篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Thymeleaf 异常:Exception processing template "index": An error happened during template pars相关的知识,希望对你有一定的参考价值。
Spring Boot 项目,在 Spring Tool Suite 4, Version: 4.4.0.RELEASE 运行没有问题,将项目中的静态资源和页面复制到 IDEA 的项目中,除了 IDE 不同,其他基本相同。
运行 IDEA 中的项目,然后访问,出现异常:
Exception processing template "index": An error happened during template parsing (template: "class path resource [templates/index.html]")
具体异常:

起初是直接运行项目,即 Shift + F10:
后来重新编译项目,再访问,就没有出现异常:
