### 1、手动给spring加入监听任务 ###

#### 1、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 ####

@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() {
            try {
                Runtime.getRuntime().exec("cmd   /c   start   http://localhost:8080/index");
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }

#### 2、写1个监听器，监听项目加载完后执行指定操作 ####

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();
        }
    }

#### 3、给springboot的启动类添加监听任务 ####

@SpringBootApplication
    public class SpeechApplication {
     
        public static void main(String[] args) {
            SpringApplication springApplication = new SpringApplication(SpeechApplication .class);
            springApplication.addListeners(new ApplicationStartup());
            springApplication.run(args);
        }
    }

### 2、spring容器加载完自动监听 ###

#### 1、实现springboot默认的监听接口，该方法在spring容器加载完自动监听 ####

import org.springframework.beans.factory.annotation.Value;
    import org.springframework.boot.CommandLineRunner;
    import org.springframework.stereotype.Component;
    
    
    /**
     * 配置自动启动浏览器
     */
    
    @Component
    public class MyCommandRunner implements CommandLineRunner {
    
        @Value("${server.port}")
        private String port;
    
        @Override
        public void run(String... args) {
            try {
                Runtime.getRuntime().exec("cmd   /c   start   http://localhost:" + port + "/index");
            } catch (Exception ex) {
                ex.printStackTrace();
            }
        }
    }

#### 2、正常启动 ####

@EnableWebMvc
    @SpringBootApplication
    public class PhotoShowApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(PhotoShowApplication.class, args);
        }
    }
