webservice用cxf发布REST

1、新建一个java项目

2、导入cxf相关的jar包，并部署到项目中

3、bean类

 package com.xiaostudy;

 import javax.xml.bind.annotation.XmlRootElement;

 /**
  * @desc bean类
  * @author xiaostudy
  *
  */
 @XmlRootElement(name = "user")
 public class User {

     private int id;
     private String name;
     private int age;

     public int getId() {
         return id;
     }

     public void setId(int id) {
         this.id = id;
     }

     public String getName() {
         return name;
     }

     public void setName(String name) {
         this.name = name;
     }

     public int getAge() {
         return age;
     }

     public void setAge(int age) {
         this.age = age;
     }

 }

4、服务接口

 package com.xiaostudy;

 import java.util.List;

 import javax.jws.WebService;
 import javax.ws.rs.GET;
 import javax.ws.rs.POST;
 import javax.ws.rs.Path;
 import javax.ws.rs.PathParam;
 import javax.ws.rs.Produces;
 import javax.ws.rs.core.MediaType;

 /**
  * @desc 服务器接口
  * @author xiaostudy
  *
  */
 @WebService//表示发布服务
 @Path("/user")//类访问数据的路径
 public interface Test_service {

     @GET//访问方式
     //"application/json;charset=utf-8"是JSon数据类型，MediaType.APPLICATION_XML是xml数据类型
     //两个同时用的话，get访问方式默认是xml数据类型，post默认是JSon数据类型，访问的时候可以自己设置数据类型
     @Produces({"application/json;charset=utf-8",MediaType.APPLICATION_XML})
     @Path("/getUser/{name}")//方法访问数据的路径，{}表示是参数
     public User getUser(@PathParam("name")String name);//设置参数名称

     @GET//访问方式
     @Produces("application/json;charset=utf-8")//只用JSon数据类型
     @Path("/getUserList/{names}")//方法访问数据的路径，{}表示是参数
     public List<User> getUserList(@PathParam("names")String... names);//设置参数名称

 }

5、服务接口实现类

 package com.xiaostudy;

 import java.util.List;
 import java.util.Vector;

 /**
  * @desc 服务器接口实现类
  * @author xiaostudy
  *
  */
 public class Test_serviceImpl implements Test_service {

     /**
      * @desc 处理客户端的数据，并返回数据
      * @param name 参数
      * @return String 返回数据类型
      */
     @Override
     public User getUser(String name) {
         User user = new User();
         user.setId(1111);
         user.setName(name);
         user.setAge(23);
         return user;
     }

     @Override
     public List<User> getUserList(String... names) {
         List<User> list = new Vector<User>();
         for(int i = 0; i < names.length; i++) {
             User user = new User();
             user.setId(1+i);
             user.setName(names[i]);
             user.setAge(23+i);
             list.add(user);
         }
         return list;
     }

 }

6、开启服务

 package com.xiaostudy;

 import org.apache.cxf.interceptor.LoggingInInterceptor;
 import org.apache.cxf.interceptor.LoggingOutInterceptor;
 import org.apache.cxf.jaxrs.JAXRSServerFactoryBean;

 /**
  * @desc 开始服务器类
  * @author xiaostudy
  *
  */
 public class MyService {

     public static void main(String[] args) {
         // JaxWsServerFactoryBean发布服务
         JAXRSServerFactoryBean jAXRSServerFactoryBean = new JAXRSServerFactoryBean();
         // 设置服务实现类
         jAXRSServerFactoryBean.setServiceBean(new Test_serviceImpl());
         //设置资源类
         jAXRSServerFactoryBean.setResourceClasses(Test_serviceImpl.class);
         // 设置服务地址
         jAXRSServerFactoryBean.setAddress("http://127.0.0.1:9998/test");
         // 拦截器
         jAXRSServerFactoryBean.getInInterceptors().add(new LoggingInInterceptor());
         jAXRSServerFactoryBean.getOutInterceptors().add(new LoggingOutInterceptor());

         // 发布服务
         jAXRSServerFactoryBean.create();

     }

 }

7、测试是否发布成功，wsdl是w3c标准，wadl是REST的

结合spring整合发布

就是把这java的main发布转到Tomcat服务器上

applicationContext.xml

 <?xml version="1.0" encoding="utf-8"?>
 <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:jaxws="http://cxf.apache.org/jaxws"
