Question

我的项目是Spring-boot（1.3.5 RELEASE），Web Project（Spring-Web 4.3.0 REALESE）。我想在加载spring之后使用＆＃34; ApplicationListener＆＃34;来做某事。但是我的代码不起作用。我的代码是：

package hello;

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

public class BootListener implements ApplicationListener<ContextRefreshedEvent>{

@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
    System.out.println("Spring启动监听器");
    System.out.println(event.getTimestamp());
  }
}

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {

  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }
}

Answer 1

你需要让你的事件监听器成为单身人士，所以Spring可以选择这个。使用BootListener注释@Component。

要自己发布活动，请注入ApplicationEventPublisher。

无法使用Spring ApplicationListener
