首先html的網頁
<!DOCTYPE html>
//注意這個xmlns后面一定是https，我的就是沒加s導致無法識別msg這種變量
<html lang="en" xmlns:th="https://www.thymeleaf.org">
<head>
<meta charset="UTF-8">
<title>Thymeleaf 語法</title>
</head>
<body>
<p th:text="${msg}"></p>
</body>
</html>
其次，html文件基本都說是放在templates文件夾下，然后用application.properties寫一下解析器（前4行應該都必要寫上去）
spring.resources.static-locations=classpath:/templates/
spring.thymeleaf.cache=false
spring.thymeleaf.mode=LEGACYHTML5
spring.thymeleaf.suffix=.html
spring.thymeleaf.encoding=UTF-8
最重要的導入的包！！！！我可能這一天就死在導包上了
<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>
//下面是我覺得必須要用到的包，反正我少一個就起不來，百度上的也沒總結，我就自己寫了
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring5</artifactId>
<version>3.0.11.RELEASE</version>

當然web的包是必要的這邊也再做下累述吧。嫌自己看包麻煩想復制粘貼配置的請復制下面的

最后的話，controller層基本應該沒什么問題的，后台傳個值到前台。這里也不多做累述。
