Java内置HttpServer的使用

一、相关类

1.HttpServer

表示一个服务器实例，需要绑定一个IP地址和端口号

2.HttpContext

服务器监听器的上下文

3.HttpHandler

上下文对应的http请求处理器

4.HttpExchange

监听器回调时传入的参数，封装了http请求和响应的所有数据操作

二、使用

public class MyServer {

    public static void main(String[] args) throws IOException {
        HttpServer httpServer = HttpServer.create(new InetSocketAddress(9090), 0);
        httpServer.createContext("/hello", new MyHandler());
        httpServer.start();
        System.out.println("server start...");
    }

    static class MyHandler implements HttpHandler {

        @Override
        public void handle(HttpExchange exchange) throws IOException {
            String response = "Hello World";
            exchange.sendResponseHeaders(200, 0);
            OutputStream os = exchange.getResponseBody();
            os.write(response.getBytes("UTF-8"));
            os.close();
        }
    }
}
