我有一个在 Jetty 8.0 上运行的应用程序。

我已将 log4j 配置为将日志写入文件。这是配置。

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

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

    <appender name="consoleAppender" class="org.apache.log4j.ConsoleAppender">
        <param name="Threshold" value="DEBUG" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d%-5p  [%c{1}] %m %n" />
        </layout>
    </appender>

    <appender name="fileAppender" class="org.apache.log4j.RollingFileAppender">
        <param name="Threshold" value="INFO" />
        <param name="File" value="someLogFileName.log" />
        <layout class="org.apache.log4j.PatternLayout">
            <param name="ConversionPattern" value="%d%-5p  [%c{1}] %m %n" />
        </layout>
    </appender>

    <logger name="com.somename">
        <level value="debug" />
        <appender-ref ref="consoleAppender" />
        <appender-ref ref="fileAppender" />
    </logger>

</log4j:configuration>

我什至为运行 Jetty 实例的用户设置了权限。

Jetty的日志目录有以下权限：

drwxrwsr-x  2 someuser somegroupuser   4096 Feb 18 05:27 logs

但仍然出现异常。

有人可以指导我如何解决这个问题吗？

您的 log4j 配置未指定将该日志文件写入哪个目录。

改变

<param name="File" value="someLogFileName.log" />

到

<param name="File" value="${jetty.home}/logs/someLogFileName.log" />

在不指定绝对路径的情况下，log4j 会尝试在 java 进程启动的目录中创建文件。我想在你的情况下它是码头之家。

您可以定义系统属性来更改此行为：

  • 通过代码，确保它在 log4j 初始化之前运行

    System.setProperty("WORKDIR", WORKDIR);

  • 通过命令行

    java -DWORKDIR=WORKDIR

在 log4j 配置中使用此系统属性：

  <param name="File" value="${WORKDIR}/someLogFileName.log" />
