[Resteasy-developers] Fwd: Custom HTTP verbs in RESTeasy with Spring
|

Ah, ok. So, I stand corrected. RESTeasy *can* do this. It's the Spring
RequestDispatcher that was barfing on the unfamiliar method. For anyone
else wanting to commit this sin...
I created the following controller to see what would actually be handled by
Spring itself:
@Controller
@RequestMapping("/reset")
public class ResetController {
@RequestMapping
public void reset(final HttpServletRequest request, final
HttpServletResponse response) throws Exception {
final String method = request.getMethod();
final PrintWriter writer = response.getWriter();
writer.write(String.format("<html><body><p>%s</p></body></html>", method));
writer.flush();
}
}
Contrary to my expectation that failed with the Tomcat error message. So a
little rummaging produced the following Spring forum posting:
http://forum.springsource.org/showthread.php?53472-DispatcherServlet-ServletWrappingController-with-JackRabbit-SimpleWevdavServlet&p=178514#post178514
I pretty much cribbed that as follows:
public class PromiscuousDispatcherServlet extends DispatcherServlet {
private static final long serialVersionUID = 3006276017308264614L;
@Override
protected void service(final HttpServletRequest req, final
HttpServletResponse resp) throws ServletException, java.io.IOException {
try {
doService(req, resp);
} catch (final Exception e) {
throw new ServletException("Failure during servlet dispatch", e);
}
}
}
By substituting the PromiscuousDispatcherServlet for the real Spring ones I
now find my @RESET annotation is honoured in the RESTeasy controller.
Now to get a cuppa tea and consider the morality of actually using it... :-)
Thanks.
