Spring回调方法DisposableBean接口 博客分类： spring  

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

 

 

 

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：

 

 

 

<? 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：

 

 

 

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
