本文介绍了一个关于Struts框架与Spring框架集成时遇到的问题，主要问题是由于没有正确配置ContextLoaderListener导致无法获取到Spring的ApplicationContext上下文。文中详细记录了web.xml配置及BaseAction类的相关代码。

这是我的web.xml配置文件如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<servlet-name>action</servlet-name>

<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>

org.springframework.web.context.ContextLoaderListener
</lister-class>
</lister>

<welcome-file-list>
<welcome-file>use.jsp</welcome-file>
</welcome-file-list>
</web-app>

下面是我的一个baseAction在程序运行后的调用：

package com.test.struts.action;

import org.apache.commons.beanutils.BeanUtils;
import org.apache.struts.actions.DispatchAction;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.web.context.support.WebApplicationContextUtils;

public class BaseAction extends DispatchAction
{
ApplicationContext ur=null;
public BaseAction()
{
super();
}

public void copyProperties(Object to, Object from) throws Exception {
BeanUtils.copyProperties(to, from);
}
public Object getBean(String name)
{
if (ur == null) {
ur = WebApplicationContextUtils.getRequiredWebApplicationContext(servlet.getServletContext());
}
return ur.getBean(name);
}
但是在调用这个方法时就会出现如下错误：

HTTP Status 500 -
