本文详细介绍了如何将Spring、Struts2和Hibernate进行整合。关键点包括：Struts2的action由Spring管理，Hibernate的SessionFactory通过Spring注入，dao实现类继承HibernateDaoSupport。在web.xml中配置Spring启动，action和dao在配置文件中定义，值对象及映射文件完成数据对象与数据库的关联。通过实例展示了整合后的应用能够正常运行并实现数据持久化。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

总结一下就是：

1.Struts2与Spring相连的是：action不是Struts2框架new 出来的，而是从Spring的xml(applicationContext.xml)配置文件中拿出

2.Spring和Hibernate相通的是：Hibernate的SessionFactory采用Spring注入，同时dao的实现类继承Spring的类(HibernateDaoSupport)

3.其他的进入哪个领域就使用哪个框架

具体解释见代码：

服务器启动查找Spring的配置文件applicationContext.xml

 </beans>

由Spring来new出来bean配置的类

第一个bean：RegAction.java

package cn.hncu.action;

import cn.hncu.dao.CustomerDao;
import cn.hncu.domain.Customer;

import com.opensymphony.xwork2.ActionSupport;

public class RegAction extends ActionSupport{
	private String customerId;
	private String name;
	private String phone;
	
	private CustomerDao dao;

	public RegAction() {
	}

	public String getCustomerId() {
		return customerId;
	}

	public void setCustomerId(String customerId) {
		this.customerId = customerId;
	}

	public String getName() {
		return name;
	}

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

	public String getPhone() {
		return phone;
	}

	public void setPhone(String phone) {
		this.phone = phone;
	}

	public CustomerDao getDao() {
		return dao;
	}

	public void setDao(CustomerDao customerDao) {
		this.dao = customerDao;
	}

	@Override
	public String execute() throws Exception {
		try {
			Customer cus=new Customer();
			cus.setCustomerId(this.getCustomerId());
			cus.setName(this.getName());
			cus.setPhone(this.phone);
			this.getDao().addCustomer(cus);
			return "success";
		} catch (Exception e) {
			return "input";
		}
	}
	
}

第二个bean:CustomerDao.java接口

package cn.hncu.dao;

import cn.hncu.domain.Customer;

public interface CustomerDao {
	public abstract void addCustomer(Customer customer);
}

实现类CustomerDaoJdbc.java

package cn.hncu.dao;

import org.hibernate.Session;
import org.hibernate.Transaction;
import org.springframework.dao.DataAccessException;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import cn.hncu.domain.Customer;

public class CustomerDaoJdbc extends HibernateDaoSupport implements CustomerDao {

	@Override
	public void addCustomer(Customer customer) {
		try {
			System.out.println(customer);
//			Session session=this.getSession();
//			Transaction tr=session.beginTransaction();
//			session.saveOrUpdate(customer);
//			tr.commit();
//			session.close();
			this.getHibernateTemplate().save(customer);
		} catch (DataAccessException e) {
			e.printStackTrace();
		}
	}

}

Hibernate的配置文件hibernate.cfg.xml

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<session-factory>
	<property name="connection.username">hncu</property>
	<property name="connection.url">

	</property>
	<property name="dialect">

	<property name="myeclipse.connection.profile">mysql1</property>
	<property name="connection.password">1234</property>
	<property name="connection.driver_class">
		com.mysql.jdbc.Driver
	</property>
	<mapping resource="cn/hncu/domain/Customer.hib.xml" />

</session-factory>

</hibernate-configuration>

值对象Customer.java

package cn.hncu.domain;

public class Customer {
	private String customerId;
    private String name;
    private String phone;
   public Customer() {
   }
   public Customer(String customerId) {
       this.customerId = customerId;
   }
   public Customer(String customerId, String name, String phone) {
       this.customerId = customerId;
       this.name = name;
       this.phone = phone;
   }
   public String getCustomerId() {
       return this.customerId;
   }
   public void setCustomerId(String customerId) {
       this.customerId = customerId;
   }
   public String getName() {
      return this.name;
   }
   public void setName(String name) {
       this.name = name;
   }
   public String getPhone() {
       return this.phone;
   }
   public void setPhone(String phone) {
       this.phone = phone;
   }
@Override
public String toString() {
	return "Customer [customerId=" + customerId + ", name=" + name + ", phone="
			+ phone + "]";
}
   
}

值对象的映射文件Customer.hib.xml

<?xml version="1.0" encoding="utf-8"?>  
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"  
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 
<hibernate-mapping>
	
	<class name="cn.hncu.domain.Customer" table="customers" catalog="mydb">
		<id name="customerId" type="java.lang.String">
			<column name="customerID" length="8"></column>
			<generator class="assigned"></generator>
		</id>
		 <property name="name" type="java.lang.String">
            <column name="name" length="40" />
        </property>
        <property name="phone" type="java.lang.String">
            <column name="phone" length="16" />
        </property>
	</class>
</hibernate-mapping>

index.jsp

<%@ 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">

  <body>
   		<s:form action="regAction.action" method="post">

   			<s:textfield name="name" label="客户姓名"/>

   			<s:submit value="提交" align="center"></s:submit>
   		</s:form>
  </body>
</html>

index的form表单请求regAction时请求,查找struts.xml

<?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>
	<package name="add" extends="struts-default">
		<action name="regAction" class="cn.hncu.action.RegAction">
			<result name="success">/jsps/success.jsp</result>
			<result name="input">/index.jsp</result>
		</action>
	</package>
</struts>
