5. webservice通信调用天气预报接口实例

转自：https://blog.csdn.net/xiejuan6105/article/details/78452605

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

 8 import javax.xml.rpc.ServiceException;

17 public class TestWeather {
18     public static void main(String[] args) throws ServiceException,
19             RemoteException {
20         WeatherWebServiceLocator locator = new WeatherWebServiceLocator();
21         WeatherWebServiceSoapStub service = (WeatherWebServiceSoapStub) locator
22                 .getPort(WeatherWebServiceSoapStub.class);
23         invokeGetSupportProvince(service);
24         System.out.println("...................");
25         invokeGetSupportCity(service);
26         invokeGetWeatherByOneCity(service);
27     }
28
29     // 调用获取支持的省份、州接口
30     public static void invokeGetSupportProvince(
31             WeatherWebServiceSoapStub service) throws RemoteException {
32         String[] provices = service.getSupportProvince();
33         System.out.println("总共" + provices.length + "个");
34         int count = 0;
35         for (String str : provices) {
36             if (0 != count && count % 5 == 0) {
37                 System.out.println();
38             }
39             System.out.print(str + "\t");
40             count++;
41         }
42     }
43
44     // 调用获取支持查询某个省份内的城市接口
45     public static void invokeGetSupportCity(WeatherWebServiceSoapStub service)
46             throws RemoteException {
47         String provinceName = "江苏";
48         String[] cities = service.getSupportCity(provinceName);
49         System.out.println("总共" + cities.length + "个市");
50         for (int i = 0; i < cities.length; i++) {
51             if (0 != i && i % 5 == 0) {
52                 System.out.println();
53             }
54             System.out.print(cities[i] + "\t");
55         }
56     }
57
58     // 调用查询某个城市天气的接口
59     public static void invokeGetWeatherByOneCity(
60             WeatherWebServiceSoapStub service) throws RemoteException {
61         String cityName = "南京";
62         String[] weatherInfo = service.getWeatherbyCityName(cityName);
63         for (String str : weatherInfo) {
64             System.out.println(str);
65         }
66     }
67 }

五：得到结果
