当spring 容器初始化完成后执行某个方法

package com.yk.test.executor.processor;

import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;

public class InstantiationTracingBeanPostProcessor implements ApplicationListener<ContextRefreshedEvent> {

public void onApplicationEvent(ContextRefreshedEvent event) {
if (event.getApplicationContext().getParent() == null) {// root
System.out.println("=====================================");
System.out.println("============spring 初始化完成===========");
System.out.println("============spring 初始化完成===========");
System.out.println("=====================================");
}
}

}
