[英]My spring-boot app gives the following error “org.thymeleaf.exceptions.TemplateInputException:”
我创建了一个从start.spring.io下载的演示spring-boot应用程序
当我构建Maven应用并运行它时，出现以下错误：

这是结构的图像
您使用Thymeleaf，它可以解析模板索引或主页。 Thymeleaf的TemplateResolver负责加载HTML标记。 默认情况下，它将模板名称（例如home）转换为资源名称（例如classpath:/templates/home.html或WEB-INF/templates/home.html 。
因此，改为home.jsp尝试home.html 。 希望能解决您的问题。
@RequestMapping(value="/",method = RequestMethod.GET)
public ModelAndView homePage() {
ModelAndView modelAndView = new ModelAndView("home");
modelAndView .addObject("appName",appName);
return modelAndView;
}
要么
@RequestMapping(value= {"/","/index"})
public ModelAndView mainPage(Model map) {
map.addAttribute("appName",appName);
return new ModelAndView("home");
}
使用URL调用它：
本地主机：8080 /或本地主机：8080 / index
