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。

@XmlRootElement(name="User")public class User { private String userName; private String sex; private int age; public User(String userName, String sex, int age) { super(); this.userName = userName; this.sex = sex; this.age = age; } public User() { super(); } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getSex() { return sex; } public void setSex(String sex) { this.sex = sex; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public static void main(String[] args) throws IOException { System.setProperty("http.proxySet", "true"); System.setProperty("http.proxyHost", "192.168.1.20"); System.setProperty("http.proxyPort", "8080"); URL url = new URL("http://www.baidu.com"); URLConnection con =url.openConnection(); System.out.println(con); }} |

@Path("/phopuService")public class PhopuRestfulService { Logger logger = Logger.getLogger(PhopuRestfulServiceImpl.class); @GET @Produces(MediaType.APPLICATION_JSON) //指定返回数据的类型 json字符串 //@Consumes(MediaType.TEXT_PLAIN) //指定请求数据的类型 文本字符串 @Path("/getUser/{userId}") public User getUser(@PathParam("userId")String userId) { this.logger.info("Call getUser() method...."+userId); User user = new User(); user.setUserName("中文"); user.setAge(26); user.setSex("m"); return user; } @POST @Produces(MediaType.APPLICATION_JSON) //指定返回数据的类型 json字符串 //@Consumes(MediaType.TEXT_PLAIN) //指定请求数据的类型 文本字符串 @Path("/getUserPost") public User getUserPost(String userId) { this.logger.info("Call getUserPost() method...."+userId); User user = new User(); user.setUserName("中文"); user.setAge(26); user.setSex("m"); return user; }} |
web.xml配置，跟soap协议的接口一样

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：

public static void getWeatherPostTest() throws Exception{ String url = "http://localhost:8080/phopu/services/phopuService/getUserPost"; HttpClient httpClient = HttpClients.createSystem(); //HttpGet httpGet = new HttpGet(url); //接口get请求，post not allowed HttpPost httpPost = new HttpPost(url); httpPost.addHeader(CONTENT_TYPE_NAME, "text/plain"); StringEntity se = new StringEntity("101010500"); se.setContentType("text/plain"); httpPost.setEntity(se); HttpResponse response = httpClient.execute(httpPost); int status = response.getStatusLine().getStatusCode(); log.info("[接口返回状态吗] : " + status); String weatherInfo = ClientUtil.getReturnStr(response); log.info("[接口返回信息] : " + weatherInfo); } |
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

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。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。
