webservice通信调用天气预报接口实例

一：环境搭建

1：新建一个java project工程weatherInf

2：引入相应的jar包

activation.jar
axis-ant.jar
axis.jar
commons-discovery-0.2.jar
commons-logging-1.0.4.jar
jaxrpc.jar
log4j-1.2.8.jar
mail.jar
saaj.jar
wsdl4j-1.5.1.jar

下载axis 1.4 src压缩包，解压后到webapp/web-info/lib下取包，具体路径如下：

http://download.csdn.net/detail/yyg64/5351114

其中mail.jar 以及 activation.jar 可到如下路径下载：

http://download.csdn.net/detail/dbhunter/398258

3：将天气预报接口wsdl文件拷贝到src目录下

http://www.webxml.com.cn/WebServices/WeatherWebService.asmx?wsdl

二：目录结构

三：根据wsdl文件生成客户端代码

wsdl文件——右键——web services——Generate Client，然后一路next到finish。

会生成如下客户端代码：

四：测试代码

/**

package com.paic.services;

import java.rmi.RemoteException;

import javax.xml.rpc.ServiceException;

import cn.com.WebXml.WeatherWebServiceLocator;
import cn.com.WebXml.WeatherWebServiceSoapStub;

/**

 */
public class TestWeather {
    public static void main(String[] args) throws ServiceException,
            RemoteException {
        WeatherWebServiceLocator locator = new WeatherWebServiceLocator();
        WeatherWebServiceSoapStub service = (WeatherWebServiceSoapStub) locator
                .getPort(WeatherWebServiceSoapStub.class);
        invokeGetSupportProvince(service);
        System.out.println("...................");
        invokeGetSupportCity(service);
        invokeGetWeatherByOneCity(service);
    }

    // 调用获取支持的省份、州接口
    public static void invokeGetSupportProvince(
            WeatherWebServiceSoapStub service) throws RemoteException {
        String[] provices = service.getSupportProvince();
        System.out.println("总共" + provices.length + "个");
        int count = 0;
        for (String str : provices) {
            if (0 != count && count % 5 == 0) {
                System.out.println();
            }
            System.out.print(str + "	");
            count++;
        }
    }

    // 调用获取支持查询某个省份内的城市接口
    public static void invokeGetSupportCity(WeatherWebServiceSoapStub service)
            throws RemoteException {
        String provinceName = "江苏";
        String[] cities = service.getSupportCity(provinceName);
        System.out.println("总共" + cities.length + "个市");
        for (int i = 0; i < cities.length; i++) {
            if (0 != i && i % 5 == 0) {
                System.out.println();
            }
            System.out.print(cities[i] + "	");
        }
    }

    // 调用查询某个城市天气的接口
    public static void invokeGetWeatherByOneCity(
            WeatherWebServiceSoapStub service) throws RemoteException {
        String cityName = "南京";
        String[] weatherInfo = service.getWeatherbyCityName(cityName);
        for (String str : weatherInfo) {
            System.out.println(str);
        }
    }
}

五：得到结果
