Spring注解系列十二：生命周期-InitializingBe

转:https://blog.csdn.net/lizhiqiang1217/article/details/89950199

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();
}
