有时候bean之间的依赖不是那么直接,例如,数据库的驱动注册,在类的静态初始化中执行,`depends-on`属性指定的bean,要求在此bean之前实例化.如下
~~~xml
<bean id="beanOne" class="ExampleBean" depends-on="manager"/>
<bean id="manager" class="ManagerBean" />
~~~
如果依赖多个bean,可以使用逗号,分号,空格分割开
~~~xml
<bean id="beanOne" class="ExampleBean" depends-on="manager,accountDao">
<property name="manager" ref="manager" />
</bean>
<bean id="manager" class="ManagerBean" />
<bean id="accountDao" class="x.y.jdbc.JdbcAccountDao" />
~~~
>`depends-on`依赖的bean在此bean本身销毁之前先销毁
