ServletREST為Servlet添加支持REST式URL

為Servlet添加支持REST式URL: 不改變習(xí)慣，僅僅在servlet內(nèi)部完成doGet, doPost,doDelete,doPut等方法即可映射到較為復(fù)雜的REST URL

eg:

/book/head first java/
對(duì)應(yīng)的URL表達(dá)式為:
/book/*/

/book/head first java/chapter/1
對(duì)應(yīng)的URL表達(dá)式為:
/book/*/chapter/*

您所要做的： 僅僅需要在web.xml中配置一個(gè)filter 僅僅需要在集成HttpServlet添加一個(gè)注解(eg:@RestSupport("/book/*/chapter/*"))

下面附加一個(gè)使用示范:

@RestSupport("/book/*/chapter/*")
public class ChapterServlet extends HttpServlet {
        private static final long serialVersionUID = -1534235656L;

        protected void doGet(HttpServletRequest request,
                        HttpServletResponse response) throws ServletException, IOException {
                // code here ...
        }

        protected void doPost(HttpServletRequest request,
                        HttpServletResponse response) throws ServletException, IOException {
                // code here ...
        }

        protected void doPut(HttpServletRequest request,
                        HttpServletResponse response) throws ServletException, IOException {
                // code here ...
        }

        protected void doDelete(HttpServletRequest request,
                        HttpServletResponse response) throws ServletException, IOException {
                // code here ...
        }
}
