我有一个基于RESTful spring的端点,可以将存储在db中的资源存储到javascript编辑器中.相关部分归结为:

@RestController
@RequestMapping(ThemeEndpoint.ENDPOINT_NAME)
public class ThemeEndpoint {

public static final String ENDPOINT_NAME = "/themes"; 

    @RequestMapping(value="/{id}/css/{assetName:.*}", method=RequestMethod.GET)
    public Asset getCssItem(
        @PathVariable("id") ThemeId id, 
        @PathVariable("assetName") String name) {
    CssThemeAsset themeAsset = themeService.getCssAsset(
                id, ThemeAssetId.fromString(name));
    Asset asset = new Asset();
    asset.name = themeAsset.getName();
    asset.text = themeAsset.getContent();
    return asset;
}

对于像这样的网址,这可以正常工作

http://localhost:8080/app-url/rest/themes/ac18a080-a2f1-11e3-84f4-600308a0bd14/css/main.less

但是一旦我将扩展名更改为,就会失败.css.

经过一些调试后,我非常确定如果我使用的是url,请求甚至都没有映射

http://localhost:8080/app-url/rest/themes/ac18a080-a2f1-11e3-84f4-600308a0bd14/css/main.css

对于高日志级别,我可以看到映射是由spring捕获的:

org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping 
    - Mapped "{[/themes/{id}/css/{assetName:.*}],methods=[GET],params=[],headers=[],
                consumes=[],produces=[application/json],custom=[]}" 
      onto public xxx.endpoint.ThemeEndpoint$Asset
          xxx.endpoint.ThemeEndpoint.getCssItem(
              net.lacho.svc.themes.api.ThemeId,java.lang.String)   

并且使用非.css扩展名调用控制器:

Found 1 matching mapping(s) for [/themes/ac18a080-a2f1-11e3-84f4-600308a0bd14/css/main.less]
  : [{[/themes/{id}/css/{assetName:.*}],methods=[GET],params=[],headers=[],
        consumes=[],produces=[application/json],custom=[]}]

但是只要我使用.css作为扩展名 - bang:

Looking up …

我发现了Spring MVC的一个非常奇怪的行为.

我有控制器方法:

@RequestMapping (value = "/delete/{id:.*}", method = RequestMethod.DELETE)
public ResponseEntity<Response> delete(@PathVariable (value = "id") final String id) {
    HttpStatus httpStatus = HttpStatus.OK;
    final Response responseState = new Response( ResponseConstants.STATUS_SUCCESS );
    try {
        POJO pojo = mediaFileDao.findById( id );
        if (pojo != null) {
            delete(pojo);
        } else {
            httpStatus = HttpStatus.NOT_FOUND;
            responseState.setError( "NOT_FOUND" );
        }
    } catch (Exception e) {
        httpStatus = HttpStatus.INTERNAL_SERVER_ERROR;
        responseState.setError( e.getMessage() );
    }
    return new ResponseEntity<>( responseState, httpStatus );
}

所以,问题是当id包含点(例如"my_file.wav")时,Spring在任何情况下都会返回HTTP 406,但是如果id不包含点,则Spring会按照我的方式返回responseState(作为json).我尝试以不同的方式修复它(添加@ResponseBody,更改jackson版本,将Spring降级到4.0)但没有任何结果.

谁能帮我？

更新我为Spring …
