记得红薯大哥以前贴过一个mina的http服务器的实现，我就贴一个grizzly的。说起mina这个java网络通讯组件可是大名鼎鼎，说是高性能，的却性能强大。但是还有比它性能更强大的呢 就是这个 grizzly，glassfish就基于它。是个比mina性能更为强大的网络通讯组件，同样基于java NIO开发。我贴的代码是用它实现一个http服务器。

import org.glassfish.grizzly.http.server.HttpServer;

import org.glassfish.grizzly.http.server.NetworkListener;

import org.glassfish.grizzly.threadpool.ThreadPoolConfig;

HttpServer httpServer = new HttpServer();

NetworkListener networkListener = new NetworkListener("sample-listener", "127.0.0.1", 18888);

ThreadPoolConfig threadPoolConfig = ThreadPoolConfig

.defaultConfig()

.setCorePoolSize(1)

.setMaxPoolSize(1);

networkListener.getTransport().setWorkerThreadPoolConfig(threadPoolConfig);

httpServer.addListener(networkListener);

MyHttpHandler httpHandler = new MyHttpHandler();

httpServer.getServerConfiguration().addHttpHandler( httpHandler,new String[]{"/sample"});

try {

httpServer.start();

while(true){

}

} catch (IOException e) {

e.printStackTrace();

}

public class MyHttpHandler extends HttpHandler {

final ExecutorService complexAppExecutorService =

GrizzlyExecutorService.createInstance(

ThreadPoolConfig.defaultConfig()

.copy()

.setCorePoolSize(5)

.setMaxPoolSize(5));

public void service(final Request request, final Response response) throws Exception {

response.suspend(); // Instruct Grizzly to not flush response, once we exit the service(...) method

complexAppExecutorService.execute(new Runnable() { // Execute long-lasting task in the custom thread

public void run() {

try {

response.setContentType("text/plain");

// Simulate long lasting task

Thread.sleep(10000);

response.getWriter().write("Complex task is done!");

} catch (Exception e) {

response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR_500);

} finally {

response.resume();

}

}

});

}
