1、新建项目

        使用eclipse快速搭建meaven项目。

2、导入jar包，搭建框架

  pom文件（jar包部分）：

3、配置spring.xml文件，bean有两种方式，这里采用映射文件注入（注解比较简单，因此在这练习映射文件方式）

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd">
    <!-- 开启包扫描，并注册注解 -->
<!--     <context:component-scan base-package="com.ssh.dao"/> -->
<!--     <context:component-scan base-package="com.ssh.dao.Impl"/> -->
<!--     <context:component-scan base-package="com.ssh.service"/> -->
<!--     <context:component-scan base-package="com.ssh.service.Impl"/> -->
    <!-- 引入属性文件 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
          init-method="init" destroy-method="close">
        <!--配置连接池属性-->
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
        <!-- 配置初始化大小、最小、最大 -->
        <property name="initialSize" value="3" />
        <property name="minIdle" value="3" />
        <property name="maxActive" value="20" />
        <!-- 配置获取连接等待超时的时间 -->
        <property name="maxWait" value="60000" />
        <!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
        <property name="timeBetweenEvictionRunsMillis" value="60000" />
        <!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
        <property name="minEvictableIdleTimeMillis" value="300000" />
        <property name="validationQuery" value="SELECT 1" />
        <property name="testWhileIdle" value="true" />
        <property name="testOnBorrow" value="false" />
        <property name="testOnReturn" value="false" />
        <!-- 配置监控统计拦截的filters -->
        <property name="filters" value="stat" />
    </bean>
    <!-- 配置Hibernate的SessionFactory -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!-- 注入连接池 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 配置Hibernate属性 -->
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.show_sql">true</prop><!-- 是否展示SQL -->
                <prop key="hibernate.hbm2ddl.auto">update</prop><!-- 是否自动创建表结构 -->
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</prop>
            </props>
        </property>
        <!-- 扫描并加载注解过的实体类 -->
        <property name="packagesToScan" value="com.ssh.entity"/>
    </bean>
    <!-- 配置事务管理器 -->
<!--     <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"> -->
<!--         注入SessionFactory -->
<!--         <property name="sessionFactory" ref="sessionFactory"/> -->
<!--     </bean> -->
    <!-- 配置事务增强 -->
<!--     <tx:advice id="txAdvice" transaction-manager="transactionManager"> -->
<!--         <tx:attributes> -->
<!--             配置需要进行事务管理的方法，和事务传播行为 -->
<!--             <tx:method name="save*" propagation="REQUIRED"/> -->
<!--             <tx:method name="update*" propagation="REQUIRED"/> -->
<!--             <tx:method name="delete*" propagation="REQUIRED"/> -->
<!--         </tx:attributes> -->
<!--     </tx:advice> -->
   
    <!-- 将action交给spring管理 -->
    <bean id="SayHelloAction" class="com.ssh.action.SayHelloAction" scope="prototype"></bean>
</beans>

4、配置jdbc.propeties

jdbc.url=jdbc:mysql://localhost:3306/ssh?useUnicode=true&characterEncoding=utf-8    （ssh是我的数据库名）
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.username=root    (数据库用户名)
jdbc.password=password （密码）

5、配置web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app 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_3_0.xsd"
         version="3.0">
    <!-- 配置Struts2过滤器 -->
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- 配置Spring的监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 指定Spring配置文件所在路径 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring.xml</param-value>
    </context-param>
</web-app>


6、配置struts.xml文件

<?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>
    <!-- 配置访问页面 -->
    <!-- Struts2在2.5版本后添加strict-method-invocation(严格方法访问)，默认为true，不能使用动态方法调用功能，故需设为false -->
    <package name="product" extends="struts-default" namespace="/"
        strict-method-invocation="false">
        <action name="say" class="SayHelloAction">
            <result>/index.jsp</result>
            <result name="success">/index.jsp</result>
        </action>
    </package>

</struts>

7、编写SayHelloAction.java文件

package com.ssh.action;
import com.opensymphony.xwork2.ActionSupport;
/**
* @ClassName: sayHello
* @Description: TODO
* @author HRX
* @date 2018年7月9日 下午10:27:17
* 
*/
public class SayHelloAction extends ActionSupport{
// private static final String SUCCESS = "SUCCESS";
 
 public String say(){
  System.out.println("Hello my first ssh!!");
  return SUCCESS;
 }
}

8、编写index页

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="/struts-tags" prefix="s" %>
<html>
<body>
<h2>第一个ssh项目！！！</h2>
</body>
</html>

9、测试

地址：http://localhost:8080/SSHTest/say.action
