ajax - TemplateInputException : Error resolving template ****, 模板可能不存在

Question

我将 SpringBoot 与 mySql 数据库一起使用。

我正在尝试通过团队表过滤搜索。最初这张表是一个百里香叶表(请参阅我的相关 SO 问题)，但在用尽互联网上的所有可用资源后，没有成功，我决定以不同的方式实现搜索。

我找到了一个非常有用的网站，其中有一个实用的、相关的示例，说明了我想要实现的内容。

http://javasampleapproach.com/frontend/bootstrap/bootstrap-filter-table-jquery-springboot-restapi

我有一个很好的工作示例，但是当我将它实现到我的项目中时，我遇到了一些发人深省的错误，因为我是一个完全的菜鸟，我正在寻求 stackoverflow 用户的慷慨帮助。

我也尝试过搜索堆栈溢出的解决方案，但没有成功。

Error resolving template "index", template might not exist or might not be accessible by any of the configured Template Resolvers

Thymeleaf cannot detect templates inside spring-boot project

当我进入相关网页时，我立即收到一个错误对话框，请参阅下面的控制台错误，您还可以看到该表根本没有被填充，实际上是空的:



!Console Error ] 2

我的服务器端代码错误:

我的项目设置:

Answer 1

需要更多关于如何设置项目的详细信息。

你的 html 在哪里。它在/resources/templates 下吗？

你失踪了 <html xmlns:th="http://www.thymeleaf.org">在你的 html 上。

尝试注释掉您的 jQuery Ajax 调用，看看您的初始 html 是否正确加载。

你的 Controller 休息 Controller @RestController 是一个方便的注释，它只是添加了 @Controller 和 @ResponseBody 吗？

检查这些，它应该可以解决您的问题。
