重建一個SSH專案

java專案可以直接複製，但是web專案除了改名字還要該配置，如下：

Hibernate配置檔案中有哪些內容：

• 資料庫連線的配置
• Hibernate屬性的配置：方言，顯示sql,格式化sql。。。。
• C3P0連線池
• 對映

將Hibernate的核心配置交給Spring：

<!-- 引入外部屬性檔案 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>
    <!-- 配置C3P0連線池 -->
 

     <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 -->
    <!-- 引入Hibernate的配置資訊 -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
     <!-- 方式二：Hibernate核心配置已去掉 -->
     <!-- 注入連線池 -->
     <
 
property name="dataSource" ref="dataSource"/>
     <!-- 配置Hibernate的相關屬性 -->
     <property name="hibernateProperties">
     <props>
        <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
        <prop key="hibernate.show_sql">true</prop>
        <prop key="hibernate.format_sql">true</prop>
        <prop key="hibernate.hbm2ddl.auto">update</prop>
     </props>
     </property>
     
     <!-- 設定對映檔案 -->
     <property name="mappingResources">
     <list>
       <value>com/itheima/ssh/domain/Customer.hbm.xml</value>
     </list>
     </property>
    </bean>

 測試：

Hibernate模版常用方法：

• 增
• 刪
• 改
• 查 一個： get(Class c , Serializable id)   load(Class c , Serializable id)
• 查多個：list find(String hql,Object...args)   list findByCriteria(DetachedCriteria dc)   分頁：list findByCriteria(DetachedCriteria dc,int firstResult,int maxResult)  命名查詢(瞭解)
