WebService开发方法介绍

来源：互联网发布：闪光灯软件哪个好编辑：程序博客网时间：2024/06/07 02:13

1.使用客户端生成代码

a.在命令行或终端使用wsimport生成客户端的调用

wsimport  -s xxx  http://127.0.0.1:12345/weathers?wsdl

xxx为本地存放生成代码的目录
- b.使用生成代码调用WebService服务端

      //创建服务视图对象      WeatherInterfaceImplService s=new WeatherInterfaceImplService();      //通过服务试图得到PortType      WeatherInterfaceImpl weatherInterfaceImplPort = s.getWeatherInterfaceImplPort();      //调用方法      weatherInterfaceImplPort.queryWeather("dasd");

2.使用JAXWS标准方法(Service)调用

a.在命令行或终端使用wsimport生成客户端的调用
b.在命令行或终端使用wsimport生成客户端的调用

    //wsdl地址    URL wsdldocument=new URL("http://127.0.0.1:54321/weathers?wsdl");    //第一个参数是命名空间，第二个参数是Service名称    QName qName=new QName("http://nio/","WeatherInterfaceImplService");    //创建服务    Service service =Service.create(wsdldocument, qName);    //得到portType    WeatherInterfaceImpl port = service.getPort(WeatherInterfaceImpl.class);    port.queryWeather("广东");

3.模拟http客户端调用webservice服务

使用HttpURLConnection或apache的Httpclient模拟http请求，调用webservice。
注意：使用此方法不需要生成客户端调用代码。
下面是一个例子供大家参考、
