Help resolve URL Pattern Issue in Spring

Need assistance from developer calling the URL, http://localhost:8080/[war file]/api/vase/123 with the below configurations. I get the error "Request method 'DELETE' not supported" on the server and "405 Method not allowed" on the client. It only works if RequestMapping in class is @RequestMapping(value="/api", method = [login to view URL]). "/api/vase/123" does not work. An expert should be able to quickly resolve this issue live with me on chat. 1) [login to view URL] <web-app xmlns:xsi="[login to view URL]" xmlns="[login to view URL]" xsi:schemaLocation="[login to view URL] [login to view URL]" id="WebApp_ID" version="3.0"> .... <servlet> <servlet-name>abc</servlet-name> <servlet-class>[login to view URL]</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/[login to view URL]</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>abc</servlet-name> <url-pattern>/api/*</url-pattern> <url-pattern>*.do</url-pattern> </servlet-mapping> .. </web-app> 2) Controller class @Controller public class VaseDelete { @RequestMapping(value="/api/vase/{idx}", method = [login to view URL]) public @ResponseBody void deleteFile(@PathVariable("idx") String uuid, HttpServletResponse response, HttpServletRequest request) { try{ [login to view URL]("text/plain"); [login to view URL]().write("200"); }catch(Throwable th){ } } }
