为Servlet添加支持REST式URL：ServletREST

为Servlet添加支持REST式URL: 不改变习惯，仅仅在servlet内部完成doGet, doPost,doDelete,doPut等方法即可映射到较为复杂的REST URL
eg:
/book/head first java/ 对应的URL表达式为: /book/*/ /book/head first java/chapter/1 对应的URL表达式为: /book/*/chapter/*
您所要做的： 仅仅需要在web.xml中配置一个filter 仅仅需要在集成HttpServlet添加一个注解(eg:@RestSupport("/book/*/chapter/*"))
下面附加一个使用示范:
@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 ... } }
