Spring—Hibernate

1.家jar包

2配置applicationContext与xxx.hbm.xml(根据需要决定是否配置hibernate.hbm.xml）

applicationContext.xml

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

<!-- 一、配置数据库连接池 ComboPooledDataSource -->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">

<!-- Connection properties -->
<property name="driverClass" value="${driverClass}" />
<property name="jdbcUrl" value="${jdbcUrl}" />
<property name="user" value="${username}" />
<property name="password" value="${password}" />
<!-- Pool properties-->
<property name="minPoolSize" value="2" />
<property name="maxPoolSize" value="10" />
<property name="maxStatements" value="50" />
<property name="idleConnectionTestPeriod" value="3000" />
<property name="loginTimeout" value="300" />

</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>

<!--方式一
直接从外部读取配置文件，此时需要有相应的Hibernate。hbm.xml，xxx.hbm.xml配置，容器找不到的配置会在这个路径去找 -->
<property name="configLocation" value="classpath:hibernate.cfg.xml"></property>

<!-- 方式二：
若没有外部Hibernate.hbm.xml配置文件，只能在自身文件查找，但相应的xxx.hbm.xml(bean对应的文件)还需添加。
注意：再配置hibernate其他属性的时候在名字前要加上hibernate，否则配置无效
<property name="mappingResources">
<list>
引入xxx.hbm.xml
<value>com/donghua/jdbc_dao/User.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props >
配置hibernate的其他配置
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
