@Controller
public class    @RequestMapping("/")
    public String toIndex() {// 配置默认访问首页
        return "redirect:/index.jsp";

　　//自动打开浏览器
    @EventListener({ApplicationReadyEvent.class})
    void applicationReadyEvent() {
        String url = "http://localhost:9999/index.jsp";
        Runtime runtime = Runtime.getRuntime();
        try {
            runtime.exec("rundll32 url.dll,FileProtocolHandler " + url);

//创建一个独立的文件  配置全局启动
