Answer 1

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://localhost/testeclipse"></property>
<property name="username" value="root"></property>
<property name="password" value="root"></property>
</bean>
代码如上
