Question

在Java-Jersey中，可以接收资源的动态路径，例如

本地主机：8080 / web服务/这个/是/我的/动态/路径

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

打印出：这/是/ my / dynamic / path

问题：如何在Spring MVC中执行此操作？

对于路径中的多个项目，您可以访问动态路径值，如下所示：

@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;
}

如果您事先知道许多级别的路径变量，您可以将它们明确地编码为

@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;
}

如果要查看浏览器中返回的String，则还需要声明方法@ResponseBody（因此返回的String是响应的内容）：

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