1.首先建立maven-webapp项目，选择如下选项，

点击NEXT，填写项目信息，之后默认next，直至finish

 项目建好后，项目结构如下:

可在main目录下手动建立项目所需目录，如下:

并右键点击Java文件夹，标记为:(Sources root 文件夹用来存放Java class文件，若不标记，在new文件时没有Java class选项)

并右键点击resources文件夹，标记为:（Resources Root用来存放资源文件，如XML，properties之类的）

标记后目录如下:

2.在POM.xml里添加依赖（不用maven时其实就是导入jar包），所需的各种依赖可去https://mvnrepository.com/找得。

pom.xml添加依赖后如图(这是我个人添加的依赖，也可以根据自己的需要去上面链接找寻依赖，在pom.xml添加依赖后，会自动从网上下载相关jar包存放在external libraries里，无需自己导入jar包)：

3.在resources文件夹下建好spring配置文件 applicationContext.xml

4.在resources文件夹下建好struts配置文件 struts.xml

5.在web.xml里配置spring和struts

<!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 version="2.5"
         xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">


  <display-name>Archetype Created Web Application</display-name>

  <!--Spring 的框架的核心监听器-->
  <!--来自spring-web依赖-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!--spring配置文件的位置-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>


  <!--Struts2的框架的核心过滤器的配置-->
  <filter>
    <filter-name>struts</filter-name>
    <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

    <!--struts.xml文件的位置 -->
    <init-param>
      <param-name>config</param-name>
      <param-value>struts.xml</param-value>
    </init-param>
  </filter>

  <!--对所有用户请求进行过滤-->
  <filter-mapping>
    <filter-name>struts</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>



</web-app>

6.完善struts的配置

1)新建一个JSP，建立表单

<%@taglib uri="/struts-tags" prefix="s"%>
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h1>保存信息</h1>
<s:form action="info_save" namespace="/" method="POST" theme="simple">
    <table border="1" width="400">
        <tr>
            <td>名称</td>
            <td><s:textfield name="name"></s:textfield> </td>
        </tr>
        <tr>
            <td>描述</td>
            <td><s:textfield name="description"></s:textfield> </td>
        </tr>
        <tr>
            <td colspan="2"><input type="submit" value="保存"></td>
        </tr>
    </table>
</s:form>
</body>
</html>

2）在Java文件夹下建立包结构以及相关类

Info类

public class Info {

    private Integer pid;

    private String name;

    private String description;

    public Integer getPid() {
        return pid;
    }

    public void setPid(Integer pid) {
        this.pid = pid;
    }

    public String getName() {
        return name;
    }

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

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    @Override
    public String toString() {
        return "Info{" +
                "name='" + name + '\'' +
                ", description='" + description + '\'' +
                '}';
    }
}

InfoAction类(这里利用modelDriven接口将JSP表单里的数据传递到Info类中)

public class InfoAction extends ActionSupport implements ModelDriven<Info> {

    private Info info = new Info();

    private InfoService infoService;

    public void setInfoService(InfoService infoService) {
        this.infoService = infoService;
    }

    @Override
    public Info getModel() {
        return info;
    }

    public void save(){
        System.out.println("action.....");
        infoService.save(info);
    }
}

InfoService类

public class InfoService {

    private InfoDao infoDao;

    public void setInfoDao(InfoDao infoDao) {
        this.infoDao = infoDao;
    }

    public void save(Info info){
        System.out.println("service...");
        infoDao.save(info);
    }
}

InfoDao类

public class InfoDao {

    public void save(Info info){
        System.out.println("dao.......");
        System.out.println(info.toString());
    }
}

3)在struts.xml文件中配置数据交互

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>

    <!--struts的前后端交互路径设置-->
    <package name="ssh" extends="struts-default" namespace="/">
        <!--如JSP里 action指定为info_save则是指到action.InfoAction类中去找寻save方法 -->
        <action name="info_*" class="action.InfoAction" method="{1}"></action>

    </package>

</struts>

7.在applicationContext.xml文件中将spring与struts整合，即配置bean

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       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">


    <!--配置业务Service类-->
    <bean id="infoService" class="service.InfoService">
         <property name="infoDao" ref="infoDao"/>
    </bean>

    <!--配置DAO类-->
    <bean id="infoDao" class="dao.InfoDao"></bean>

</beans>

8.配置好tomcat容器，运行JSP页面，报错：

解决措施，在web.xml中将

<!--Struts2的框架的核心过滤器的配置-->
<filter>
  <filter-name>struts</filter-name>
  <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

  <!--struts.xml文件的位置 -->
  <init-param>
    <param-name>config</param-name>
    <param-value>struts.xml</param-value>
  </init-param>
</filter>

改为：

 <!--Struts2的框架的核心过滤器的配置-->
  <filter>
  <filter-name>struts</filter-name>
  <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>

    <!--struts.xml文件的位置 -->
    <!--需要注意的是，若不加上struts-default.xml,struts-plugin.xml,会报错,
        没有找到依赖配置文件com.opensymphony.xwork2.ObjectFactory。-->

      <param-name>config</param-name>
      <param-value>struts-default.xml,struts-plugin.xml,struts.xml</param-value>
    </init-param>
</filter>

再次运行strutsDemo.jsp页面

点击保存：

后台输出：

至此spring和struts整合完成

9.利用mysql建立数据库sshdemo(暂不需要建表，hibernate映射文件会自动建表)

10.在resources文件夹下，建立jdbc.properties文件用来设置jdbc连接信息

11.在resources文件夹下，建立info.hbm.xml文件来设置类-表映射

info.hbm.xml：

<?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">

<!--类-表的映射文件-->
<hibernate-mapping>
    <class name="domain.Info" table="info">

        <!--主键-->
        <id name="pid" column="pid">
            <generator class="native"></generator>
        </id>

        <property name="name" column="name" length="20"></property>
        <property name="description" column="description"></property>
    </class>
</hibernate-mapping>

12.在applicationContext.xml文件中将spring与hibernate整合

    <!--配置hibernate的相关属性-->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">

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

    <!--开启注解事务-->
    <!--开启之后才可在相应类上添加@Transaction注解-->
    <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>


</beans>

13.修改InfoDao类

public class InfoDao extends HibernateDaoSupport {


    /*
    在HibernateDaoSupport里有这个函数，在applicationContext.xml文件里对InfoDao注入了sessionFactory
    注入之后就自动生成了hibernateTemplate，故下面save函数可以直接使用
    *  public final void setSessionFactory(SessionFactory sessionFactory) {
        if (this.hibernateTemplate == null || sessionFactory != this.hibernateTemplate.getSessionFactory()) {
            this.hibernateTemplate = this.createHibernateTemplate(sessionFactory);
        }

    }
    * */

    public void save(Info info){

        this.getHibernateTemplate().save(info);
        System.out.println("dao……");
    }
}

14.在InfoService类上加上@Transactional注解

@Transactional
public class InfoService {

    private InfoDao infoDao;

    public void setInfoDao(InfoDao infoDao) {
        this.infoDao = infoDao;
    }

    public void save(Info info){
        System.out.println("service...");
        infoDao.save(info);
    }
}
 

15.运行tomcat，打开jsp界面 ，填写表单

后台输出如下

数据库数据如下:

至此，SSH整合完成。
