java web启动后执行初始化任务

写一个类继承ApplicationListener，可以直接引用下述代码，然后调用相应的方法。

1package com.linewell.system;
2
3import com.linewell.cache.ApplicationData;
4import org.springframework.context.ApplicationListener;
5import org.springframework.context.event.ContextRefreshedEvent;
6import org.springframework.stereotype.Component;
7
8@Component
9public class InitializationProcessor implements ApplicationListener<ContextRefreshedEvent> {
10
11
12    @Override
13    public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
14        if (contextRefreshedEvent.getApplicationContext().getParent() == null) {
15            System.out.println("run onApplicationEvent method");
16            //dosomething
17        }
18    }
19}
