dynamic path to resource in springmvc

Question

In Java-Jersey, it is possible to receive a dynamic path to a resource, e.g.

localhost:8080/webservice/this/is/my/dynamic/path

@GET
@Path("{dynamicpath : .+}")
@Produces(MediaType.APPLICATION_JSON)     
public String get(@PathParam("dynamicpath") String p_dynamicpath) {
     return p_dynamicpath;
} 

prints out: this/is/my/dynamic/path

Question: how to do this in Spring MVC?

Answer 1

For multiple items inside your path you can access the dynamic path values like this:

@RequestMapping(value="/**", method = RequestMethod.GET)
public String get(HttpServletRequest request) throws Exception {
    String dynPath = (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    System.out.println("Dynamic Path: " + dynPath );
    return dynPath;
}

If you know beforehand hoe many levels of path variables you'll have you can code them explicit like

@RequestMapping(value="/{path1}/{path2}/**", method = RequestMethod.GET)
public String get(@PathVariable("path1") String path1,
          @PathVariable("path2") String path2,
          HttpServletRequest request) throws Exception {
    String dynPath = (String) request.getAttribute(HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    System.out.println("Dynamic Path: " + dynPath );
    return dynPath;
}

If you want to see the String returned in your browser, you need to declare the method @ResponseBody as well (so the String you return is the content of your response):

@RequestMapping(value="/**", method = RequestMethod.GET, produces = "text/plain")
@ResponseBody
public String get(HttpServletRequest request) throws Exception {
