Dropwizard + Katharsis：Preflight（OPTIONS）返回404

我不知道如何配置這兩個庫來正確處理預檢請求（來自Ember.js）。使用下面的過濾器的工作方式與標準Dropwizard /新澤西資源不錯，但什麼都不做的時候卡塔西斯被髮揮出來Dropwizard + Katharsis：Preflight（OPTIONS）返回404

 FilterRegistration.Dynamic filter = environment.servlets().addFilter("CORS", CrossOriginFilter.class); 
     filter.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), false, environment.getApplicationContext().getContextPath() + "*"); 
     filter.setInitParameter(ALLOWED_METHODS_PARAM, "OPTIONS,GET,PUT,POST,DELETE,HEAD"); 
     filter.setInitParameter(ALLOWED_ORIGINS_PARAM, "*"); 
     filter.setInitParameter(ALLOWED_HEADERS_PARAM, "Content-Type," + "X-Requested-With," + "Accept," + "Origin," + "Authorization," + "Access-Control-Request-Method," + "Access-Control-Request-Headers," + "Access-Control-Allow-Origin"); 
     filter.setInitParameter(ALLOW_CREDENTIALS_PARAM, "true"); 
     filter.setInitParameter(ACCESS_CONTROL_ALLOW_ORIGIN_HEADER, "*");

我能找到的人來說，這使用Spring是如何解決的幾個例子，但我似乎無法以適應那些以適應任何一個。

我需要註冊Katharsis的具體內容嗎？
