Spring不显示网页并且找不到资源

Question

我使用Spring 框架和Thymeleaf 编写了简单的Java 应用程序。在我的 IDE 上，它工作得很好，但是当我制作 JAR 工件并将其导出到我的 linux 服务器时，它正在启动，但我收到了这个错误：

还有我的application.properties 内容：

spring.thymeleaf.check-template-location=true
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html
spring.thymeleaf.cache=false

这里也是我Controller的一部分：

    @GetMapping("/")
    public String loginForm(Model model)
    {
        model.addAttribute("authentication", new Authentication());
        return "login";
    }

有什么想法可以解决吗？ 此外，我仅限于 .jar 文件，因为它必须在 Zebra FX9600 上运行
