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
