NoResourceFoundException：没有静态资源，但它存在于 resources/static

问题描述 投票：0回答：1

我最近一直在练习使用 Thymeleaf 和 Spring Boot 并连接到 MySQL 数据库。但是，我遇到了一些问题。

在我尝试使用 Spring Boot 将数据插入 MySQL 数据库之前（我将数据添加到表中），页面显示正确。但是，尝试添加数据后，页面显示白标错误页面。

这是我得到的错误：

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found. status=404).
No static resource templates/products/create.
org.springframework.web.servdet.resource.NoResourceFoundException: No static resource templates/products/create.

我使用XAMPP管理MySQL，不知道是不是端口问题？

我真的感觉很混乱。

这是我的目录结构：

我试图找出连接名称是否有拼写错误，并且还检查了application.properties文件，但问题没有解决。

错误显示“没有静态资源模板/产品/创建。” 我认为您请求了 http://localhost/products/create。 您映射的 url 是 http://localhost/products 或 http://localhost/products/ 您必须在 http://localhost/products 或 http://localhost/products/ 上请求
