除了自定义的destroy-method.还可以实现DisposableBean接口,来回调bean销毁时候执行的方法,这个接口有一个destroy方法,生命周期是是destroy----bean销毁---自定义的destroy方法

package ch5.destroy; import java.io.File; import org.springframework.beans.factory.BeanFactory; import org.springframework.beans.factory.config.ConfigurableListableBeanFactory; import org.springframework.beans.factory.support.BeanDefinitionRegistry; import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.core.io.FileSystemResource; public class TestSpring{ public static void main(String args[]) throws Exception{ //获取bean factory ConfigurableListableBeanFactory factory=(ConfigurableListableBeanFactory)getBeanFactory(); //使用子beanFactory SimpleBean bean1=(SimpleBean)factory.getBean( "SimpleBean" ); System.out.println( "before destroy" ); factory.destroySingletons(); System.out.println( "after destory" ); } public static BeanFactory getBeanFactory(){ //获取bean factory String realpath= "" ; //加载配置项 realpath=System.getProperty( "user.dir" )+File.separator+ "src" +File.separator+ "ch5/destroy" +File.separator+ "applicationContext.xml" ; ConfigurableListableBeanFactory factory= new XmlBeanFactory( new FileSystemResource(realpath)); return factory; } } |
结果:
this is info from afterpropertiesSet from SimpleBean
before destroy
this is info from destroy method
this is info from customer destroy method
after destory
