Spring-Boot@requestmapping和@pathvariable与正则表达式匹配

Question

@ResponseBody
@RequestMapping(method = RequestMethod.GET, value = "/webjars-locator/{webjar}/{partialPath:.+}")
public ResponseEntity<ClassPathResource> locateWebjarAsset(@PathVariable String webjar, @PathVariable String partialPath)
{

http://localhost/webjars-locator/angular-bootstrap-datetimepicker/datetimepicker.js

http://localhost/webjars-locator/datatables-plugins/integration/bootstrap/3/dataTables.bootstrap.css

最根本的区别只是路径中应该由正则表达式（“.+”）处理的组件的数量，但当该部分有斜杠时似乎不起作用。

如果有帮助,请在日志中提供以下内容：

2015-03-03 23:03:53.588信息15324---[main]s.w.s.m.m.a.RequestMappingHandlerMapping：将“{[/webjars-locator/{webjar}/{partialPath:.+}]，Methods=[GET]，Params=[]，Headers=[]，Consumes=[]，Produces=[]，Custom=[]}”映射到公共org.springframework.http.responseEntity app.controllers.WebjarsLocatorController.LocateWebjarAsset（

Spring-Boot中是否有某种类型的隐藏设置来启用RequestMappings上的正则表达式模式匹配？

Answer 1

文档中的原始代码没有为额外的斜杠准备，对不起！

请尝试以下代码：

@ResponseBody
@RequestMapping(value="/webjarslocator/{webjar}/**", method=RequestMethod.GET)
public ResponseEntity<Resource> locateWebjarAsset(@PathVariable String webjar, 
        WebRequest request) {
    try {
        String mvcPrefix = "/webjarslocator/" + webjar + "/";
        String mvcPath = (String) request.getAttribute(
                HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE, RequestAttributes.SCOPE_REQUEST);
        String fullPath = assetLocator.getFullPath(webjar, 
                mvcPath.substring(mvcPrefix.length()));
        ClassPathResource res = new ClassPathResource(fullPath);
        long lastModified = res.lastModified();
        if ((lastModified > 0) && request.checkNotModified(lastModified)) {
            return null;
        }
        return new ResponseEntity<Resource>(res, HttpStatus.OK);
    } catch (Exception e) {
        return new ResponseEntity<>(HttpStatus.NOT_FOUND);
    }
}

我还将很快提供webjar文档的更新。
