SmartLifecycle 使用介绍
参考 https://blog.csdn.net/feiying0canglang/article/details/127156520
import org.springframework.context.SmartLifecycle;
import org.springframework.stereotype.Component;
@Component
public class MySmartLifecycle implements SmartLifecycle {
private volatile boolean running = false;
@Override
public boolean isAutoStartup() {
// 返回true 才能自动执行 start() 方法
return true;
}
@Override
public void stop(Runnable callback) {
// 结束应用后会调用
System.out.println("stop(callback)");
// stop();
callback.run();
}
@Override
public void start() {
System.out.println("start()");
running = true;
}
@Override
public void stop() {
System.out.println("stop()");
running = false;
}
@Override
public boolean isRunning() {
System.out.println("isRunning " + running);
return running;
}
@Override
public int getPhase() {
// 数字越小,执行顺序越靠前
return 0;
}
}
说明:
- stop(Runnable callback) ,结束应用后,会自己执行。
- stop() 不会自己执行,要手动调用。
- isAutoStartup() 返回 true,才能执行 start() 。
import org.springframework.context.annotation.Bean;

import org.springframework.context.support.DefaultLifecycleProcessor;
@Configuration
public class MySmartLifecycleConfig {
// 执行异步 stop(Runnable runnable)关闭的 超时 方法
@Bean
public DefaultLifecycleProcessor defaultLifecycleProcessor(){
// 默认是30秒 private volatile long timeoutPerShutdownPhase = 30000L;
DefaultLifecycleProcessor defaultLifecycleProcessor = new DefaultLifecycleProcessor();
defaultLifecycleProcessor.setTimeoutPerShutdownPhase( 30000L);
return defaultLifecycleProcessor;
}
