SSH整合Demo
SSH 整合 Java Spring Hibernate
SSH的环境搭建，我的流程是：
Spring --> Hibernate --> Spring整合Hibernate --> Struts2 --> Spring整合Struts2
1.开发环境：
IntelliJ IDEA: 2018
Maven :3.0x
Java 8
2.pom.xml

3.web.xml

配置Spring监听器和Strut2过滤器
3.编写Spring配置文件（applicationContext.xml）
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"xmlns:bean="http://www.alibaba.com/schema/stat"xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context.xsdhttp://www.springframework.org/schema/aophttp://www.springframework.org/schema/aop/spring-aop.xsdhttp://www.springframework.org/schema/txhttp://www.springframework.org/schema/tx/spring-tx.xsd http://www.alibaba.com/schema/stat http://www.alibaba.com/schema/stat.xsd"><!--扫描外部配置文件--><context:property-placeholder location="classpath:jdbc.properties"/><!--配置连接池--><!--2.Druid数据池--><bean id="ds" 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整合Spring--><bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"><!--注入连接池--><property name="dataSource" ref="ds"/><property name="hibernateProperties"><props><prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop><prop key="hibernate.show_sql">true</prop><prop key="hibernate.hbm2ddl.auto">update</prop><prop key="hibernate.format_sql">true</prop></props></property><!--配置Hibernate的映射文件--><property name="mappingResources"><list><value>hbm/Product.hbm.xml</value><value>hbm/Department.hbm.xml</value><value>hbm/Employee.hbm.xml</value></list></property><property name="packagesToScan"><list><value>com.koali.pojo</value></list></property></bean><!--Action交给Spring来管理--><bean id="productAction" class="com.koali.action.ProductAction" scope="prototype"><property name="productService" ref="productService"/></bean><bean id="employeeAction" class="com.koali.action.EmployeeAction" scope="prototype"><property name="employeeService" ref="employeeService"/></bean><bean id="departmentAction" class="com.koali.action.DepartmentAction" scope="prototype"><property name="departmentService" ref="departmentService"/></bean><!--配置Service层的类--><bean id="productService" class="com.koali.service.ProductService"><property name="productDao" ref="productDao"/></bean><bean id="employeeService" class="com.koali.service.Impl.EmployeeServiceImpl"><property name="employeeDao" ref="employeeDao"/></bean><bean id="departmentService" class="com.koali.service.Impl.DepartmentServiceImpl"><property name="departmentDao" ref="departmentDao"/></bean><!--配置Dao层的类--><bean id="productDao" class="com.koali.dao.ProductDao"><property name="sessionFactory" ref="sessionFactory"/></bean><bean id="employeeDao" class="com.koali.dao.Impl.EmployeeDaoImpl"><property name="sessionFactory" ref="sessionFactory"/></bean><bean id="departmentDao" class="com.koali.dao.Impl.DepartmentDaoImpl"><property name="sessionFactory" ref="sessionFactory"/></bean><!--配置事务管理--><bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"/></bean><!--开启事务注解--><tx:annotation-driven transaction-manager="transactionManager"/></beans>
4.编写Strut2的配置文件（strut.xml）
<?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><package name="ssh" extends="struts-default" namespace="/"><!-- <action name="product_*" class="productAction" method="{1}"></action>--><action name="employee_*" class="employeeAction" method="{1}"><result name="input">/index.jsp</result><result name="success" type="redirect">/frame.jsp</result><result name="findAll">/jsp/employee/list.jsp</result><result name="saveUI">/jsp/employee/add.jsp</result><result name="saveSuccess" type="redirectAction">employee_findAll.action</result><result name="editSuccess">/jsp/employee/edit.jsp</result><result name="updateSuccess" type="redirectAction">employee_findAll.action</result><result name="deleteSuccess" type="redirectAction">employee_findAll.action</result></action><action name="department_*" class="departmentAction" method="{1}"><result name="findAll">/jsp/department/list.jsp</result><result name="saveUI">/jsp/department/add.jsp</result><result name="saveSuccess" type="redirectAction">department_findAll.action</result><result name="editSuccess">/jsp/department/edit.jsp</result><result name="updateSuccess" type="redirectAction">department_findAll.action</result><result name="deleteSuccess" type="redirectAction">department_findAll.action</result></action></package></struts>
5.最后编写简单的代码看看是否搭建成功
6.测试效果：
成功提交后，经过了action，service，dao，后台成功输出。
7.数据库
