整合Struts2，Hibernate和Spring的一个简单例子

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">先创建一个web项目IntegrationDemo；</span><span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">通过MyEclipse添加Hibernate配置（网上有很多教程，再次不多做赘述）。</span>

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">手动配置Struts2和Spring，只需添加如下包即可：</span>

在src文件夹分别创建applicationContext.xml文件和struts.xml文件；

接着首先编写Bean，如下：

package com.entity;

/**
* Information entity. @author MyEclipse Persistence Tools
*/

public class Information implements java.io.Serializable {

// Fields

private Integer id;
private String name;
private Integer age;

// Constructors

/** default constructor */
public Information() {
}

/** full constructor */
public Information(String name, Integer age) {
this.name = name;
this.age = age;
}

// Property accessors

public Integer getId() {
return this.id;
}

public void setId(Integer id) {
this.id = id;
}

public String getName() {
return this.name;
}

public void setName(String name) {
this.name = name;
}

public Integer getAge() {
return this.age;
}

public void setAge(Integer age) {
this.age = age;
}

}

然后创建mapping.hbm.xml映射文件，内容如下：

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!--
Mapping file autogenerated by MyEclipse Persistence Tools
-->
<hibernate-mapping>
<class name="com.entity.Information" table="information" catalog="person">
<id name="id" type="java.lang.Integer">
<column name="id" />
<generator class="native"></generator>
</id>
<property name="name" type="java.lang.String">
<column name="name" length="32" />
</property>
<property name="age" type="java.lang.Integer">
<column name="age" />
</property>
</class>
</hibernate-mapping>

接着编写DAO层的代码：
package com.dao;

import org.hibernate.Session;
import org.hibernate.Transaction;

import com.entity.Information;
import com.hibernate.HibernateSessionFactory;

public class UserDAO {

public boolean saveInformation(Information information){

Session session= HibernateSessionFactory.getSession();
Transaction tx=null;
try {
tx=session.beginTransaction();
session.save(information);
tx.commit();
System.out.println("操作成功");
System.out.println(information.getName()+"\n"+information.getName());
return true;
} catch (Exception e) {
// TODO: handle exception
System.out.println("操作失败");
return false;
}finally{
session.close();
}
}

}


再接着编写Biz层的代码：
package com.biz;

import com.dao.UserDAO;
import com.entity.Information;

public class UserBiz {
UserDAO userDAO;
public void setUserDAO(UserDAO userDAO){
this.userDAO=userDAO;
}

public boolean saveData(Information information){
return userDAO.saveInformation(information);
}
}


然后编写Action类：
package com.action;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.biz.UserBiz;
import com.entity.Information;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class AddDataAction extends ActionSupport implements ModelDriven<Information>{
private Information information = new Information();

@Override
public Information getModel() {
// TODO Auto-generated method stub
return information;
}

public String execute()throws Exception{

ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
UserBiz userBiz = context.getBean(UserBiz.class);

boolean flag =userBiz.saveData(information);

if(flag){
return SUCCESS;
}else {
return ERROR;
}
}
}

然后配置struts.xml文件，如下所示：
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
<package name="integration" extends="struts-default">
<action name="addData" class="com.action.AddDataAction">
<result name="success">/success.jsp</result>
<result name="error">/error.jsp</result>
</action>
</package>
</struts>

至此，本项目的主要任务已经完成了
接着在编写一个jsp页面，供用户提交想要存储的数据，如下所示：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib uri="/struts-tags" prefix="s" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>

<title>登录界面</title>

</head>

<body>
<center>
<s:label>向数据可表information中添加记录</s:label>
<s:form action="addData">
<s:textfield label="姓名" name="name"></s:textfield>
<s:textfield label="年龄" name="age"></s:textfield>
<s:submit value="提交" align="center"></s:submit>
</s:form>
</center>
</body>
</html>


然后在编写两个Jsp文件，分别表示存储成功的success.jsp和存储失败的error.jsp，非常简单，就不在列出了。
到这里，整合S2SH的项目已经完成了。
