为什么我的 tomcat 找不到 log4j.properties 文件？

Question

我有一个带有 ant 构建的 servlet。 我生成战争并将其部署在我的 tomcat 中，一切似乎都很好，但是当我尝试通过 GET 调用我的服务时，出现以下错误：

log4j:ERROR Could not read configuration file [log4j.properties]

我看不出这里会发生什么。

这是我的 tomcat 文件夹的结构：

WEB-INF
 |- classes
      |- log4j.properties
      |- servletConnector.class
 |- lib
 |- web.xml

ant 构建文件如下所示：

<?xml version="1.0" encoding="UTF-8"?>

<property name="app.name" value="amadeus1"/>
<property name="target.home" value="${basedir}/target"/>
<property name="war.home" value="${basedir}/war"/>
<property name="src.home" value="${basedir}"/>
<property name="webapp.home" value="${basedir}/src/main/webapp"/>
<property name="libs.home" value="${basedir}/lib"/>
<property name="config.home" value="${basedir}/config"/>
<property name="env" value="des"/>

我已经尝试将 log4j.properties 放在 web.xml 的同一级别，我得到了同样的错误。
