二、搭建Struts框架
1、引入依赖
2、在web.xml中配置核心入口（filter）

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_4_0.xsd"
         version="3.0">

    <filter>
        <filter-name>struts2filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
        filter-class>
    filter>
    <filter-mapping>
        <filter-name>struts2filter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>
web-app>

3、在scr/main/resources下创建struts.xml

DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">
<struts>
    
    <constant name="struts.action.extension" value="action,do,,"/>

    <package name="dmc" extends="struts-default">
        
    package>
struts>

三：搭建spring框架
1、引入依赖
2、创建application.xml文件，建议在scr/main/resources下

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       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/aop 
      http://www.springframework.org/schema/beans/spring-aop.xsd
        http://www.springframework.org/schema/tx 
      http://www.springframework.org/schema/beans/spring-tx.xsd
        http://www.springframework.org/schema/context  
      http://www.springframework.org/schema/beans/spring-context.xsd">

beans>

四：SS整合
所谓的ssh整合就是将sturts的action交给spring管理，原来action有sturts自己创建，随着struts2-spring-plugin整合插件包的引入，告诉sturts现在改为向Spring要action

1、引入依赖
2、在web.xml中配置监听器，在服务器启动时，就启动spring框架，确保比struts启动的早

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_4_0.xsd"
         version="3.0">
    
    <filter>
        <filter-name>struts2filter-name>
        <filter-class>
            org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter
        filter-class>
    filter>
    <filter-mapping>
        <filter-name>struts2filter-name>
        <url-pattern>/*url-pattern>
    filter-mapping>
    
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListenerlistener-class>
    listener>
web-app>

再提供一个全局参数，指定spring配置文件

<context-param>
        <param-name>contextConfigLocationparam-name>
        <param-value>classpath:application.xmlparam-value>
    context-param>

五：搭建hibernate
1、scr/main/resources下创建hibernate.cfg.xml

DOCTYPE hibernate-configuration  PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        
        
        <property name="hibernate.show_sql">trueproperty>
        
        <property name="hibernate.format_sql">trueproperty>
        
        <property name="hibernate.hbm2ddl.auto">updateproperty>
        
        <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialectproperty>
    session-factory>
hibernate-configuration>

2、封装hibernateUtil，管理sessionFactory工厂

package com.hibernate.util;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.boot.registry.StandardServiceRegistry;
import org.hibernate.boot.registry.StandardServiceRegistryBuilder;
import org.hibernate.cfg.Configuration;

/**
 * @author PGG
 */
public class HibernateUtil {
    private static SessionFactory factory;
    static {

        //方式一：
       /* Configuration cfg=new Configuration();
        cfg.configure();
        SessionFactory factory=cfg.buildSessionFactory();
        */

        //方式二
        StandardServiceRegistry r = new StandardServiceRegistryBuilder().configure().build();
        Configuration cfg=new Configuration();
        factory=cfg.buildSessionFactory(r);
    }
    /**
     * 获取session对象
     * @return
     */
    public static Session getSession(){
        return factory.openSession();
    }
}

注意：因为后面要实现sh整合，sh整合后，spring负责管理hibernatede 数据源，工厂，事务，所以配置文件中不需要配置数据源信息和hibernate封装了

六：sh整合
所谓的ss整合，就是由spring负责管理hibernate数据源，工厂，事务
1、引入依赖
2、实现hibernate整合的配置：管理数据源、管理工厂、管理事务

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:context="http://www.springframework.org/schema/context"
       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/aop
      http://www.springframework.org/schema/beans/spring-aop.xsd
        http://www.springframework.org/schema/tx
      http://www.springframework.org/schema/beans/spring-tx.xsd
        http://www.springframework.org/schema/context
      http://www.springframework.org/schema/beans/spring-context.xsd">
    
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
        <property name="url" value="jdbc:mysql://localhost:3306/hibernate?useUnicode=true"/>
        <property name="username" value="root"/>
        <property name="password" value="123456"/>
    bean>
    
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
        <property name="dataSource" ref="dataSource"/>
    bean>
    
    <bean id="manager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    bean>
      
    <tx:annotation-driven transaction-manager="manager"/>
beans>

事务管理又分为三个点：
事务管理者（谁管理事务）

 <bean id="manager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    bean>

事务策略（如何管理事务）
事务切入点（什么时候管理事务）
注意：事务策略和事务切入点可以使用注解

  
    <tx:annotation-driven transaction-manager="manager"/>

注意：sh整合时，对dao的操作也有影响：因为.原来dao与数据库交互时，使用我们自己管理的工厂获得session对象
现在：sh整合后，需要使用spring管理的工厂获得session对象

dao继承父类hibernateDaoSupport，然后为Dao的父类注入SessionFactory工厂，在方法中，通过父类方法获得hibernate操作的模板对象super.getHIbernateTemplate，该模板提供了crud方法

SSH框架的应用

1、创建包结构，功能类，实现orm,实现IOC,DI,excel文件
注意：在application.xml文件中，开启spring,IOC DI的注解编程

 
    <context:component-scan base-package="com.hibernate.action,com.hibernate.service,com.hibernate.dao"/>

注意：sh整合后，dao需要到spring管理的sessionFactory中获得session对象，1：dao继承HIbernateDaoSupport 为dao（父类）注入SessionFactory（曲线救国的方式）

@Repository
public class CarDao extends HibernateDaoSupport {
    /**
     * 采用曲线救国的方式为为dao（父类）注入SessionFactory
     * @param factory
     */
    @Autowired
    public void setFactory (SessionFactory factory){
        super.setSessionFactory(factory);
    }
}

2、设计网页，选择文件上传

<html>
<body>
    <form action="upload.do" method="get" enctype="multipart/form-data">
        <input type="file" name="excel"/><br/>
        <button>按钮button>
    form>
body>
html>

3、action处理请求（接收文件，读取excel，实现批量保存）
注意：
action注解实现的请求映射

 @Action(value="upload")
    public void upload(){
        //poi读取excel文件

    }

注意：struts文件上传

    private File excel;
    public void setExcel(File excel){
        this.excel=excel;
    }

注意：poi读取excel文件

 /**
     *  @Action表示接收的时upload的请求
     */
    @Action(value="upload")
    public void upload() throws IOException {
        List<Car> cars=new ArrayList<>();
        //poi读取excel文件
        Workbook book= WorkbookFactory.create(excel);
        Sheet sheet=book.getSheetAt(0);
        for(int i=1;i<=sheet.getLastRowNum();i++){
            //获取行
            Row r=sheet.getRow(i);
            //获取列的单元格
            Cell c1 = r.getCell(0);
            Cell c2 = r.getCell(1);
            Cell c3 = r.getCell(2);
            Cell c4 = r.getCell(3);
            int cno=(int)c1.getNumericCellValue();
            String cname=c2.getStringCellValue();
            String color=c3.getStringCellValue();
            int price=(int)c4.getNumericCellValue();
            Car car=new Car(cno,cname,color,price);
            cars.add(car);
        }
        //批量保存
        carService.saves(cars);
        //直接响应
        ServletActionContext.getResponse().getWriter().write("上传成功");
    }

注意：service实现批量保存的方法需要指定事务

 /**
     * 批量保存
     * @param cars
     */
    @Transactional(isolation= Isolation.SERIALIZABLE,propagation= Propagation.REQUIRED,rollbackFor=Exception.class)
    public void saves(List<Car> cars){
        //循环保存
        for(Car car:cars){
            carDao.save(car);
        }
    }
