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
@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);
}
}
接下来是服务提供类，PhopuRestfulService.java
@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
cxf-phopu org.apache.cxf.transport.servlet.CXFServlet cxf-phopu /services/*
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：
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
public static String getReturnStr(HttpResponse response) throws Exception {
String result = null;
BufferedInputStream buffer = new BufferedInputStream(response.getEntity().getContent());
byte[] bytes = new byte[1024];
int line = 0;
StringBuilder builder = new StringBuilder();
while ((line = buffer.read(bytes)) != -1) {
builder.append(new String(bytes, 0, line, HTTP_SERVER_ENCODING));
}
result = builder.toString();
return result;
}
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。
