Question

我正在尝试构建一个以WAR项目为模块的Maven EAR项目。当我尝试向其添加log4j时，它无法找到位于Web项目的src / main / java文件夹中的log4j.properties文件。

它给出了以下错误 -

[6/12/15 12:43:26:786 IST] 0000009c SystemOut     O log4j: Trying to find [log4j.properties] using ClassLoader.getSystemResource().
[6/12/15 12:43:26:786 IST] 0000009c SystemOut     O log4j: Could not find resource: [null].

以下是我在web项目中的pom.xml文件

是否有人对可能导致此问题的原因有任何建议？

Answer 1

您的log4j.properties文件应位于资源文件夹中。

尝试将其从src/main/java放到资源文件夹

Log4j无法在maven War项目的Local classpath中包含项目构建目录
