首先html的网页
<!DOCTYPE html>
//注意这个xmlns后面一定是https，我的就是没加s导致无法识别msg这种变量
<html lang="en" xmlns:th="https://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Thymeleaf 语法</title>
</head>
<body>
<p th:text="${msg}"></p>
</body>
</html>
其次，html文件基本都说是放在templates文件夹下，然后用application.properties写一下解析器（前4行应该都必要写上去）
spring.resources.static-locations=classpath:/templates/
spring.thymeleaf.cache=false
spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.suffix=.html
spring.thymeleaf.encoding=UTF-8
最重要的导入的包！！！！我可能这一天就死在导包上了
<properties>
<java.version>1.8</java.version>
<thymeleaf-layout-dialect.version>2.1.1</thymeleaf-layout-dialect.version>
<project.build.sorceEncoding>UTF-8</project.build.sorceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties>
//下面是我觉得必须要用到的包，反正我少一个就起不来，百度上的也没总结，我就自己写了
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring5</artifactId>
<version>3.0.11.RELEASE</version>
</dependency>

当然web的包是必要的这边也再做下累述吧。嫌自己看包麻烦想复制粘贴配置的请复制下面的

最后的话，controller层基本应该没什么问题的，后台传个值到前台。这里也不多做累述。
