说白了就是找不到相应的类

POM：文件引错了。

<groupId>org.thymeleaf</groupId>

<artifactId>thymeleaf</artifactId>

<version>3.0.6.RELEASE</version>

</dependency>

应该引：

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-thymeleaf</artifactId>

</dependency>

这里之所以没有version 是因为

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>2.0.1.RELEASE</version>

</parent>

这里有依赖。。

小小记录一下，每天进步一小步
