                </plugin>
            </plugins>
        </pluginManagement>
    </build>

第二步：创建webservice接口和实现类

@WebService
public interface WeatherService {

    public String queryWeather(String cityName);


}
==
/**
 * @path : 用在方法上 代表当前服务方法的访问路径  ""
 * @GET  : 用在方法上 代表当前服务方法只能通过GET方式访问
 * @PathParam : 用来方法的参数上 代表获取请求路径中的参数  value属性用来书写路径的中参数的别名
 * @Produces  : 用在方法上  用来控制方法的响应类型
 */
@WebService
public class WeatherServiceImpl implements  WeatherService {


    @Override
    @POST
    @Path("/queryWeather/{cc}/")
    @Produces("text/plain;charset=UTF-8")
    public String queryWeather(@PathParam(value="cc") String cityName) {
        if("北京".equals(cityName)){
            return "晴......";
        }
        return "挺冷.....";
    }
}
=============================================================
@WebService
public interface UserWebService {

    Result save(User user);

    Result update(User user);

    Result delete(String id);

    Result findOne(String id);

    Result findAll();

}
===
@WebService
public class UserWebServiceImpl implements UserWebService {


    @Override
    @POST
    @Path("/save")
    @Produces("application/json;charset=UTF-8")
    public Result save(User user) {
        Result result = new Result();
        try {
            System.out.println("接收用户:" +user);
            result.setStatus(1);
        } catch (Exception e) {
            e.printStackTrace();
            result.setStatus(0);
            result.setMessage(e.getMessage());
        }
        return result;
    }

    @Override
    @PUT
    @Path("/update")
    @Produces("application/json;charset=UTF-8")
    public Result update(User user) {
        Result result = new Result();
        try {
            System.out.println("更新的用户信息:" +user);
            result.setStatus(1);
        } catch (Exception e) {
            e.printStackTrace();
            result.setStatus(0);
            result.setMessage(e.getMessage());
        }
        return result;
    }

    @Override
    @DELETE
    @Path("/delete/{id}/")
    @Produces("application/json;charset=UTF-8")
    public Result delete(@PathParam("id") String id) {
        Result result = new Result();
        try {
            System.out.println("删除的对象的id: "+id);
            result.setStatus(1);
        } catch (Exception e) {
            e.printStackTrace();
            result.setStatus(0);
            result.setMessage(e.getMessage());
        }
        return result;
    }

    @Override
    @GET
    @Path("/findOne/{id}/")
    @Produces("application/json;charset=UTF-8")
    public Result findOne(@PathParam("id") String id) {
        Result result;
        try {
            System.out.println("查询对象的id: "+id);
            User user = new User(id, "小黑", 23, new Date());
            result  = new Result();
            result.getResult().add(user);
            result.setStatus(1);
        } catch (Exception e) {
            e.printStackTrace();
            result = new Result();
            result.setStatus(0);
            result.setMessage(e.getMessage());
        }
        return result;
    }

    @Override
    @GET
    @Path("/findAll")
    @Produces("application/json;charset=UTF-8")
    public Result findAll() {
        Result result = new Result();
        try {
            System.out.println("查询所有对象信息.......");
            List<User> users = new ArrayList<>();
            users.add(new User("21","小三",23,new Date()));
            users.add(new User("22","小四",23,new Date()));
            users.add(new User("23","小五",23,new Date()));
            users.add(new User("24","小六",23,new Date()));
            users.add(new User("25","小七",23,new Date()));
            result.getResult().addAll(users);
            result.setStatus(1);
        } catch (Exception e) {
            e.printStackTrace();
            result.setStatus(0);
            result.setMessage(e.getMessage());
        }
        return result;
    }
}

第三步：配置spring-cxf.xml配置文件，通过restful方式发布服务

<?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:jaxrs="http://cxf.apache.org/jaxrs"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://cxf.apache.org/jaxrs http://cxf.apache.org/schemas/jaxrs.xsd">




    <!--注册服务实现类-->
    <bean id="weatherService" class="com.baizhi.restful.webservice.WeatherServiceImpl"></bean>

    <bean id="userWebService" class="com.baizhi.restful.webservice.UserWebServiceImpl"></bean>

    <!--使用restful形式发布服务jaxws  jaxrs

        服务地址:http://localhost:8989/cxf_restful_webservice_server/cxf/ws/queryWeather/北京/
    -->
    <jaxrs:server address="/ws" serviceClass="com.baizhi.restful.webservice.WeatherService">
        <jaxrs:serviceBeans>
            <ref bean="weatherService"></ref>
        </jaxrs:serviceBeans>
    </jaxrs:server>



    <jaxrs:server address="/userservice" serviceClass="com.baizhi.restful.webservice.UserWebService">
        <jaxrs:serviceBeans>
            <ref bean="userWebService"/>
        </jaxrs:serviceBeans>
        <!--配置底层转换json的工具包-->
        <jaxrs:providers>
            <bean class="com.alibaba.fastjson.support.jaxrs.FastJsonProvider"/>
        </jaxrs:providers>
    </jaxrs:server>




</beans>

第四步：在spring配置文件中引入xcf子配置文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">






    <!--引入子配置文件-->
    <import resource="classpath:spring-cxf.xml"/>
</beans>

第五步：配置web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  
  
  <!--初始化工厂的配置文件-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring-basic.xml</param-value>
  </context-param>
  
  <!--配置工厂启动的监听器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <!--配置CXF的Servlet-->
  <servlet>
    <servlet-name>cxf</servlet-name>
    <servlet-class>org.apache.cxf.transport.servlet.CXFServlet</servlet-class>
  </servlet>
  
  <servlet-mapping>
    <servlet-name>cxf</servlet-name>
    <url-pattern>/cxf/*</url-pattern>
  </servlet-mapping>
</web-app>

第六步：配置tomcat启动项目

 第七步：访问swdl    

地址：http://localhost:9999/cxf_restful_webservice_server/cxf/ws/queryWeather/北京/
