404 Not Found 找不到请求的上下文

Question

如下图所示，我的 HTML 索引页面位于静态文件夹中。如何将 localhost 指向 static/index.html

我自己在基本的 hello world 上尝试过。

static class MyHandler implements HttpHandler { 
    public void 
    handle(HttpExchange t) throws IOException { 
    String response = "Hello world"; 
        t.sendResponseHeaders(200, response.length()); 
        OutputStream os = t.getResponseBody();
        os.write(response.getBytes()); os.close(); 
} 
}

我需要知道如何将默认 localhost:8080 指向我预先构建的现有 static/index.html 页面？

如果我在您的应用程序启动时正确理解了您的问题，您希望将您的页面显示为默认页面 请通过以下链接

这会让你知道如何配置你的 web.xml 页面，让 tomcat 或任何其他 web 容器知道你的默认页面。

你可以试试这个

public class Test {

    public static void main(String[] args) throws Exception {
        HttpServer server = HttpServer.create(new InetSocketAddress(8000), 0);
        server.createContext("/welcomePage", new MyHandler());
        server.setExecutor(null); // creates a default executor
        server.start();
    }

    static class MyHandler implements HttpHandler {
        @Override
        public void handle(HttpExchange t) throws IOException {
            String response = "This is the response";
            // we do not set content type, headers, cookies etc.
        // resp.setContentType("text/html"); // while redirecting as
        // it would most likely result in an IllegalStateException

        // "/" is relative to the context root (your web-app name)
        RequestDispatcher view = req.getRequestDispatcher("/path/to/file.html");
        // don't add your web-app name to the path

        view.forward(req, resp);
        }
    }
}
