Thymeleaf 异常：Exception processing template "index": An error happened during template parsing (template: "class path resource [templates/index.html]")

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：

Java 里的异常(Exception)详解

作为一位初学者, 本屌也没有能力对异常谈得很深入.   只不过Java里关于Exception的东西实在是很多. 所以这篇文章很长就是了.. 一, 什么是java里的异常 由于java是c\c++ 发展而来的,  首先我们先看看c语言里的错误. 1.1 c语言里的错误 我们实现1个程序的过程包括,  代码编写, 编译代码成为程序,  执行程序. . 其中大部分常见的语法错误都会被编译代码这样部过滤掉.   但是即使通过了编译. 执行程序这一步可能还是会有错误. 原因很多, 例如常见的除数为0,

JAVA学习--异常Exception

一.异常的体系结构 * java.lang.Throwable  *         |-----Error:错误,程序中不进行处理  *         |-----Exception:异常,要求在编写程序时,就要考虑到对这些异常的处理  *                 |-----编译时异常:在编译期间会出现的异常(执行javac.exe命令时,出现异常) *                 |-----运行时异常:在运行期间出现的异常(执行java.exe命令时,出现异常)  *  *

理解Python语言里的异常(Exception)

Exception is as a sort of structured "super go to".异常是一种结构化的"超级goto". 作为一个数十年如一日地钟爱C语言的程序员(因为C程序员需要记忆的关键字很少,而且可以很惬意地玩内存),对于高级语言如Python里的异常(Exception)一直不甚理解,尤其是其实现机理.但读了<Learning Python>一书中上面这句话(尤其是goto关键字)后,忽然豁然开朗. 如果用C语言编写一个鲁棒性良

浅谈java异常[Exception]

本文转自:focusJ 一． 异常的定义 在<java编程思想>中这样定义 异常:阻止当前方法或作用域继续执行的问题.虽然java中有异常处理机制,但是要明确一点,决不应该用"正常"的态度来看待异常.绝对一点说异常就是某种意义上的错误,就是问题,它可能会导致程序失败.之所以java要提出异常处理机制,就是要告诉开发人员,你的程序出现了不正常的情况,请注意. 记得当初学习java的时候,异常总是搞不太清楚,不知道这个异常是什么意思,为什么会有这个机制?但是随着知识的积累逐渐也
