每次我用 maven 编译时，我都会得到以下异常。

log4j:ERROR Either File or DatePattern options are not set for appender [FILE].

我的 log4j.xml 中有这个配置

<?xml version="1.0" encoding="UTF-8"?>
<!-- TOMCAT SERVER FILE -->
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"
    debug="false">

</log4j:configuration>

经过大量搜索后，我总是找到关于权限的相同答案，但在这种情况下没有用。

当我使用绝对路径时它有效。

请帮忙!

谢谢!

编辑:

我正在使用 tomcat 6.0

-bash-3.00$ /opt/tomcat/instances/tomcat-8080/bin/startupDev.sh version
Using CATALINA_BASE:   /opt/tomcat/instances/tomcat-8080
Using CATALINA_HOME:   /opt/tomcat
Using CATALINA_TMPDIR: /opt/tomcat/instances/tomcat-8080/temp
Using JRE_HOME:       /usr/java

最佳答案

${catalina.base} 解析为空字符串。尝试在此处使用其他环境变量或绝对路径:

<param name="File" value="${catalina.base}/logs/jump_page.log" />
