Question

实际上我正在尝试为我的动态Web项目实现log4j.file。这是我的web.xml

这里我只给出了web.xml代码，仅用于日志文件

的web.xml

<!-- Log File-->

<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener>
  <listener>
    <listener-class>com.ss.logFile.startupListener.StartupListener</listener-class>
  </listener>
  <context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/classes/log4j.properties</param-value>
  </context-param>
</web-app>

log4j.properties

log4j.rootLogger=ERROR, stdout, rollingFile
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n
log4j.appender.rollingFile=org.apache.log4j.RollingFileAppender
log4j.appender.rollingFile.File=WEB-INF/logs/application.log
log4j.appender.rollingFile.MaxFileSize=512KB
log4j.appender.rollingFile.MaxBackupIndex=10
log4j.appender.rollingFile.layout=org.apache.log4j.PatternLayout
log4j.appender.rollingFile.layout.ConversionPattern=%d %p [%c] - %m%n
log4j.appender.rollingFile.Encoding=UTF-8

StartupListener

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
import org.apache.log4j.xml.DOMConfigurator;
@WebServlet("/StartupListener")
public class StartupListener extends HttpServlet implements ServletContextListener {
    private static final long serialVersionUID = 1L;

    public void init(ServletConfig config) throws ServletException {    
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    }
    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
    }
    @Override
    public void contextInitialized(ServletContextEvent sce) {
        java.util.logging.Logger logger = null;
        String log4jFile = sce.getServletContext().getInitParameter("log4jFileName");
        DOMConfigurator.configure(sce.getServletContext().getRealPath(log4jFile));
        logger = LogManager.getLogger(StartupListener.class.getName());
        logger.debug("Loaded: " + log4jFile);   
    }
}

Sir其实我对log4j很新，所以我不知道如何编写log4j.xml文件以及在哪里放置该文件exaclty.Kindly帮我解决这个问题。谢谢你提前

根据您发布的配置。您没有使用xml但属性文件。正如Adam Dyga所说，只要log4j.properties文件在类路径中，它就会被应用程序自动拾取。您不需要显式加载。要设置日志文件的位置，

log4j.appender.rollingFile.file=D:/MyWEBLogs/MyWEB.log

如何为动态Web项目创建log4j.xml文件？
