webservice restful接口跟soap协议的接口实现大同小异，只是在提供服务的类/接口的注解上存在差异，具体看下面的代码，然后自己对比下就可以了。

用到的基础类

User.java

 

1 @XmlRootElement(name="User") 2 public class User { 3  4     private String userName; 5     private String sex; 6     private int age; 7      8     public User(String userName, String sex, int age) { 9         super();10         this.userName = userName;11         this.sex = sex;12         this.age = age;13     }14     15     public User() {16         super();17     }18 19     public String getUserName() {20         return userName;21     }22     public void setUserName(String userName) {23         this.userName = userName;24     }25     public String getSex() {26         return sex;27     }28     public void setSex(String sex) {29         this.sex = sex;30     }31     public int getAge() {32         return age;33     }34     public void setAge(int age) {35         this.age = age;36     }37     38     public static void main(String[] args) throws IOException {39         System.setProperty("http.proxySet", "true"); 40 41         System.setProperty("http.proxyHost",  "192.168.1.20"); 42 43         System.setProperty("http.proxyPort", "8080");44         45         URL url = new URL("http://www.baidu.com"); 46 47         URLConnection con =url.openConnection(); 48         49         System.out.println(con);50     }51 }

 

接下来是服务提供类，PhopuRestfulService.java

1 @Path("/phopuService") 2 public class PhopuRestfulService { 3  4  5     Logger logger = Logger.getLogger(PhopuRestfulServiceImpl.class); 6  7     @GET 8     @Produces(MediaType.APPLICATION_JSON) //指定返回数据的类型 json字符串 9     //@Consumes(MediaType.TEXT_PLAIN) //指定请求数据的类型 文本字符串10     @Path("/getUser/{userId}")11     public User getUser(@PathParam("userId")String userId) {12         this.logger.info("Call getUser() method...."+userId);13         User user = new User();14         user.setUserName("中文");15         user.setAge(26);16         user.setSex("m");17         return user;18     }19 20     @POST21     @Produces(MediaType.APPLICATION_JSON) //指定返回数据的类型 json字符串22     //@Consumes(MediaType.TEXT_PLAIN) //指定请求数据的类型 文本字符串23     @Path("/getUserPost")24     public User getUserPost(String userId) {25         this.logger.info("Call getUserPost() method...."+userId);26         User user = new User();27         user.setUserName("中文");28         user.setAge(26);29         user.setSex("m");30         return user;31     }32 }

web.xml配置，跟soap协议的接口一样

1 
     2     
     
      3         
      
       cxf-phopu
      4         
      
       org.apache.cxf.transport.servlet.CXFServlet
      5     
     6     
     
      7         
      
       cxf-phopu
      8         
      
       /services/*
      9     
     

Spring整合配置

 

 

客户端调用示例：

对于get方式的服务，直接在浏览器中输入 http://localhost:8080/phopu/services/phopuService/getUser/101010500 就可以直接看到返回的json字符串 

{"userName":"中文","sex":"m","age":26}

 

客户端调用代码如下：

1 public static void getWeatherPostTest() throws Exception{ 2         String url = "http://localhost:8080/phopu/services/phopuService/getUserPost"; 3         HttpClient httpClient = HttpClients.createSystem(); 4         //HttpGet httpGet = new HttpGet(url);  //接口get请求，post not allowed 5         HttpPost httpPost = new HttpPost(url); 6         httpPost.addHeader(CONTENT_TYPE_NAME, "text/plain"); 7         StringEntity se = new StringEntity("101010500"); 8         se.setContentType("text/plain"); 9         httpPost.setEntity(se);10         HttpResponse response = httpClient.execute(httpPost);11 12         int status = response.getStatusLine().getStatusCode();13         log.info("[接口返回状态吗] : " + status);14 15         String weatherInfo = ClientUtil.getReturnStr(response);16 17         log.info("[接口返回信息] : " + weatherInfo);18     }

客户端调用返回信息如下：

ClientUtil类是我自己封装的一个读取response返回信息的类，encoding是UTF-8

 

1 public static String getReturnStr(HttpResponse response) throws Exception { 2         String result = null; 3         BufferedInputStream buffer = new BufferedInputStream(response.getEntity().getContent()); 4         byte[] bytes = new byte[1024]; 5         int line = 0; 6         StringBuilder builder = new StringBuilder(); 7         while ((line = buffer.read(bytes)) != -1) { 8             builder.append(new String(bytes, 0, line, HTTP_SERVER_ENCODING)); 9         }10         result = builder.toString();11         return result;12     }

 

到这里，就介绍完了，大家手动去操作一下吧，有问题大家一块交流。
