为什么我的tomcat找不到log4j.properties文件？

Question

我有一个带有和ant构建的servlet。我产生了战争并将其部署在tomcat中，一切似乎都很好，但是当我尝试通过GET调用服务时，出现以下错误：

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

我看不到这里会发生什么。

这是我的tomcat文件夹的结构：

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

蚂蚁构建文件如下所示：

<?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"/>

    </copy>
    <copy todir="${target.home}/${app.name}/WEB-INF/classes">

    </javac>
</target>

<target name="dist" depends="compile"
    description="Create WAR file for binary distribution">

我已经尝试将log4j.properties放在相同级别的web.xml中，并且遇到相同的错误。
