Java 调用天气Webservice详解及实例代码

java调用天气Webservice的小应用

废话不多说,直接贴代码：

CityReq.java

package com.weather;

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

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;

}

}
