说明：<param-value>/WEB-INF/applicationContext-*.xml</param-value>把所有applicationContext-*.xml这种格式的包括进来。

 

struts.xml文件为：

<?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.objectFactory" value="spring"/>
 <constant name="struts.multipart.saveDir" value="/tmp"></constant>
 <include file="struts-default.xml"/>
 
 <package name="admin" extends="struts-default">
  <action name="login" class="loginAction" method="login">
   <result name="success" type="redirect">/admin/index.jsp</result>
   <result name="error">/error.jsp</result>
  </action>
 </package>

</struts>

 

说明：<constant name="struts.objectFactory" value="spring"/>用来表示Struts由spring来管理

 

部分代码：（持久类中必须继承HibernateDaoSupport这个类）

public Admin getAdmin(final String account,final String password){
  Admin admin=null;
  final String hql="from Admin admin where admin.adminAccount=:account and admin.adminPassword=:password";
  /*List list=getHibernateTemplate().find(hql,new Object[]{username,password});
  if(!list.isEmpty()){
   admin=(Admin)list.get(0);
  }
  return admin;*/
  return (Admin)getHibernateTemplate().execute(
    new HibernateCallback(){
     public Object doInHibernate(Session session)throws HibernateException,SQLException{
      Query query=session.createQuery(hql).setString("account",account).setString("password",password);
      return (Admin)query.uniqueResult();
     }
    });
 }

 

注：由set方法注入依赖，因此必须实习get/set方法才可以注入

 

最后就是jsp页面，action调用service，service调用hibernate（持久类）。
