sub/pub模式在软件设计中是非常常见的，他可以很优雅的帮我们解耦合，很多优秀的软件中都能看到他的影子，不如redis,zk,rxjava等，spring的内部也有很多的应用，今天我们就说一下事件的监听。
首先我们要知道事件的种类是多种多样的，我们的事件监听器（EventListener）关注什么样的事件呢？根据这个思路我们看下本次课程我们定义的
package com.shuqi.listener;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
import java.util.stream.Stream;
@Slf4j
public class TestListener implements ApplicationListener<ContextRefreshedEvent> {
@Override
public void onApplicationEvent(ContextRefreshedEvent contextRefreshedEvent) {
ApplicationContext applicationContext = contextRefreshedEvent.getApplicationContext();
Stream.of(applicationContext.getBeanNamesForType(Object.class)).forEach(log::info);
}
}
实例中的事件监听器关注的是ContextRefreshedEvent的事件，也就是说当容器refresh结束的时候会发出这个事件，我们的监听器就能监听到，所做的操作就是打印容器中的Bean的名称。
那么我们事件是有了，我们下一步就不要将这个事件监听器让Spring boot知道，所以就是一个注册。
package com.shuqi;
import com.shuqi.listener.TestListener;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import java.text.SimpleDateFormat;
import java.util.Date;
@SpringBootApplication
public class ApplicationMain {
public static void main(String[] args) {
SpringApplication springApplication=new SpringApplication(ApplicationMain.class);
springApplication.addListeners(new TestListener());
springApplication.run(args);
System.out.println(new SimpleDateFormat("[yyyy-MM-dd HH:mm:ss]").format(new Date()) + " server started!");
}
}
这样我们一个事件监听器就完成了。
启动看看效果
