方向都会非常感激。

Any simple examples that can be provided or direction would be much appreciated.

推荐答案

如果您使用的是Java 7（或更高版本:-)），则无需再为<$创建自定义格式化程序类c $ c> java.util.logging （JUL）。在Java 7中有一个新属性， java.util.logging.SimpleFormatter.format ，它控制JUL的 SimpleFormatter 打印信息。因此，只要您使用的是SimpleFormatter（无论如何都是默认值），那么这将有效。

If you are using Java 7 (or later :-)) you no longer have to create a custom formatter class for java.util.logging (JUL). In Java 7 there's a new property, java.util.logging.SimpleFormatter.format, which controls how JUL's SimpleFormatter prints the information. So as long as you are using SimpleFormatter (which is the default anyway) then this will work.

一些陷阱：

• 确保实际使用Java 7. :-)


• 请务必使用有效的格式字符串。如果静默恢复为默认格式（标准丑陋的双线）您提供的util / logging / SimpleFormatter.html＃formatrel =noreferrer>格式无效。

• Be sure to actually use Java 7. :-)
• Be sure to use a valid format string. JUL will revert silently to the default format (the standard ugly two-liner) if the format you provide is invalid.
