SSH中的H最主要解决的是ORM，实体和数据库里面数据的映射，连接数据库我们是写在spring里面实现的，通过依赖注入把H注入到S中，代码如下：
<!– dataSource injection–> <bean id=”DataSource” class=”org.springframework.jdbc.datasource.DriverManagerDataSource” > <property name=”driverClassName” value=”com.mysql.jdbc.Driver”/> <property name=”url” value=”jdbc:mysql://localhost:3306/tna”/> <property name=”username” value=”root”/> <property name=”password” value=”root”/> </bean> <!– sessionFactory injection–> <bean id=”SessionFactory” class=”org.springframework.orm.hibernate3.LocalSessionFactoryBean”> <property name=”dataSource” ref=”DataSource”/> <property name=”hibernateProperties”> <props> <prop key=”hibernate.dialect”>org.hibernate.dialect.DerbyDialect</prop> <prop key=”hibernate.show_sql”>true</prop> <prop key=”hibernate.format_sql”>true</prop> </props> </property> <property name=”mappingResources”> <list> <value>com/oracle/tna/domain/User.hbm.xml</value> <value>com/oracle/tna/domain/Item.hbm.xml</value> <value>com/oracle/tna/domain/Score.hbm.xml</value> <value>com/oracle/tna/domain/Admin.hbm.xml</value> <value>com/oracle/tna/domain/Userscore.hbm.xml</value> </list> </property> </bean> <!– hibernateTemplate injection–> |
