thymeleaf各种问题，标签没用?网页404？

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>
 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
<dependency>
            <groupId>net.sourceforge.nekohtml</groupId>
            <artifactId>nekohtml</artifactId>
        </dependency>
 <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
    <dependency>
            <groupId>org.thymeleaf</groupId>
            <artifactId>thymeleaf</artifactId>
            <version>3.0.9.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

<?xml version="1.0" encoding="UTF-8"?>

            </resource>
        </resources>
    </build>

</project>

　　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。
