当我在bean中配置了<property name="dao" ref="steerdao"></property>后为什么只调用了初始化方法，并没有调用destroy()方法？

配置文件如下:

<bean name="chineseSteer" class="com.ly.spring.action.Chinese">

<property name="serivce" ref="steerService"></property>

</bean>

public class Chinese implements InitializingBean,DisposableBean{

public void show() {

serivce.chop();

}

@Override

public void destroy() throws Exception {

System.out.println("destroy()");

}

@Override

public void afterPropertiesSet() throws Exception {

System.out.println("afterPropertiesSet()");

}
