【问题描述】：
我有一个使用 Thymeleaf 渲染模板的 springBoot 应用程序。当我从 Eclipse 运行应用程序时，一切正常。但是，当我尝试构建 jar 并运行它时，一个模板拒绝加载，但出现以下异常：
异常处理模板“/XXX/form/importConfiguration”：错误 解析模板“/XXX/form/importConfiguration”，模板可能不会 任何已配置的模板存在或可能无法访问 解析器
控制器代码很简单：
@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可以正常运行。任何人都可以帮我解决这个问题吗？

更新：
控制器本身似乎有问题。当我尝试在控制器中返回另一个模板的名称时，它在另一个控制器中加载得很好，我得到了同样的异常。因此，出于某种原因，Thymeleaf 似乎无法从该控制器加载模板。
【问题讨论】：
-
“XXX”目录下是否有“form”文件夹？将包类型更改为 war 并再次构建。然后尝试在 tomcat 独立安装中运行它。
-
是的，“form”文件夹确实存在。我认为更改包装需要对代码进行重大更改，目前我还不愿意这样做
-
可以分享一下 pom.xml 吗？
-
您不需要做任何代码更改。只需在 pom.xml 中的
1.7 下添加war -
我试过了，但是没有用。我在网上的几个地方读到，我的主类需要扩展 SpringBootServletInitializer 才能在 tomcat 下部署，这需要比我愿意做的更多的更改。
