SSH整合

    项目整体架构：

        

     SSH整合步骤：

   1.找jar包

   2.建立source 文件夹:resource

   3.在resource里面建立applicationContext.xml

        导入头文件：spring-beans--->factory ---> xml ---->spring-beans-4.0.xsd        

<?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"></beans>

  4.配置数据库文件：jdbc.properties  

connection.driver_class com.mysql.jdbc.Driverconnection.url jdbc:mysql://127.0.0.1:3306/mydbconnection.username rootconnection.password 123456hibernate.dialect org.hibernate.dialect.MySQLDialecthibernate.show_sql truehibernate.format_sql truehibernate.hbm2ddl.auto update

5.装载数据源属性文件：

    spring-beans-->factory ---> config---->PropertyPlaceholderConfigurer

<!-- 装载数据源属性文件 -->     <bean class = "org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">         <property name="location" value="jdbc.properties"/>     </bean>

  

6.配置数据源

   spring-jdbc--->org.springframework.jdbc--->datasource--->DriverManagerDataSource

<!-- 配置数据源 -->    <bean id = "myDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"><!-- 使用属性注入 -->    <property name="driverClassName" value="${connection.driver_class}"/>    <property name="url" value="${connection.url}"/>    <property name="username" value="${connection.username}"/>    <property name="password" value="${connection.password}"/>   </bean>

 

7.整合hibernate的sessionFactory到spring容器管理

   spring-orm--->org.springframework.orm--->hibernate4---->LocalSessionFactoryBean

  建立hibernate的映射文件：hbm/Book.hbm.xml,Student.hbm.xml

    为Book.hbm.xml,Student.hbm.xml配置头文件：

        在hibernate-core--->org.hibernate--->hibernate-mapping-3.0.dtd

Book.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"><hibernate-mapping package="com.xkf.ssh.entity">    <class name = "Book" table = "book">       <id name = "bookId" column="bookId">          <generator class="native"/>       </id>       <property name="bookName"/>       <property name="bookPrice"/>       <many-to-one name="student" column="stuId"/>    </class></hibernate-mapping>

Student.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"><hibernate-mapping package="com.xkf.ssh.entity">   <class name="Student" table="student">      <id name="stuId" column="stuId">         <generator class="native"/>      </id>      <property name="stuName"/>      <property name="stuPass"/>      <property name="stuAge"/>      <set name="books" inverse="true">         <key column="bookId"/>         <one-to-many class="Book"/>      </set>   </class></hibernate-mapping>

找到property的name属性为mappingLocations：spring-orm---->org.springframework.orm---->hibernate4--->LocalSessionFactoryBean---->mappingLocations 

 找到property的name属性为:hibernateProperties：spring-orm---->org.springframework.orm---->hibernate4--->LocalSessionFactoryBean---->hibernateProperties

<!-- 整合hibernate的sessionFactory到spring容器管理 --><bean id = "mySessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">   <!-- 注入数据源 -->  <property name="dataSource" ref="myDataSource"/> <!-- 整合hibernate的hbm.xml文件到SessionFactory对象 -->  <property name="mappingLocations">      <list>         <value>hbm/*.hbm.xml</value>      </list>   </property>

<!-- 添加额外属性 --> <property name="hibernateProperties">     <props>  <prop key="hibernate.dialect">${hibernate.dialect}</prop>   <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>   <prop key="hibernate.format_sql">${hibernate.format_sql}</prop>    <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>     </props>  </property></bean>

8.使用aop，配置事务管理器

   1)导入命名空间

<beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:aop="http://www.springframework.org/schema/aop"    xmlns:tx="http://www.springframework.org/schema/tx"    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/aop/spring-aop.xsd         http://www.springframework.org/schema/tx        http://www.springframework.org/schema/tx/spring-tx.xsd">

 

   2)找到事务管理的属性：

      spring-orm--->org.springframework.orm--->hibernate4---->HibernateTracsactionManager

<!-- 配置事务管理器 --><bean id ="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">   <!-- 注入sessionFactory对象 -->     <property name="sessionFactory" ref="mySessionFactory"/></bean>  <!-- 配置声明性事务，用aop对方法增强 -->      <!-- 分发需要增强的方法的通知 --> <tx:advice id = "txAdvice" transaction-manager="transactionManager">   <tx:attributes>      <tx:method name="add*" propagation="REQUIRED"/>      <tx:method name="delete*" propagation="REQUIRED"/>      <tx:method name="update*" propagation="REQUIRED"/>      <tx:method name="query*" propagation="REQUIRED"/>      <tx:method name="*" propagation="REQUIRED" rollback-for="java.lang.Exception"/>     </tx:attributes>  </tx:advice>  <!-- 组装通知和切点 --> <aop:config>   <!-- 配置切入点第一个*:代表的是拦截的方法的返回值类型 一般拦截的都是service包下的 service后面的一个点表示只能访问一级包，两个点表示可以访问service下面的所有子包  第二个*:表示service下面所有子包的所有类  第三个*:表示service下面所有子包的所有类的所有方法(..)表示service下面所有子包的所有类的所有方法的参数，第一个点是参数类型，第二个是参数个数                 -->     <aop:pointcut expression="execution(* com.xkf.ssh.service..*.*)" id="cut"/>     <!-- 组装通知 -->     <aop:advisor advice-ref="txAdvice" pointcut-ref="cut"/>  </aop:config>

