Java調用天氣Webservice的小應用

廢話不多說,直接貼代碼：

 

CityReq.java

package com.weather;

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="getWeatherbyCityName",namespace="http://WebXml.com.cn/")
public class CityReq {

    private String theCityName;

    public String getTheCityName() {
        return theCityName;
    }

    @XmlElement(name="theCityName",namespace="http://WebXml.com.cn/")
    public void setTheCityName(String theCityName) {
        this.theCityName = theCityName;
    }

    
}
