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
View Code
1 package com.test;
2
3 import javax.ws.rs.Consumes;
4 import javax.ws.rs.GET;
5 import javax.ws.rs.POST;
6 import javax.ws.rs.Path;
7 import javax.ws.rs.PathParam;
8 import javax.ws.rs.Produces;
9 import com.sun.jersey.spi.resource.Singleton;
10
11 @Produces("text/plain")
12 @Path("customers")
13 @Singleton
14 public class Interface {
15
16 @GET
17 public String getCustomers(){
18 return "getCustomers all";
19 }
20 @GET
21 @Path("{id}")
22 public String getCustomer(@PathParam("id") String uid) {
23 return "your id is "+ uid;
24 }
25 }
客户端调用：java project

21 //url = new URL("http://localhost:8080/java_ws01/services/customers/321");
22 HttpURLConnection connet;
23 connet = (HttpURLConnection) url.openConnection();
24 if(connet.getResponseCode() != 200){
25 throw new IOException(connet.getResponseMessage());
26 }
27 //将返回的值存入到String中
28 BufferedReader brd = new BufferedReader(new InputStreamReader(connet.getInputStream()));
29
30 System.out.println(brd.readLine());
31
32 connet.disconnect();
33 } catch (IOException e) {
34 // TODO Auto-generated catch block
35 e.printStackTrace();
36 }
