简单实现

1.创建接口和实现类  （模拟实现查询天气）

接口：

package com.learning.weather;

/**
 *
 * weather 接口 ：实现模拟wsdl
 */
public interface WeatherInterface {

    /**
     * 查询天气
     * @param name
     * @return
     */
    public String queryWeather(String name);
}

实现类：

package com.learning.weather;

import javax.jws.WebService;

@WebService
public class WeatherInterfaceImpl implements WeatherInterface {

    @Override
    public String queryWeather(String name) {
        System.out.println("查询天气"+ name);
        return "nihao ";
    }
}

main方法测试，开启服务：

package com.learning.weather;

import javax.xml.ws.Endpoint;

public class TestMain {

    public static void main(String[] args) {

        String address="Http://127.0.0.1:1234/weather";
        Object implementor=new WeatherInterfaceImpl();
        Endpoint.publish(address, implementor);
    }

}

访问 Http://127.0.0.1:1234/weather，点击wsdl

出现以下页面

在src目录下 执行wsimport命令  ：  wsimport -p com.learning.client -s  .  http://127.0.0.1:1234/weather?wsdl

src下刷新出现新的包com.learning.client

写客户端程序

package com.learning.client;

public class TestMain {

    public static void main(String[] args) {
        //1.创建服务视图
        WeatherInterfaceImplService weatherInterfaceImplService =new WeatherInterfaceImplService();
        //2.得到实现类
        WeatherInterfaceImpl weatherInterfaceImpl = weatherInterfaceImplService.getPort(WeatherInterfaceImpl.class);

        //发送数据
        String weather = weatherInterfaceImpl.queryWeather("湖北");
        System.out.println(weather);
    }
}

运行测试即可
