我正在实现一个SOAP
Web 服务GAE
。由于GAE
不支持JAX-WS
我选择了这种方式,这基本上是我自己从一个servlet构建soap请求和响应。
一切正常,但我怎样才能实现返回 wsdl 描述http://myurl/MyService?wsdl
?
我想我必须实现GET
我的 servlet 的方法,但是如何实现呢?
我附上了一个工作实现。请注意,它基于 Servlet 3.0 规范。如果您使用的是 2.5,注释将不起作用。
import java.io.FileInputStream;
import java.io.IOException;

@WebServlet(name="MyWSServlet", urlPatterns={"/MyService"})
public class MyWSServlet extends HttpServlet {
private static final long serialVersionUID = 3605874163075522777L;
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
boolean requestForWSDL = false;
Enumeration<String> params = req.getParameterNames();
while (params.hasMoreElements()) {
if ("wsdl".equalsIgnoreCase(params.nextElement())) {
requestForWSDL = true;
}
}
if (requestForWSDL) {
FileInputStream wsdlInputStream = new FileInputStream(req.getServletContext().getRealPath("/wsdl/TemperatureService.wsdl"));
byte[] buffer = new byte[1024];
resp.setContentType("application/xml");
int bytesRead = 0;
while ((bytesRead = wsdlInputStream.read(buffer)) != -1) {
resp.getOutputStream().write(buffer, 0, bytesRead);
}
wsdlInputStream.close();
resp.getOutputStream().flush();
}
}
}
