1）编写domain实体类

package com.domain;import java.io.Serializable;import javax.xml.bind.annotation.XmlElement;import javax.xml.bind.annotation.XmlRootElement;@XmlRootElement(name="UserInfo")public class User implements Serializable,Comparable
     
      {    /**     *      */    private static final long serialVersionUID = 1L;    private int id;    private String name;    private String email;    private String address;    public User(){}    @XmlElement    public int getId() {        return id;    }    public void setId(int id) {        this.id = id;    }    @XmlElement    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    @XmlElement    public String getEmail() {        return email;    }    public void setEmail(String email) {        this.email = email;    }    @XmlElement    public String getAddress() {        return address;    }    public void setAddress(String address) {        this.address = address;    }    @Override    public String toString() {        return this.name+","+this.email+","+this.address;    }    @Override    public int compareTo(User other) {        return this.id - other.id;    }}
     

2）业务处理接口

package com.service;import com.domain.User;public interface IUserService {
         public User getUserById(int id);}

3）业务处理实现类

package com.service;import com.domain.User;public class UserService implements IUserService{
         public User getUserById(int id){        User user = new User();        user.setId(1);        user.setName("Rickesy");        user.setAddress("china");        user.setEmail("Rickesy@163.com");        return user;    };}

3）Web Service接口

package com.rest;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.PathParam;import javax.ws.rs.Produces;import javax.ws.rs.core.MediaType;import com.domain.User;@Path(value="/")public interface IRESTService {    @GET    @Path("user/{id}")    @Produces({MediaType.APPLICATION_XML,        MediaType.APPLICATION_JSON})    public User getUserById(@PathParam("id") int id);}

4）Web Service实现类

package com.rest;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.PathParam;import javax.ws.rs.Produces;import javax.ws.rs.core.MediaType;import com.domain.User;import com.service.UserService;@Path(value="/")public class RESTService implements IRESTService{
         private User user;    private IUserService userService;    @GET    @Path("user/{id}")    @Produces({MediaType.APPLICATION_XML,        MediaType.APPLICATION_JSON})    public User getUserById(@PathParam("id") int id){        return userService.getUserById(id);    }    public IUserService getUserService() {        return userService;    }    public void setUserService(IUserService userService) {        this.userService = userService;    }    public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }   }

5）配置applicationContext.xml文件

6）配置web.xml

         
      
               org.springframework.web.context.ContextLoaderListener     
      
      
         
      
       contextConfigLocation
          
      
       classpath:applicationContext.xml
        
       
         
      
       CXFServlet
          
      
               org.apache.cxf.transport.servlet.CXFServlet    
      
     
            
      
       CXFServlet
          
      
       /*
      
     

7）客户端测试

package com.client;import javax.ws.rs.core.MediaType;import org.apache.cxf.jaxrs.client.WebClient;public class Client {    static WebClient client = WebClient.create(        "http://localhost:8080/RESTWebService/rest");    public static void main(String[] args) {        User user = client.path("/user/{id}",             1).accept(MediaType.APPLICATION_XML).get(User.class);        System.out.println(user);    }}
