如何將log4j.properties文件的路徑更改爲特定路徑？

我試圖將log4j.properties的文件路徑從/ WEB-INF/classes更改爲/ WEB-INF/lib。有什麼方法可以將其歸檔嗎？我嘗試了上下文參數來設置路徑，但我沒有存檔我的目標。

<context-param> 
    <!-- specifiy <path> to a log4j.properties file to superseed shipped version --> 
    <param-name>LOG4J_PROPERTIES</param-name> 
    <param-value>/lib/log4j.properties</param-value> 
    </context-param>

這些都是從tomcat7-stdout.2015-04-01.log輸出

我還試圖用一個監聽器：

<listener> 
<listener-class>com.company.ecm.appsrv.logging.impl.LoggingSetup</listener-class> 
</listener>

，但不似乎改變了一切。

LoggingSetup.java：

package com.company.ecm.appsrv.logging.impl; 

import java.io.IOException; 
import java.io.InputStream; 
import java.util.Properties; 

import javax.servlet.ServletContext; 
import javax.servlet.ServletContextEvent; 
import javax.servlet.ServletContextListener; 

import org.apache.log4j.Logger; 
import org.apache.log4j.PropertyConfigurator; 

public class LoggingSetup 
implements ServletContextListener 
{ 
    @Override 
    public void contextDestroyed(ServletContextEvent sce) 
    { 
     // Nope 
    } 

    @Override 
    public void contextInitialized(ServletContextEvent sce) 
    { 
     ServletContext sctx = sce.getServletContext(); 
     Properties props = new Properties(); 
     InputStream ins = null; 

     try 
     { 
      ins = sctx.getResourceAsStream("/WEB-INF/lib/log4j.properties"); 
      if(ins == null) 
       throw new RuntimeException("Could not find log4j properties"); 
      props.load(ins); 
      String ctxName = sctx.getContextPath().substring(1); 
      props.put("contextname", ctxName); 
      PropertyConfigurator.configure(props); 
      Logger.getRootLogger().info("Loggin set up."); 
     } 
     catch(IOException ex) 
     { 
      ex.printStackTrace(); 
      sctx.log("Could not setup logging", ex); 
     } 
     finally 
     { 
      if(ins != null) 
      { 
       try { ins.close(); } catch(IOException ex) { /* ignored */ } 
      } 
     } 
    } 
}

設置以下上下文PARAM：

<context-param> 
    <param-name>log4jConfigLocation</param-name> 
    <param-value>/WEB-INF/config/log4j/log4j.properties</param-value> 
    </context-param>

不要忘記添加

<listener> 
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> 
    </listener>

in web.xml

由於某種原因，執行後，我得到了404錯誤。我的服務已部署，但無法使用您的解決方案：| – Aebian 2015-04-01 09:02:02

問題腸固定。我剛剛搞砸了Java代碼，這次我的主管回到了辦公室，幫助了我。謝謝你的幫助vijay。
