使用Thymeleaf加載Spring Boot模板時出錯

Question

我有一個使用Thymeleaf渲染模板的springBoot應用程序。 當我從Eclipse運行應用程序時，所有功能都可以正常運行。 但是，當我嘗試構建jar並運行它時，一個模板拒絕加載，但出現以下異常：

異常處理模板“ / XXX / form / importConfiguration”：解決模板“ / XXX / form / importConfiguration”時出錯，模板可能不存在，或者任何已配置的模板解析器都無法訪問該模板

控制器代碼非常簡單：

@Controller
public class ImportConfigurationsController extends BaseController
{
   private static final Logger log = LoggerFactory.getLogger(ImportConfigurationsController.class);

   private static final String PATH_IMPORT_CONFIG = "/XXX/importConfigurations";
   private static final String PATH_INIT_IMPORT_CONFIG = "/XXX/initLoadingXMLConfiguration";
   private static final String PATH_IMPORT_CONFIG_FROM_XML = "/XXX/importConfigurationFromXML";
   private static final String TEMPLATE_IMPORT_CONFIG = "/XXX/form/importConfiguration";

   /**
    * Loads the import configuration page
    * 
    * @param model
    * @return
    * @throws Exception
    */
   @GetMapping(PATH_IMPORT_CONFIG)
   public String importConfiguration(Model model) throws Exception
   {
      log.trace("Enter Method importConfiguration. Params: {}", model);

      log.trace("Return Method importConfiguration.");
      return TEMPLATE_IMPORT_CONFIG;
   }

我檢查了jar文件，並且html文件確實存在。 此外，除此模板以外的所有其他模板都可以正常運行。 有人可以幫我嗎？

更新：

控制器本身似乎有問題。 當我嘗試在控制器中返回另一個模板的名稱（該模板在另一個控制器中加載得很好）時，我遇到了相同的異常。 因此由於某些原因，Thymeleaf似乎無法從該控制器加載模板。

Answer 1

很抱歉浪費大家的時間。 事實證明，像往常一樣，有一個愚蠢的簡單原因使我遇到了這個問題。 在創建新的控制器時，似乎我們監督了模板路徑中的前導“ /”。 因此，它的路徑不是“ XXX / path / to / file”，而是“ /XXX/path/to.file”。
我添加此代碼是為了讓其他可能遇到此問題的人受益。

在事后思考中，我認為應該在某個地方突出顯示該錯誤消息，因為該錯誤消息遠非描述性的。 前導“ /”不應停止加載模板，如果這樣，則該錯誤至少應指出發生了什么問題。
