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 

 

SimpleBean.java

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35

package  ch5.destroy; import  org.springframework.beans.factory.DisposableBean; import  org.springframework.beans.factory.InitializingBean; public  class  SimpleBean  implements  InitializingBean,DisposableBean {    public  void  afterPropertiesSet()  throws  Exception {          System.out.println( "this is info from afterpropertiesSet from SimpleBean" );      } private   String name;    private  String sex;    private  String age;    public  void  destroyMethod(){        System.out.println( "this is info from customer destroy method" );    }    public  void  destroy(){        System.out.println( "this is info from destroy method" );    } public  String getAge() {      return  age; } public  void  setAge(String age) {      this .age = age; } public  String getName() {      return  name; } public  void  setName(String name) {      this .name = name; } public  String getSex() {      return  sex; } public  void  setSex(String sex) {      this .sex = sex; } }

配置文件：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<? xml  version = "1.0"  encoding = "UTF-8" ?> < 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-2.0.xsd" > < bean  id = "SimpleBean"  class = "ch5.destroy.SimpleBean"  destroy-method = "destroyMethod" > < property  name = "name" >      < value >gaoxiang</ value >    </ property > < property  name = "sex" >     < value >male</ value > </ property > < property  name = "age" >      < value >26</ value >    </ property > </ bean > </ beans >

测试代码：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

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
