Cannot resolve MVC view ‘xxx‘

这是在springboot下通过controller访问templates目录下的静态文件（Hello.html)报的错误

原因：缺少thymeleaf依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-thymeleaf</artifactId>
    <version>2.0.4.RELEASE</version>
</dependency>

添加之后并刷新

Hello下的波浪线变成直线说明错误得以解决
