SSI框架搭建相关问题

在实验室写了两年代码，框架用过好几个，但是一般都是实验室使用的比较成熟的框架，不需要自己去搭建，只需要往里面写代码就是了，因此到现在框架的搭建对于我来说，还是一件比较陌生的事情，虽然之前的框架在使用的时候都会看一下它的配置，但是真正自己搭建的时候还是遇到了很多问题。
我在网上找了一个比较详细的SSI框架搭建的教程，开始按照上面的步骤一点一点的开始做，可以说是完全按照上面的内容来的，但是等搭完以后一运行，果然是不行的，因此开始了我漫长的调试阶段。
我遇到的第一个问题，是由于我之前正在使用另一个工具调试项目，因此8080端口被占用，换了一个端口号仍然不行，最后还是结束掉那个进程才得以解决。
下面是第二个问题：
问题就出在红色位置的那一行，我查了一下其他的配置SSI框架的教程，发现很多都没有这一句，因此我尝试把它注掉，运行，没想到竟然没有问题了，真是意外惊喜，我查了下，这是一个struts的拦截器，但是为什么这里错了，我还没有搞清楚。
当我在下面添加了 <default-class-ref class="com.opensymphony.xwork2.ActionSupport"/>以后运行不再有错，需要查看相关书籍确定一下。
下面是我的整个框架的配置：
首先是项目的整体的结构图：
Login.java
User.java
user.xml
IUserDao.java
UserDao.java
IUserService.java
UserService.java
sqlMapConfig.xml
struts.properties
struts.xml
web.xml
jar包中可能有没有使用到的，还待进一步的缩减。

This is very likely to create a memory leak.这个问题真是让我纠结了半天，我在网上查到了有关这个问题的解决方案，是由于jar包的问题，但是当我按照解决方法重新导入jar包以后，问题依然存在，既然没有找到适合的解决方法，我只能自己来试一下，根据出错的信息，我定位到struts2.xml文件下面先把struts2.xml贴出来：
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.objectTypeDeterminer" value="notiger" /> <constant name="struts.objectFactory.spring.autoWire" value="name" /> <constant name="struts.objectFactory" value="spring" /> <package name="struts2" extends="struts-default"> <default-interceptor-ref name="paramsPrepareParamsStack"/> <default-class-ref class="com.opensymphony.xwork2.ActionSupport"/> <action name="login" class="LoginAction"> <result name="success">/success.jsp</result> <result name="input">/login.jsp</result> </action> </package> <include file="com/zhouqian/bean/user.xml" /> </struts>
