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 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;
}
}

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
