<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
    <property name="url" value="${url}"/>
    <property name="username" value="root"/>
    <property name="password" value="123"/>
</bean>

value里面直接写参数

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
    <property name="url" value="jdbc:mysql://localhost:3306/y2"/>
    <property name="username" value="root"/>
    <property name="password" value="123"/>
