二 SSH整合：Spring整合Hibernate，无障碍整合&无核心配置整合，Hibernate模版常用方法，

重建SSH项目

java项目可以直接复制，但是web项目除了改名字还要该配置，如下：

方式一：无障碍整合：带Hibernate配置文件

<?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"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.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">

     <!-- Spring整合Hibernate -->
     <!-- 引入Hibernate配置信息===== -->
     <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!-- 引入Hibernate配置文件 -->
        <property name="configLocation" value="classpath:hibernate.cfg.xml"/>
     </bean>

     <!-- 配置事务管理器 -->
     <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
       <property name="sessionFactory" ref="sessionFactory"/>
     </bean>

     <!-- 开启注解事务,在业务层使用注解@Transactional -->
     <tx:annotation-driven transaction-manager="transactionManager"/>

     <!--  通过context标签引入jdbc.properties，在Hibernate核心配置文件里，免去 -->

     <!-- 配置C3P0连接池，在Hibernate核心配置文件里面，免去 -->

    <!-- 配置Action -->
    <bean id="customerAction" class="com.ssh.web.action.CustomerAction" scope="prototype">
       <property name="customerService" ref="customerService"/>
    </bean>

    <!-- 注入CustomerService -->
    <bean id="customerService" class="com.ssh.service.impl.CustomerServiceImpl">
    <property name="customerDao" ref="customerDao"/>
    </bean>

    <!--
     注入Dao
    CustomerDaoImpl继承HibernateDaoSupport,在Dao注入SessionFactory,创建HibernateTemplate模版
    -->
    <bean id="customerDao" class="com.ssh.dao.impl.CustomerDaoImpl">
    <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

</beans>

方式二：不带Hibernate核心配置文件，将核心配置文件给Spring管理

Hibernate配置文件：

• 数据库连接的配置
• Hibernate属性的配置：方言，显示sql,格式化sql。。。。
• C3P0连接池
• 映射

将Hibernate的核心配置交给Spring：

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

    http://www.springframework.org/schema/tx/spring-tx.xsd">

     <!--通过context标签引入jdbc.properties -->
     <context:property-placeholder location="classpath:jdbc.properties"/>

     <!-- 配置C3P0连接池 -->
     <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
       <property name="driverClass" value="${jdbc.driverClass}"/>
       <property name="jdbcUrl" value="${jdbc.url}"/>
       <property name="user" value="${jdbc.user}"/>
       <property name="password" value="${jdbc.password}"/>
     </bean>

     <!-- Spring整合Hibernate -->
     <!-- 方式二：不带Hibernate核心文件配置===== -->
     <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
          <!-- 注入连接池 -->
          <property name="dataSource" ref="dataSource" />

          <!-- 配置Hibernate相关属性 -->
          <property name="hibernateProperties">

           <props>
           <!-- 配置方言,打印语句,格式化sql,自动建表 -->
              <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
              <prop key="hibernate.show_sql">true</prop>

              <prop key="hibernate.hbm2ddl.auto">update</prop>
           </props>
          </property>

          <!-- 设置映射 -->
          <property name="mappingResources">
          <list>
             <value>com/ssh/domain/Customer.hbm.xml</value>
          </list>

          </property>

     </bean>

     <!-- 配置事务管理器 -->
     <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
       <property name="sessionFactory" ref="sessionFactory"/>
     </bean>

     <!-- 开启注解事务,在业务层使用注解@Transactional -->
     <tx:annotation-driven transaction-manager="transactionManager"/>

    <!-- 配置Action -->
    <bean id="customerAction" class="com.ssh.web.action.CustomerAction" scope="prototype">
       <property name="customerService" ref="customerService"/>
    </bean>

    <!-- 注入CustomerService -->
    <bean id="customerService" class="com.ssh.service.impl.CustomerServiceImpl">
    <property name="customerDao" ref="customerDao"/>
    </bean>

    <!--

    -->
    <bean id="customerDao" class="com.ssh.dao.impl.CustomerDaoImpl">
    <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

</beans>

Hibernate模版常用方法：

• 增
• 删
• 改
• 查 一个： get(Class c , Serializable id)   load(Class c , Serializable id)
• 查多个：list find(String hql,Object...args)   list findByCriteria(DetachedCriteria dc)
• 分页：list findByCriteria(DetachedCriteria dc,int firstResult,int maxResult)
• 命名查询(了解)
