Spring Boot-Thymeleaf-新项目无法正常工作

如何解决Spring Boot-Thymeleaf-新项目无法正常工作

我需要帮助才能使用Spring Boot启动新项目。

我使用了spring工具套件4“ spring starter project”。

我正确地遵循了指南的所有步骤，但是一旦我运行localhost：8080，它告诉我无法访问该站点。在问题部分，我有0个问题和警告。

解决方法

您在home.html中的名称空间不完整http://www.w3.org/1999/xhtml。

<html lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">

我试图在本地创建一个项目，并且遇到了同样的问题。

我通过在模板文件夹下添加一个html文件来解决此问题。基本上，这是您的thymeleaf模板所在的位置。添加屏幕截图。

如果要从/home访问主页，请将其添加到属性文件中

server.servlet.context-path=/home
