2. Create a service interface

Package Com.baidu.service;import Javax.ws.rs.consumes;import Javax.ws.rs.delete;import javax.ws.rs.GET;import Javax.ws.rs.post;import Javax.ws.rs.put;import Javax.ws.rs.path;import Javax.ws.rs.pathparam;import Javax.ws.rs.produces;import javax.ws.rs.queryparam;import Com.baidu.domain.User; @Path ("/userservice")//server access resource path  @Produces ("*/*")//The return value of the Generate method//Specifies whether the generated format data is returned to the client public interface UserService {//@GET query @PUT modification @POST increased @DELETE Delete the @post @Path ("/saveuser") @Consumes ({"Application/xml", "Application/json"})//The parameters of the consumption method public void Saveuser (user user @DELETE @path ("/deleteuser") @Consumes ({"Application/xml", "Application/json"}) public void DeleteUser (@QueryParam (value= "id") Integer ID), @PUT @path ("/updateuser") @Consumes ({"Application/xml", "Application/json"}) public void UpdateUser (User User), @GET @path ("/queryuser/{id}") @Consumes ({"Application/xml", "Application/json"}) @Produces ({"Application/xml "," Application/json "}) public User Queryuser (@PathParam (value=" id ") Integer ID);}

@Path	Server Access Resource Path
@Produces	Specifies the amount of data format generated in that format to return to the client
@Consumes	Specify the data format to receive
@POST	Specifies that the method is saved (saved)
@DELETE	Specifies that the method is deleted
@PUT	Specifies that the method is modified
@GET	Specifies that the method is a query

　　

3. Create a Service implementation class

Package Com.baidu.service.imp;import Com.baidu.domain.user;import Com.baidu.service.userservice;public class Userserviceimp implements UserService {public void Saveuser (user user) {System.out.println ("Saveuser" +user);} public void DeleteUser (Integer id) {SYSTEM.OUT.PRINTLN ("DeleteUser ID:" +id);} public void UpdateUser (user user) {System.out.println ("UpdateUser User:" +user); Public User Queryuser (Integer id) {SYSTEM.OUT.PRINTLN ("id"), if (id==1) {System.out.println (ID); User U=new User (); U.setid (ID); U.setname ("Zhangsan"); return u;} return null;}}

4. Publishing services

Package Com.baidu.publish;import Org.apache.cxf.jaxrs.jaxrsserverfactorybean;import Com.baidu.domain.user;import Com.baidu.service.userservice;import Com.baidu.service.imp.userserviceimp;public class PublishService {public static void Main (string[] args) {userservice us=new userserviceimp (); Jaxrsserverfactorybean serverfactorybean=new Jaxrsserverfactorybean (); Serverfactorybean.setresourceclasses ( User.class); Serverfactorybean.setservicebean (US), serverfactorybean.setaddress ("http://localhost:8099"); Serverfactorybean.create ();}}

Pom.xml file for test project

Testing a published Service

public static void Main (string[] args) {//save//USER user = new user ();//User.setid (1);//User.setname ("Zhangsan");//Web Client.create ("Http://localhost:8099/userService/saveUser")//. Type (Mediatype.application_xml). Post (user);//delete/ /Webclient.create ("http://localhost:8099/userService/deleteUser?id=1"). Type (mediatype.application_xml). Delete ( );//modify//USER user = new user ()//User.setid (1);//User.setname ("Zhangsan");//Webclient.create ("http://localhost : 8099/userservice/deleteuser "). Type (Mediatype.application_xml). put (user);/  /query//user User =webclient.create ( "HTTP://LOCALHOST:8099/USERSERVICE/QUERYUSER/1")//. Accept (Mediatype.application_xml). get (User.class);// SYSTEM.OUT.PRINTLN (user);}

User class

Package Com.baidu.domain;import Javax.xml.bind.annotation.xmlelement;import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement (name= "User") public class User {private Integer id;private String name;public Integer getId () {return Id;} public void SetId (Integer ID) {id = ID;} Public String GetName () {return name;} public void SetName (String name) {this.name = name;} @Overridepublic String toString () {return "User [id=" + Id + ", name=" + name + "]";}}
