本篇文章拿springboot启动后,自动打开1个浏览器访问项目的html5页面来演示
介绍2种方法,推荐第2种
第一种 手动给spring加入监听任务,比较麻烦
第1步:先写1个线程类,在springboot启动加载完,自动执行的操作放在里面
package com.sinosoft.speech.util;
import org.springframework.stereotype.Component;
/**
* 需要执行的操作
* @author lijunming
* @date 2018/7/22 下午2:54
*/
@Component
public class StepExecutor implements Runnable {
@Override
public void run() {
startStreamTask();
}
/**
* 项目启动后打开1个页面
*/
public void startStreamTask() {
System.out.println("开始启动1个页面");
try {
Runtime.getRuntime().exec("cmd /c start http://localhost:8080/index");
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
第2步,写1个监听器,监听项目加载完后执行指定操作
package com.sinosoft.speech.util;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationListener;
import org.springframework.context.event.ContextRefreshedEvent;
/**
* spring boot 容器加载完成后执行
* @author lijunming
* @date 2018/7/22 下午3:04
*/
public class ApplicationStartup implements ApplicationListener<ContextRefreshedEvent> {
@Override
public void onApplicationEvent(ContextRefreshedEvent event) {
ApplicationContext ac = event.getApplicationContext();
StepExecutor StepExecutor = ac.getBean(StepExecutor .class);
Thread thread = new Thread(StepExecutor);
thread.start();
}
}
第3步,给springboot的启动类添加监听任务
package com.sinosoft.speech;
import com.sinosoft.speech.util.ApplicationStartup;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @author lijunming
* @date 2018/7/22 下午2:40
*/
@SpringBootApplication
public class SpeechApplication {
public static void main(String[] args) {
SpringApplication springApplication = new SpringApplication(SpeechApplication .class);
springApplication.addListeners(new ApplicationStartup());
springApplication.run(args);
}
}
第二种 spring容器加载完自动监听
第1步,实现springboot默认的监听接口,该方法在spring容器加载完自动监听
package com.sinosoft.speech.util;
import com.sinosoft.speech.swing.Main;
import org.springframework.boot.CommandLineRunner;
import org.springframework.stereotype.Component;
/**
* spring boot 容器加载后自动监听
* @author lijunming
* @date 2018/7/22 下午2:30
*/
@Component
public class MyCommandRunner implements CommandLineRunner {
@Override
public void run(String... args) {
System.out.println("开始启动1个页面");
try {
Runtime.getRuntime().exec("cmd /c start http://localhost:8080/index");
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
2.正常启动就行
package com.sinosoft.speech;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* @author lijunming
* @date 2018/7/22 下午2:40
*/
@SpringBootApplication
public class SpeechApplication {
public static void main(String[] args) {
SpringApplication.run(SpeechApplication.class, args);
}
}
配置完后,运行springboot启动类,就会自动打开1个浏览器访问项目的html5页面,效果如下
