Spring Boot+thymeleaf+Layui 表格渲染出错问题

前言

我在使用Layui做前端表格的时候遇到两个问题，第二个问题其实是我自己解决第一个问题不注意带来的问题，也是这第二个问题困扰了我很久，所以记录一下。

一、Layui [[]] 使用的问题

最开始我按照Layui官网的代码写好了一个html页面

然后访问报错如下

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/customer_list.html]")

这个问题我在网上搜到了，是因为[[]]使用的问题

这个问题有两个解决办法
