使用Thymeleaf加载Spring启动模板时出错

Question

我有一个springBoot应用程序，它使用Thymeleaf渲染模板。当我从Eclipse运行应用程序时，所有这些都可以完美地工作。但是，当我尝试构建并运行jar时，有一个模板拒绝加载，出现以下异常：

异常处理模板“/XXX/form/importConfiguration”：错误解析模板“/XXX/form/importConfiguration”，模板可能不存在或无法由任何已配置的模板解析程序访问

控制器代码非常简单：

@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;
   }

我检查了jar文件，html文件确实存在。此外，除此之外的所有其他模板都正常运行。有人能帮我吗？

编辑：pom.xml

更新：

控制器本身似乎有问题。当我尝试返回控制器中另一个模板的名称时，它在另一个控制器中加载得非常好，我得到了相同的异常。因此，出于某种原因，Thymeleaf似乎无法从该控制器加载模板。

Answer 1

对不起，浪费了大家的时间。和往常一样，我有这个问题的原因非常简单。在创建新控制器时，我们似乎看到模板路径中有一个前导“/”。因此，路径不是“XXX/path/to/file”，而是“/XXX/path/to.file”
我添加此内容是为了让可能遇到此问题的其他人受益事后想一想，我认为应该在某个地方强调这一点，因为错误消息远非描述性的。前导“/”不应停止加载模板，如果是这样，错误至少应给出出错原因的指示。
