xml - tomcat7-maven-plugin log4j : no appender could be found for logger (org. apache.catalina.startup.Catalina)

Question

我无法初始化 log4j catalina 日志附加器 - 你知道我缺少什么吗？我知道这是一个基本问题，但我坚持这一点。我为 catalina 记录器添加了 org.apache.log4j.net.SyslogAppender 定义，但没有成功。

log4j:WARN 找不到记录器的附加程序 (org.apache.catalina.startup.Catalina) log4j:WARN 请正确初始化log4j系统

---

据我所知，我使用 log4j.xml 初始化 log4j 系统——我做错了什么？同样，我知道这是一个基本问题。这是我的 /src/main/resources/log4j.xml 文件。

这是 tomcat7-maven-plugin 的配置，我知道它很大，对于所需的配置量我深表歉意:

当我手动指定 log4j.xml 文件的位置时，日志记录工作正常。

$ mvn tomcat7:run -DskipTomcat=false -Dlog4j.configuration=file:src/main/resources/log4j.xml

有什么明显的突出之处吗？

Answer 1

您可以将 log4j.properties 或 XML 添加到 systemProperties 部分:

像这样

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <configuration>
        <port>8080</port>
        <path>/</path>
        <systemProperties>
            <log4j.configuration>file:src/main/resources/log4j.properties</log4j.configuration>
        </systemProperties>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.17</version>
        </dependency>
    </dependencies>
</plugin>
