解决方案

公共类 CsvFileUploadInterceptor 扩展 FileUploadInterceptor {

private static final long serialVersionUID = 1L;

private static Logger log = Logger.getLogger(CsvFileUploadInterceptor.class);

@Override
protected String getTextMessage(Object action, String messageKey, String[] args) {
    String actionName = action.getClass().getName();
    if (actionName.endsWith(WebAppConst.CSV_UPLOAD_ACTION)) {
        if (messageKey.equals(WebAppConst.STRUTS_MESSAGES_ERROR_FILE_TOO_LARGE)) {
            messageKey = WebAppConst.CSV_UPLOAD_ERROR_FILE_TOO_LARGE;
        } else if (messageKey.equals(WebAppConst.STRUTS_MESSAGES_ERROR_CONTENT_TYPE_NOT_ALLOWED)) {
            messageKey = WebAppConst.CSV_UPLOAD_ERROR_CONTENT_TYPE_NOT_ALLOWED;
        }
    }
    return super.getTextMessage(actionName, messageKey, args);

}

}
