我强烈建议考虑Simple，特别是如果您不需要Servlet功能，而只是访问请求/响应对象。如果你需要REST，你可以把Jersey放在上面，如果你需要输出HTML或类似的东西，有Freemarker。我真的很喜欢使用这个组合可以做的事情，而且需要学习的API相对较少。

Apache Commons HttpCore项目怎么样?

来自网站:…… HttpCore目标

实现最基本的HTTP传输方面 良好的表现和清晰的表达之间的平衡 API 小(可预测的)内存占用 自包含库(没有JRE以外的外部依赖)

试试这个https://github.com/devashish234073/Java-Socket-Http-Server/blob/master/README.md

这个API使用套接字创建了一个HTTP服务器。

它以文本的形式从浏览器获取请求 解析它来检索URL信息、方法、属性等。 使用定义的URL映射创建动态响应 将响应发送到浏览器。

例如，下面是response .java类中的构造函数如何将原始响应转换为http响应:

public Response(String resp){
    Date date = new Date();
    String start = "HTTP/1.1 200 OK\r\n";
    String header = "Date: "+date.toString()+"\r\n";
    header+= "Content-Type: text/html\r\n";
    header+= "Content-length: "+resp.length()+"\r\n";
    header+="\r\n";
    this.resp=start+header+resp;
}

这个代码比我们的代码更好，你只需要添加2个库:javax. servlet .jar和org.mortbay.jetty.jar。

类码头:

package jetty;

import java.util.logging.Level;
import java.util.logging.Logger;
import org.mortbay.http.SocketListener;
import org.mortbay.jetty.Server;
import org.mortbay.jetty.servlet.ServletHttpContext;

public class Jetty {

    public static void main(String[] args) {
        try {
            Server server = new Server();
            SocketListener listener = new SocketListener();      

            System.out.println("Max Thread :" + listener.getMaxThreads() + " Min Thread :" + listener.getMinThreads());

            listener.setHost("localhost");
            listener.setPort(8070);
            listener.setMinThreads(5);
            listener.setMaxThreads(250);
            server.addListener(listener);            

            ServletHttpContext context = (ServletHttpContext) server.getContext("/");
            context.addServlet("/MO", "jetty.HelloWorldServlet");

            server.start();
            server.join();

        /*//We will create our server running at http://localhost:8070
        Server server = new Server();
        server.addListener(":8070");

        //We will deploy our servlet to the server at the path '/'
        //it will be available at http://localhost:8070
        ServletHttpContext context = (ServletHttpContext) server.getContext("/");
        context.addServlet("/MO", "jetty.HelloWorldServlet");

        server.start();
        */

        } catch (Exception ex) {
            Logger.getLogger(Jetty.class.getName()).log(Level.SEVERE, null, ex);
        }

    }
} 

Servlet类:

package jetty;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HelloWorldServlet extends HttpServlet
{
    @Override
    protected void doGet(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws ServletException, IOException
    {
        String appid = httpServletRequest.getParameter("appid");
        String conta = httpServletRequest.getParameter("conta");

        System.out.println("Appid : "+appid);
        System.out.println("Conta : "+conta);

        httpServletResponse.setContentType("text/plain");
        PrintWriter out = httpServletResponse.getWriter();
        out.println("Hello World!");
        out.close();
    }
}

检出简单。它是一个非常简单的嵌入式服务器，内置了对各种操作的支持。我特别喜欢它的线程模型..

神奇的!

以上所有的回答关于单主线程请求处理器的细节。

设置:

 server.setExecutor(java.util.concurrent.Executors.newCachedThreadPool());

允许多个请求服务通过多个线程使用执行器服务。

因此，结束代码将如下所示:

import java.io.IOException;
import java.io.OutputStream;
import java.net.InetSocketAddress;
import com.sun.net.httpserver.HttpExchange;
import com.sun.net.httpserver.HttpHandler;
import com.sun.net.httpserver.HttpServer;
public class App {
    public static void main(String[] args) throws Exception {
        HttpServer server = HttpServer.create(new InetSocketAddress(8000), 0);
        server.createContext("/test", new MyHandler());
        //Thread control is given to executor service.
        server.setExecutor(java.util.concurrent.Executors.newCachedThreadPool());
        server.start();
    }
    static class MyHandler implements HttpHandler {
        @Override
        public void handle(HttpExchange t) throws IOException {
            String response = "This is the response";
            long threadId = Thread.currentThread().getId();
            System.out.println("I am thread " + threadId );
            response = response + "Thread Id = "+threadId;
            t.sendResponseHeaders(200, response.length());
            OutputStream os = t.getResponseBody();
            os.write(response.getBytes());
            os.close();
        }
    }
}
