An enhancement for servlet route mapping

[Michael]

Hi All,

 

I did a little enhancement for servlet route mapping for my own project, it could map a URL into a method within a servlet (Just like struts2) rather than a whole servlet. It works locally fine for me currently.

 

I just changed 3 source class a little very carefully. But I am still not sure whether I coded in a correct way. Especially under multi-thread situation.

 

If someone could take a review of these changes will be mush appreciated ! Many thanks!

 

I introduced 'at' to tell Guice bind the URL at the specified method:

 

return Guice.createInjector(new ServletModule() {
   @Override
   protected void configureServlets() {
    serve("/index").with(IndexServlet.class).at("index");
    serve("/index/update").with(IndexServlet.class).at("update");
    serve("/index/delete").with(IndexServlet.class).at("delete");
   }
  });

 

The method mush be follow :

 

public %AnyReturnType% %methodName%(HttpServletRequest request, HttpServletResponse response) [@Optional throws ServletException, IOException]

 

Here is an example of my servlet :

 

@Singleton
public class IndexServlet extends HttpServlet {
 private static final long serialVersionUID = 3594023761495055538L;
 
 public void index(HttpServletRequest request, HttpServletResponse response) {
  System.out.println("index");
 }
 public String update(HttpServletRequest request, HttpServletResponse response) {
  System.out.println("update");
  return "Hello";
 }
 public Object delete(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
  System.out.println("delete");
  return new Object();
 }
}

 

 

Attached is the source code I made changes. Many thanks again!

If you need to map URLs to methods you should check out http://jersey.java.net/. It can be easily integrated with guice using com.sun.jersey.guice.spi.container.servlet.GuiceContainer.
