REST实现(Spring下实现+JDK6机制实现)

来源：互联网发布：sql developer输出数据编辑：程序博客网时间：2024/05/22 15:28

1、Spring下实现

见：Spring4搭建+REST在Spring上搭建 http://blog.csdn.net/textboy/article/details/51141436

2、利用JDK 6机制实现

这种方式更为灵活，可以设置最大接受请求数和线程数（在Spring下...还真不知在哪里可以设这些参数）

httpServer、httpHandler

import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.net.InetSocketAddress;import java.util.concurrent.Executors;import com.sun.net.httpserver.HttpExchange;import com.sun.net.httpserver.HttpHandler;import com.sun.net.httpserver.HttpServer;import com.sun.net.httpserver.spi.HttpServerProvider;/* * http://sunnylocus.iteye.com/blog/460945 * http://www.360doc.com/content/12/0528/17/2569758_214300573.shtml * http://outofmemory.cn/code-snippet/35680/Java-HTTP-fuwuqi-example * 异步AIO：http://blog.csdn.net/zhongweijian/article/details/8005444 */public class MyHttpServerJavaEE6 {//启动服务，监听来自客户端的请求    public static void httpserverService() throws IOException {        HttpServerProvider provider = HttpServerProvider.provider();        HttpServer httpserver =provider.createHttpServer(new InetSocketAddress(6666), 100);//监听端口6666,能同时接 受100个请求        httpserver.createContext("/myApp", new MyHttpHandler());        //httpserver.setExecutor(null); //使用单线程        httpserver.setExecutor(Executors.newFixedThreadPool(5));        httpserver.start();        System.out.println("server started");    }    //Http请求处理类    static class MyHttpHandler implements HttpHandler {        public void handle(HttpExchange httpExchange) throws IOException {            String responseMsg = "ok";   //响应信息                        InputStream in = httpExchange.getRequestBody(); //获得输入流            BufferedReader reader = new BufferedReader(new InputStreamReader(in));            String temp = null;            while((temp = reader.readLine()) != null) {                System.out.println("client request:"+temp);            }                        httpExchange.sendResponseHeaders(200, responseMsg.length()); //设置响应头属性及响应信息的长度            OutputStream out = httpExchange.getResponseBody();  //获得输出流            out.write(responseMsg.getBytes());            out.flush();            httpExchange.close();        }    }        public static void main(String[] args) throws IOException {        httpserverService();    }}

httpClient

import java.net.URI;import org.springframework.web.client.RestClientException;import org.springframework.web.client.RestTemplate;public class SpringRestTestClient {//public static final String REST_SERVICE_URI = "http://localhost:8080/springPoC1/service";public static final String REST_SERVICE_URI = "http://localhost:6666/myApp";private static void listAllUsers(){RestTemplate restTemplate = new RestTemplate();String jsonParam = "{\"name\":\"Aiya\"}";try {URI uri = restTemplate.postForLocation(REST_SERVICE_URI+"/user1", jsonParam, String.class);if (null != uri){System.out.println("Location : "+uri.toASCIIString());} else {System.out.println("uri is null~");}String result = restTemplate.postForObject(REST_SERVICE_URI+"/user1", jsonParam, String.class);System.out.println("testUser~" + result);} catch (RestClientException e) {e.printStackTrace();}}public static void main(String[] args) {listAllUsers();}}
