在spring boot webapp就绪后自动启动浏览器

Question

如何在启动Spring启动应用程序后自动启动浏览器。是否有任何侦听器方法回调来检查webapp是否已经部署并准备好提供请求，以便在浏览器加载时，用户可以看到索引页并开始与webapp交互？

public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
    // launch browser on localhost 
}

Answer 1

您可以通过一些java代码来实现。我不确定Spring靴是否有现成的东西。

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

public class Browser {
    public static void main(String[] args) {
        String url = "http://www.google.com";

        if(Desktop.isDesktopSupported()){
            Desktop desktop = Desktop.getDesktop();
            try {
                desktop.browse(new URI(url));
            } catch (IOException | URISyntaxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }else{
            Runtime runtime = Runtime.getRuntime();
            try {
                runtime.exec("xdg-open " + url);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}

@SpringBootApplication
@ComponentScan(basePackageClasses = com.io.controller.HelloController.class)
public class HectorApplication {

    public static void main(String[] args) throws IOException {
       SpringApplication.run(HectorApplication.class, args);
       openHomePage();
    }

    private static void openHomePage() throws IOException {
       Runtime rt = Runtime.getRuntime();
       rt.exec("rundll32 url.dll,FileProtocolHandler " + "http://localhost:8080");
    }
}

下面的代码为我工作：

@EventListener({ApplicationReadyEvent.class})
void applicationReadyEvent() {
    System.out.println("Application started ... launching browser now");
    browse("www.google.com");
}

public static void browse(String url) {
    if(Desktop.isDesktopSupported()){
        Desktop desktop = Desktop.getDesktop();
        try {
            desktop.browse(new URI(url));
        } catch (IOException | URISyntaxException e) {
            e.printStackTrace();
        }
    }else{
        Runtime runtime = Runtime.getRuntime();
        try {
            runtime.exec("rundll32 url.dll,FileProtocolHandler " + url);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
