寫一個類繼承ApplicationListener，可以直接引用下述程式碼，然後呼叫相應的方法。

package com.linewell.system;

import com.linewell.cache.ApplicationData;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
import org.springframework.stereotype.Component;

@Component
 
public class InitializationProcessor implements ApplicationListener<ContextRefreshedEvent> {


    @Override
    public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
        if (contextRefreshedEvent.getApplicationContext().getParent() == null) {
            System.out.println(
 
"run onApplicationEvent method");

            //dosomething
        }
    }
}
