1、MainConfigOfLifeCycle

/**
     * 2）、通过让Bean实现InitializingBean（定义初始化逻辑）；
     * 				                实现DisposableBean（定义销毁逻辑）;
     */
    @ComponentScan("com.atguigu.bean")
    @Configuration
    public class MainConfigOfLifeCycle {
    
    }

2、创建类Cat 。实现InitializingBean和DisposableBean 接口

@Component
    public class Cat implements InitializingBean,DisposableBean {
    	
    	public Cat(){
    		System.out.println("cat constructor...");
    	}
    
    	@Override
    	public void destroy() throws Exception {
    		// TODO Auto-generated method stub
    		System.out.println("cat...destroy...");
    	}
    
    	@Override
    	public void afterPropertiesSet() throws Exception {
    		// TODO Auto-generated method stub
    		System.out.println("cat...afterPropertiesSet...");
    	}
    
    }

3、测试

@Test
    public void test01(){
    	//1、创建ioc容器
    	AnnotationConfigApplicationContext applicationContext = new AnnotationConfigApplicationContext(MainConfigOfLifeCycle.class);
    	System.out.println("容器创建完成...");
    	
    	//关闭容器
    	applicationContext.close();
    }
