如何獲取作為 Spring MVC 中剩余路徑的路徑變量?

[英]How to get a path variable that is the remainder of the path in Spring MVC?

我怎樣才能讓我的最后一個路徑變量成為剩余的路徑? 我有這樣的事情,但沒有受到打擊:

@RequestMapping(value = "{storageId}/{repositoryId}/{path}/**",
                method = RequestMethod.PUT)
@RequestMapping(value = "{storageId}/{repositoryId}/{path}/**", method = RequestMethod.PUT)
public ResponseEntity upload(@PathVariable(name = "storageId") String storageId,
                             @PathVariable(name = "repositoryId") String repositoryId,
                             @PathVariable(name = "path") String path,
                             MultipartFile multipartFile)
        throws ...
{
   ...
}

在澤西島,我可以像這樣輕松做到:

@Path("{storageId}/{repositoryId}/{path:.*}")

...但我必須將一些代碼遷移到 Spring MVC。

問題是,如果我的網址是:

http://localhost:48080/storages/storage0/snapshots/org/foo/bar/metadata/metadata-foo/3.1-SNAPSHOT/metadata-foo-3.1-20161017.182007-1.jar

我的path被截斷為:

metadata/metadata-foo/3.1-SNAPSHOT/metadata-foo-3.1-20161017.182007-1.jar

這顯然是不正確的,因為它應該是:

org/foo/bar/metadata/metadata-foo/3.1-SNAPSHOT/metadata-foo-3.1-20161017.182007-1.jar

任何的建議都受歡迎!

 @RequestMapping(value = "{storageId}/{repositoryId}/{path}/**",
                 method = RequestMethod.PUT)
 public ResponseEntity upload(@PathVariable(name = "storageId") String storageId,
                              @PathVariable(name = "repositoryId") String repositoryId,MultipartFile multipartFile,HttpServletRequest request)
            throws ...
    {
        String restOfTheUrl = (String) request.getAttribute(
        HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
    }

使用 Spring 5 中開始出現的新(ish)匹配算法很容易。您只需使用{*foo}作為路徑模式。

@RequestMapping(value = "{storageId}/{repositoryId}/{path}/{*rest}",
                method = RequestMethod.PUT)
public ResponseEntity upload(@PathVariable(name = "storageId") String storageId,
                             @PathVariable(name = "repositoryId") String repositoryId,
                             @PathVariable(name = "path") String path,
                             @PathVariable(name = "rest") String rest,
                             MultipartFile multipartFile)
        throws ...
{
   ...
}

這在 Webflux 中默認有效。 對於 MVC,您必須使用spring.mvc.pathmatch.matching-strategy=path_pattern_parser打開PathPattern匹配器。 我知道這將是 Spring Boot 2.6 中的默認設置。
