Spring WebFlow項目。 我無法從打印調試語句中停止log4j

Question

我正在從事Spring WebFlow項目。 我無法從打印調試語句中停止log4j。 有人可以告訴我如何獲取它以停止在控制台上放置調試語句並記錄日志。

在服務器啟動時，我看到此警告：

log4j:WARN Continuable parsing error 42 and column 11
log4j:WARN The content of element type "logger" must match "(level?,appender-ref*)".

以下是我的log4j.xml文件：

Answer 1

這只是一個log4j問題。 看來<priority>不是記錄器元素<root>的有效子元素。 相反，您應該改為<level> 。
