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;

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;
  }

  
}
