A zero-write Java Web framework--processing of requests

Approximate idea

1. Inherit HttpServlet, implement Dispatcherservlet, intercept all requests;
2. Dispatchservlet rewrite the init () method, which is responsible for initializing the framework;
3. Rewrite the service () method to get HttpServletRequest, httpservletresponse;
4. Through the HttpServletRequest, the HttpServletResponse, obtains the request path, the request parameter, carries on the request processing, and does the forwarding or redirects;
