Java 使用log4j-web.jar在web应用程序中配置Log4j2

我试图通过以下教程在我的Web应用程序中配置log4j2。我正在使用glassfish 4.1.1服务器和servlet版本3.1。我可以使用以下配置配置日志功能：

log4j.properties

     # Root logger option
     log4j.rootLogger=INFO, consoleAppender, fileAppender

     # debug level logger
     log4j.logger.kumar.suraj.college.administration.login=DEBUG

     # Redirect log messages to console
     log4j.appender.consoleAppender=org.apache.log4j.ConsoleAppender
     log4j.appender.consoleAppender.Target=System.out
     log4j.appender.consoleAppender.layout=org.apache.log4j.PatternLayout
     log4j.appender.consoleAppender.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

     # Redirect log messages to a log file, support file rolling.
     log4j.appender.fileAppender=org.apache.log4j.DailyRollingFileAppender
     log4j.appender.fileAppender.File=E:\\DEVELOPMENT\\JAVA\\web-logs\\web-college-administration\\applicationLogs.log
     log4j.appender.fileAppender.layout=org.apache.log4j.PatternLayout
     log4j.appender.fileAppender.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

属性文件位于src/main/resources文件夹中

web.xml

        <?xml version="1.0" encoding="UTF-8"?>

                </context-param>is it required

       <!--from where is this class referenced in dependency without web -->

      </servlet>
      <servlet-mapping>
          <servlet-name>loginServlet</servlet-name>
          <url-pattern>/login</url-pattern>
      </servlet-mapping>

      </web-app>

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

log4j的pom.xml依赖关系

    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>

主要的变化是logger变量的初始化和两个导入。rest所有配置保持原样。在本例中，我还能够在log4j-web.jar中找到web.xml中指定的侦听器类。仍然无法使用此配置进行日志记录

有人能帮我一下吗？或者告诉我我做错了什么？

好的，在对我前面提到的链接进行了更多的研究和重新阅读之后，我终于在我的web应用程序中配置了log4j2，现在我得到了预期的日志。现在我想提一下我做错了什么

如链接中所述

如果我使用Servlet3.0或更高版本，我不需要在部署描述符中注册Log4jServletContextListener类，它只需要在Servlet2.5或更低版本中注册。此外，如果遵守log4j2的命名约定，则不需要提供文件位置

另一个代替log4j2.properties的更改现在我使用log4j2.xml作为log4j2中属性文件的格式，与log4j1中使用的格式不同。感谢下面链接中给出的答案，帮助我解决了这个问题

有关当前支持的格式，请参阅链接

下面是我的部署描述符和log4j配置文件现在的外观：
