Spring容器关闭前执行销毁方法的几种方式

1、DisposableBean

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.DisposableBean;
import org.springframework.stereotype.Component;

@Slf4j
@Component
public class DisposableBeanDemo implements DisposableBean {
    @Override
    public void destroy() throws Exception {
        log.info("invoke destroy");
    }
}

 

2、SmartLifecycle

import lombok.extern.slf4j.Slf4j;
import org.springframework.context.SmartLifecycle;
import org.springframework.stereotype.Component;

@Slf4j
@Component
public class SmartLifecycleDemo implements SmartLifecycle {
    private boolean running;

    @Override
    public void start() {
        log.info("start >>>>");
        running = true;
    }

    @Override
    public void stop() {
        log.info("stop >>>>");
    }

    @Override
    public boolean isRunning() {
        return running;
    }
    
    @Override
    public int getPhase() {
        return Integer.MAX_VALUE;
    }
}

 

3、使用InitializingBean设置钩子函数addShutdownHook

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.InitializingBean;

@Slf4j
public class InitializingBeanDemo implements InitializingBean {
    @Override
    public void afterPropertiesSet() throws Exception {
        Runtime.getRuntime().addShutdownHook(new Thread(() -> {
            System.out.println("addShutdownHook>>>>>");

        }));
    }
}

 

4、@PreDestroy注解

    @PreDestroy
    public void preDestroy(){
        log.info("PreDestroy>>>>");
    }
