在Log4J中限制消息长度 [英] Limit message length in Log4J

问题描述

我正在开发一个使用Log4J进行日志记录的应用程序.有时，该应用程序会创建非常长，> 10000个字符的日志消息.当日志显示在Eclipse的控制台"窗口中时，这会导致性能问题.

I'm working on an application that uses Log4J for logging. Occasionally, the application creates log messages that are very long, > 10000 characters. This causes performance problems when the log is displayed in a Console window in Eclipse.

我想限制最大消息长度，将长消息截断为最大长度.我该如何使用Log4J做到这一点?

I want to limit the maximum message length, truncating long messages to the maximum length. How can I do that with Log4J?

推荐答案

您可以使用

You can use a PatternLayout with a ConversionPattern that has a 'maximum width' format modifier on the message conversion character.

示例:

%r [%t] %-5p %c %x - %.10000m%n

将邮件大小限制为10000个字符.

limits message size to 10000 characters.
