An error happened during template parsing (template: "class path resource [templates/emp/list.html]"

报错信息如下:

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=Internal Server Error, status=500).
An error happened during template parsing (template: "class path resource [templates/emp/list.html]")

网上很多博主都说是因为文件开头加了
https: xmlns:https="http://www.w3.org/1999/xhtml"
和
xmlns:th="http://www.thymeleaf.org"
冲突了

而我认为不以为然

具体的原因就是你在使用thymeleaf模板的时候语法错误，另一种说法加入你跳转到list.html页面的时候出现这个报错，那么证明list.html页面里面有语法错误，请仔细检查

下面我展示一下我的错误：

错误代码:(取值的时候多了一个大括号)

正确代码:

其实有时候你也可以通过控制台得到错误的地方，看以下报错的最后一行
Caused by: org.attoparser.ParseException: Could not parse as expression: “${emp.lastName}}” (template: “emp/list” - line 197, col 17)
错误在197行，17列
