我想從Spring-database.xml引用一個bean（dataSource）到spring-security.xml，我得到錯誤「沒有名爲'dataSource'的bean被定義」。如何從數據源xml導入引用bean？
彈簧database.xml
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<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/world" />
<property name="username" value="root" />
<property name="password" value="root" />
</bean>
</beans>
彈簧的security.xml
