Struts+Spring+Hibernate连接数据库的三个方法

第一种在Spring applicationContext.xml中连接：

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">

<property name="driverClassName">

<value>oracle.jdbc.driver.OracleDriver</value>

</property>

<property name="url">

<value>jdbc:oracle:thin:@localhost:1521:test</value>

</property>

<property name="username">

<value>cpiclh</value>

</property>

<property name="password">

<value>cpiclh</value>

</property>

</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="dataSource">

<ref local="dataSource" />

</property>

<property name="mappingResources">

<list>

<value>com/Hibernate/Pojo/FactUsers.hbm.xml</value>

</list>

</property>

<property name="hibernateProperties">

<props>

<prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>

<prop key="hibernate.show_sql">true</prop>

</props>

</property>

</bean>

第二种在Hibernate hibernate.cfg.xml中连接：

<session-factory>

<property name="connection.username">root</property>

<property name="connection.url">

jdbc:oracle:thin:@192.168.0.1:1521:test

</property>

<property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>

<property name="connection.password">root</property>

<property name="connection.driver_class">

oracle.jdbc.driver.OracleDriver

</property>

<mapping resource="com/hibernate/pojo/FactUsers.hbm.xml" />

</session-factory>

第三种在Tomcat中的 apache-tomcat-5.5.17\conf\Catalina目录下放一个

和目录同名的XML，内容如下

<Context path="" docBase="ROOT">

<Resource name="jdbc/db" auth="Container" type="javax.sql.DataSource" removeAbandoned="true" removeAbandonedTimeout="60"

username="root" password="root" driverClassName="oracle.jdbc.driver.OracleDriver"

url="jdbc:oracle:thin:@192.168.0.1:1521:test"/>

</Context>
