我想通过以下一些教程在我的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。我可以用下面的配置来配置日志记录功能：使用log4j-web.jar在Web应用程序中配置Log4j2
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
属性文件放置在的src/main/resources文件夹
的web.xml
<?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">
<display-name>College Administration</display-name>
<!-- <context-param>
<param-name>log4jConfiguration</param-name>
<param-value>/log4j.properties</param-value>
</context-param>is it required
-->
<!--from where is this class referenced in dependency without web -->
<listener>
<listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
</listener>
<servlet>
<servlet-name>loginServlet</servlet-name>
<servlet-class>kumar.suraj.college.administration.login.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>loginServlet</servlet-name>
<url-pattern>/login</url-pattern>
</servlet-mapping>
</web-app>
定义文件位置的上下文参数被注释掉了。可能log4j默认为名称为log4j.properties的文件。然而，只是想知道它是否指定文件位置的正确方法。
另外我不确定从哪个jar被引用的org.apache.logging.log4j.web.Log4jServletContextListener。我搜索了所有的jar文件，但找不到这个类。对log4j的
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
这一切
LoginServlet.java
package kumar.suraj.college.administration.login;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
import kumar.suraj.college.administration.adduser.AddUserServlet;
public class LoginServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
// final static Logger logger = LogManager.getLogger(LoginServlet.class);
final static Logger logger = Logger.getLogger(LoginServlet.class);
public LoginServlet() {
super();
}
@Override
protected void doGet(final HttpServletRequest request, final HttpServletResponse response)
throws ServletException, IOException {
LoginServlet.logger.debug("debug level logging supported"); response.getWriter().append("Servedat:").append(request.getContextPath());
response.getWriter().append("Hello Suraj");
}
@Override
protected void doPost(final HttpServletRequest request, final HttpServletResponse response) throws ServletException, IOException {
LoginServlet.logger.debug("debug level logging supported");
this.doGet(request, response);
}
}
的pom.xml依赖工作正常，我在这两个控制台获取日志，以及文件。但是，当我试图更改配置按以下链接：
https://logging.apache.org/log4j/2.x/manual/webapp.html#Servlet-3.0 https://logging.apache.org/log4j/2.x/maven-artifacts.html
等代替指定的依赖项前，我切换到
<dependency>
<groupId>org.apache.logging.log4j</groupId>
<artifactId>log4j-web</artifactId>
<version>2.6.2</version>
</dependency>
的log4j的API和log4j的核心是增加作为与log4j-web.jar的传递依赖关系
我在LoginServlet.java中所做的其他更改是因为编译时间错误，我在切换到的log4j-web.jar其是如下：
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
public class LoginServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
final static Logger logger = LogManager.getLogger(LoginServlet.class);
// final static Logger logger = Logger.getLogger(LoginServlet.class);
主要变化在记录器变量的初始化和两个进口。保持所有配置保持原样。在这种情况下，我还能找到log4j-web.jar中web.xml中指定的侦听器类。仍然日志记录不适用于此配置。
有人可以帮我一下，或者告诉我我在做什么错了吗？
