@Override
    public void afterPropertiesSet() {
        System.out.println("属性设置完后执行该方法");
    }

    @Override
    public void destroy() {
        System.out.println("结束前执行一些清理工作");
    }
}

在Spring bean配置文件中定义该bean:（配置文件名称为SpringConfig.xml)

[html] view plaincopyprint?
01.<?xml version="1.0" encoding="UTF-8"?> 
02. 
03.<beans xmlns="http://www.springframework.org/schema/beans" 
04.    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
05.    xsi:schemaLocation="http://www.springframework.org/schema/beans 
06.    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> 
07. 
08.   <bean id="simple" class="SimpleBean"> 
09.       <property name="name" value="I'm a Simple Bean"> 
10.   </bean> 
11.</beans> 
<?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-3.0.xsd">

   <bean id="simple" class="SimpleBean">
       <property name="name" value="I'm a Simple Bean">
   </bean>
</beans>
运行它：

[java] view plaincopyprint?
01.public class App  
02.{ 
03.    public static void main( String[] args ) 
04.    { 
05.        ConfigurableApplicationContext context =  
06.            new ClassPathXmlApplicationContext(new String[] {"SpringConfig.xml"}); 
07.  
08.        SimpleBean simple = (SimpleBean )context.getBean("simple"); 
09.  
10.        System.out.println(simple.getName()); 
11.
