REST的例子
与web service类似,REST利用一个更加接近http的协议传递数据。
请求的目的地即是一个URI,数据的格式可以是XML、JSON或者是纯文本。
下面是一个在myeclipse 8.6上的REST小例子,还很不完善先记录下来。
部署REST服务:web service project, 选择了REST的web service
package com.test; import javax.ws.rs.Consumes; import javax.ws.rs.GET; import javax.ws.rs.POST; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import com.sun.jersey.spi.resource.Singleton; @Produces("text/plain") @Path("customers") @Singleton public class Interface { @GET public String getCustomers(){ return "getCustomers all"; } @GET @Path("{id}") public String getCustomer(@PathParam("id") String uid) { return "your id is "+ uid; } }
客户端调用:java project
package com.app; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.URL; public class app { /** * @param args */ public static void main(String[] args) throws MalformedURLException { // TODO Auto-generated method stub //实例一个URL资源 URL url = null; try { url = new URL("http://localhost:8080/java_ws01/services/customers"); //url = new URL("http://localhost:8080/java_ws01/services/customers/321"); HttpURLConnection connet; connet = (HttpURLConnection) url.openConnection(); if(connet.getResponseCode() != 200){ throw new IOException(connet.getResponseMessage()); } //将返回的值存入到String中 BufferedReader brd = new BufferedReader(new InputStreamReader(connet.getInputStream())); System.out.println(brd.readLine()); connet.disconnect(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
