Question

我正在尝试部署我的应用程序，但它给了我一个错误：未能实例化SLF4J LoggerFactory报告的异常：

我在Maven依赖区有罐子：

weblogic中log4j jar的类路径：

log4j。xml（来自类路径）：

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

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

    <appender name="LOGFILE" class="org.apache.log4j.FileAppender">

        <param name="File"   value="C:\\Work\\KEPLER\\KH_RRM\\log/rrm-web.log" />
        <param name="Append" value="false" />
        <layout class="org.apache.log4j.PatternLayout">
           <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p [%c{1}] %m%n"/>
        </layout>
    </appender>

    <appender name="STDOUT" class="org.apache.log4j.ConsoleAppender">
        <layout class="org.apache.log4j.PatternLayout">
           <param name="ConversionPattern" value=" %d{yyyy-MM-dd HH:mm:ss} [%t] %-5p [%c{1}] %m%n"/>
        </layout>
    </appender>

    <root>
       <priority value ="ALL" />
       <appender-ref ref="STDOUT" />
       <appender-ref ref="LOGFILE" />
    </root>

</log4j:configuration>

我错了什么？我无法想象。。。请帮帮我！谢谢

Answer 1

答案是：我正在部署到Adminserver，但我必须将我的应用程序部署到clustor，因为ServerStart中的类路径和参数设置不仅在Adminserver上有效，而且只在其他服务器上有效。

Answer 2

一般来说，因为这是maven释放的问题，然后附上你的pom.xml（或一部分）。这比附加截图更好：）

您的log4j依赖项提供了作用域，这意味着log4j已经在您的服务器上，不应随应用程序一起安装。
