简单的webservice.docx

webservice实现有多种方式比如最常用的有axis框架，xfire框架，通过该框架可以发布wsdl接口，也可以实现webservice客户端，目前eclipse都有集成的插件，可以根据wsdl文件生成webservice客户端调用接口，但是这样部署的时候必须依赖框架的jar包，有时候可能因为环境等等原因，我们仅仅需要wsdl中的某一个接口，这时候可以通过http接口或socket接口直接发生xml数据，来调用服务端webservice服务，其实webservice底层还是发送xml数据，只是框架封装了对xml数据进行序列化与反序列化操作，下面以两个简单的例子说明http方式和socket方式。http实现webservice接口调用例子：c-sharpview plaincopy1. importjava.io.BufferedReader;2. importjava.io.IOException;3. importjava.io.InputStreamReader;4. importjava.io.OutputStreamWriter;5. importjava.io.UnsupportedEncodingException;6. .MalformedURLException;7. .URL;8. .URLConnection;9. 10. publicclassHttpPostTest11. voidtestPost(StringurlStr)12. try13.