到此，整个框架搭建完成。

  在resource文件夹下面建立context文件夹：applicationContext-framework.xml，将之前所有的框架配置文件全部移动到这里，为了维护的方便，让applicationContext.xml里面只是引入框架文件即可。

<span style="font-size:14px;"><!-- 引入框架配置文件 -->   <import resource="context/applicationContext-framework.xml"/></span>

在context文件夹下建applicationContext-student.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"    xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd">                        <!-- 配置dao层 -->        <bean id = "stuDao" class="com.xkf.ssh.dao.StudentDaoImpl">           <!-- 注入sessionFactory   ref引入spring容器里面配置好的sessionFactory-->           <property name="sessionFactory" ref = "mySessionFactory"></property>        </bean>        <!-- 配置service层 -->        <bean id="stuService" class="com.xkf.ssh.service.StudentServiceImpl">           <property name="stuDao" ref="stuDao"/>        </bean>                <!-- 配置action   注意：这里要记得加上scope属性为prototype，因为spring容器默认是单例模式，应该设置成多例模式，避免每次实现添加的时候都要重启服务器创建新的entity-->        <bean id = "stuAction" class="com.xkf.ssh.action.StudentAction" scope="prototype">          <!-- 注入service -->          <property name="stuService" ref="stuService"/>        </bean></beans>

在resource文件夹里面建立config文件夹：struts-student.xml

   

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN""http://struts.apache.org/dtds/struts-2.3.dtd"><struts>  <package name="student" extends="base" namespace="/student">    <action name="studentAction_*" class="stuAction" method="{1}">       <result>/index.jsp</result>    </action>    <action name="goToAdd">       <result>/WEB-INF/student/add.jsp</result>    </action>  </package></struts>

在resource里面建：struts.xml：

 将struts2创建action的权利交给spring容器管理：

        在struts2-core---->org.apacge.struts2--->default.properties里面找到常量：struts.objectFactory = spring

<span style="font-size:14px;"><?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN""http://struts.apache.org/dtds/struts-2.3.dtd"><struts> <!-- 常量配置 -->   <!-- 把struts2创建action的权利交给spring容器管理 -->   <constant name="struts.objectFactory" value="spring"/>   <!-- 修改请求后缀 -->   <constant name="struts.action.extension" value="do"/>    <!-- 开启开发者模式 -->   <constant name="struts.devMode" value="true"/>   <!-- 自动加载xml文件 -->   <constant name="struts.configuration.xml.reload" value="true"/>         <!--导入外部文件  -->   <include file="config/struts-student.xml"/>      <!-- 配置基本包 -->   <package name="base" extends="struts-default" abstract="true">        </package></struts></span>

   spring容器应该在服务器启动的时候交给网站来实例化：

 在web.xml文件里面配置：

        在spring-web---->org.springframework---->web---->context--->ContextLoaderListener

<span style="font-size: 18px;"> </span><span style="font-size:14px;"><!-- 配置服务器启动自动实例化Spring容器 -->  <!-- 配置web容器监听器 -->  <listener>     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener></span>

web.xml配置文件：

<span style="font-size:14px;"><!-- 配置struts2启动过滤器 -->  <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>*.do</url-pattern>  </filter-mapping>    <filter-mapping>     <filter-name>struts2</filter-name>     <url-pattern>*.jsp</url-pattern>  </filter-mapping></span>

完整的web.xml文件：    

<span style="font-size:14px;"><?xml version="1.0" encoding="UTF-8"?><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_3_0.xsd" id="WebApp_ID" version="3.0">  <display-name>ssh</display-name>  <!-- 配置struts2启动过滤器 -->  <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>*.do</url-pattern>  </filter-mapping>    <filter-mapping>     <filter-name>struts2</filter-name>     <url-pattern>*.jsp</url-pattern>  </filter-mapping>    <!-- 配置服务器启动自动实例化Spring容器 -->  <!-- 配置web容器监听器 -->  <listener>     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>     <!-- 配置容器的初始化参数 -->  <context-param>  <param-name>contextConfigLocation</param-name>  <param-value>classpath:applicationContext.xml</param-value>  </context-param>      <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app></span>
