一、引入pom 依赖节点：

            <scope>test</scope>
        </dependency>

    </dependencies>

</project>

二、在web.xml中添加核心过滤器以及监听器：

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <!--有点东西-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <filter>
    <filter-name>struts</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>


  <!--1.监听器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
</web-app>

三、构建分层： 1. 首先创建 dao 层（这里只做添加操作）

package cn.happy.dao;

import cn.happy.bean.Dept;

/**
 * Created by Happy on 2017-10-11.
 */
public interface IDeptDAO {
    // 添加部门方法
    public void addDept(Dept dept);


}

其次，dao层实现类：

package cn.happy.dao;

import cn.happy.bean.Dept;
import org.hibernate.Session;
import org.hibernate.SessionFactory;


/**
 *
 */

public class DeptDAOImpl implements IDeptDAO {

    private SessionFactory sessionFactory;

    public void addDept(Dept dept) {
        Session session = sessionFactory.getCurrentSession();
        session.save(dept);
    }

    public SessionFactory getSessionFactory() {
        return sessionFactory;
    }

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

2. 接下来是实体层 bean 以及关联配置文件：

package cn.happy.bean;


/**
 *
 */

public class Dept {

    private Integer deptno;

    private String deptname;

    public Integer getDeptno() {
        return deptno;
    }

    public void setDeptno(Integer deptno) {
        this.deptno = deptno;
    }

    public String getDeptname() {
        return deptname;
    }

    public void setDeptname(String deptname) {
        this.deptname = deptname;
    }
}

配置文件：

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="cn.happy.bean">
    <class name="Dept" table="Dept" schema="huohuo01">
        <id name="deptno" column="deptno">
            <generator class="native"></generator>
        </id>
        <property name="deptname" />
    </class>
</hibernate-mapping>

3. service 层以及实现类：

package cn.happy.service;

import cn.happy.bean.Dept;

/**
 *
 */
public interface IDeptService {
    public void addDept(Dept dept);
}

实现类：

package cn.happy.service;

import cn.happy.bean.Dept;
import cn.happy.dao.IDeptDAO;
import org.springframework.transaction.annotation.Transactional;

/**
 *
 */

public class DeptServiceImpl implements IDeptService {
    private IDeptDAO dao;

    @Transactional
    public void addDept(Dept dept) {
        dao.addDept(dept);
    }


    public IDeptDAO getDao() {
        return dao;
    }

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

4 . 搭建主要的action 层：

package cn.happy.action;

import cn.happy.bean.Dept;
import cn.happy.service.IDeptService;
import com.opensymphony.xwork2.ActionSupport;

/**
 * Created by lenovo on 2017/10/29.
 */
public class DeptAction extends ActionSupport {
    private Dept dept;
    private IDeptService service;

    public String add() {
        System.out.println(dept);
        service.addDept(dept);
        return SUCCESS;
    }


    public Dept getDept() {
        return dept;
    }

    public void setDept(Dept dept) {
        this.dept = dept;
    }

    public IDeptService getService() {
        return service;
    }

    public void setService(IDeptService service) {
        this.service = service;
    }
}

四、 jsp 页面的大致布局：

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>添加部门</title>
</head>
<body>
   <form method="post" action="/add">
      部门名称： <input name="dept.deptname"/>
       <input type="submit" value="添加"/>
   </form>
</body>
</html>

-------------

<%@page language="java" pageEncoding="utf-8" isELIgnored="false" %>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
<h2>Add ok!</h2>
</body>
</html>

五、编写applicationContext.xml 配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
     http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context.xsd
     http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd
     http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd
