Demo
1. Create a Constroller Based on the package path (com. mvc. rest) configured in the spring-servlet.xml

[Java]

1. Package com. mvc. rest;
2. Import javax. servlet. http. HttpServletRequest;
3. Import javax. servlet. http. HttpServletResponse;
4. Import org. springframework. stereotype. Controller;
5. Import org. springframework. ui. ModelMap;
6. Import org. springframework. web. bind. annotation. PathVariable;
7. Import org. springframework. web. bind. annotation. RequestMapping;
8. Import org. springframework. web. bind. annotation. RequestMethod;
9. Import org. springframework. web. servlet. ModelAndView;
10. @ Controller
11. Public class RestConstroller {
12. Public RestConstroller (){}
13. @ RequestMapping (value = "/login/{user}", method = RequestMethod. GET)
14. Public ModelAndView myMethod (HttpServletRequest request, HttpServletResponse response,
15. @ PathVariable ("user") String user, ModelMap modelMap) throws Exception {
16. "LoginUser", user );
17. Return new ModelAndView ("/login/hello", modelMap );
19. @ RequestMapping (value = "/welcome", method = RequestMethod. GET)
20. Public String registPost (){
21. Return "/welcome ";

Welcome. jsp: The hello. jsp code is as follows:

[Html]

1. <% @ Page language = "java" import = "java. util. *" pageEncoding = "UTF-8" %>
2. <%
3. Path = request. getContextPath ();
4. BasePath = request. getScheme () + ": //" + request. getServerName () + ":" + request. getServerPort () + path + "/";
5. >
6. >
7. <Html>
8. <Head>
9. <Base href = "<% = basePath %>">
10. <Title> My JSP 'hello. jsp 'starting page </title>
11. <Meta http-equiv = "pragma" content = "no-cache">
12. <Meta http-equiv = "cache-control" content = "no-cache">
13. </Head>
14. <Body>
15. <% = Request. getAttribute ("loginUser") %>. The current time is <% = new Date () %>
16. </Body>
17. </Html>
