spring容器bean生命周期验证简单实例

接rocketMQ的consumerMessageHook时遇到了一个生命周期位置的问题

这里写了一个小demo验证下生命周期

打印顺序

1. LifeCycleTest 实例化

2. LifeCycleTest setName：lifeCycleTest

3. LifeCycleTest setApplicationContext

4. LifeCycleTest afterPropertiesSet

5. LifeCycleTest afterSingletonsInstantiated

6. LifeCycleTest isRunning

7. LifeCycleTest start

停止服务时

1. LifeCycleTest isRunning

2. LifeCycleTest stop

3. LifeCycleTest destroy

@Component
public class LifeCycleTest implements SmartInitializingSingleton, SmartLifecycle, InitializingBean, DisposableBean,
        BeanNameAware, ApplicationContextAware {
    boolean isRunning = false;
    public LifeCycleTest() {
        System.out.println("LifeCycleTest 实例化");
    }
    @Override
    public void setBeanName(String s) {
        System.out.println("LifeCycleTest setName：" + s);
    }
    @Override
    public void destroy() throws Exception {
        System.out.println("LifeCycleTest destroy");
    }
    @Override
    public void afterPropertiesSet() throws Exception {
        System.out.println("LifeCycleTest afterPropertiesSet");
    }
    @Override
    public void afterSingletonsInstantiated() {
        System.out.println("LifeCycleTest afterSingletonsInstantiated");
    }
    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        System.out.println("LifeCycleTest setApplicationContext");
    }
    @Override
    public void start() {
        isRunning = true;
        System.out.println("LifeCycleTest start");
    }
    @Override
    public void stop() {
        System.out.println("LifeCycleTest stop");
    }
    @Override
    public boolean isRunning() {
        System.out.println("LifeCycleTest isRunning");
        return isRunning;
    }
}
