Struts2+Spring2.5+Hibernate3.3整合开发附源代码
第一步在
Spring
中配置数据源：
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> <property name="driverClass" value="org.gjt.mm.mysql.Driver"/> <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssh2?useUnicode=true&characterEncoding=UTF-8"/> <property name="user" value="root"/> <property name="password" value="hjc"/> <!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 --> <property name="initialPoolSize" value="1"/> <!--连接池中保留的最小连接数。--> <property name="minPoolSize" value="1"/> <!--连接池中保留的最大连接数。Default: 15 --> <property name="maxPoolSize" value="300"/> <!--最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 --> <property name="maxIdleTime" value="60"/> <!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 --> <property name="acquireIncrement" value="5"/> <!--每60秒检查所有连接池中的空闲连接。Default: 0 --> <property name="idleConnectionTestPeriod" value="60"/> </bean>第二步集成进 hibernate ：
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="mappingResources"> <list> <value>org/ssh2/bean/Employee.hbm.xml</value> </list> </property> <property name="hibernateProperties"> <value> hibernate.dialect=org.hibernate.dialect.MySQL5Dialect hibernate.hbm2ddl.auto=update hibernate.show_sql=false hibernate.format_sql=false </value> </property> </bean>第三步使用 Spring 容器管理事务服务：
<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"> <property name="sessionFactory" ref="sessionFactory"/> </bean> <!--使用基于注解方式配置事务 --> <tx:annotation-driven transaction-manager="txManager"/>
