S2SH 整合 主要关注struct2
工具：Myeclipse8.5
strcut2+spring2.5+hibernate3.2
最后使用工具需要的包
可能有些包是用不到了，我没有一个一个去尝试。还是有点依赖工具。
dao层和biz层代码就不贴了，都是使用面向接口的变成。以前也熟练使用ssh。
下面贴上action代码和配置文件。
这个是action类。
package com.exam.action;
import com.exam.biz.UserBiz;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport {
private String username;
private String password;
private UserBiz userBiz;
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public void setUserBiz(UserBiz userBiz) {
this.userBiz = userBiz;
}
/**
*
*/
private static final long serialVersionUID = 1L;
public String execute(){
if ("admin".equals(this.username)&&"admin".equals(this.password)) {
return "success"; //这里的返回值指跟struct.xml中配置对应确定返回给那个页面
}else{
return "error";
}
}
}
通过该类大家也可以看到actionForm也在改action中。改action继承actionsupport，并重写execute方法，该方法有唯一的返回值String。
Struct.xml

还有一部比较的关键在web.xml中配置关于struct2和spring的启动

配置了这个才能将strut2和spring配置结合起来使用！
struct1需要在struct配置中配置读取spring文件。现在感觉方便很多了！但是在写的过程中也出现过问题
问题一、
Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListenerorg.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [applicationContext.xml]:
解决方法：我也不知道对不对，但是这样改过之后就不报这个错误了。我在spring配置中的action bean上面加了一个scope="prototype"就不报这个错误了
错误2、
Unable to load configuration. - [unknown location]
解决方法：少了一个Struts-spring-plugin-2.1.8包
错误3、The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter. Struts tags are only usable when the request
has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. - [unknown location]
at org.apache.struts2.views.jsp.TagUtils.getStack(TagUtils.java:60)
at org.apache.struts2.views.jsp.StrutsBodyTagSupport.getStack(StrutsBodyTagSupport.java:44)
解决方法：
1.引入
<%@ taglib prefix="s" uri="/struts-tags" %>
2.在web.xml中未将拦截的*.action改成/*
一般第二种 情况比较多。是没有改WEB.XML中的拦截
错误4、Caused by: java.lang.IllegalStateException: The action name cannot be the same as the action suffix [Action]
解决方法：action类中的包导入错误：
正确的应该导入：import com.opensymphony.xwork2.ActionSupport;
而我导入的是：import org.springframework.web.struts.ActionSupport;
