简介
Spring MVC 支持各种模版技术，如 Thymeleaf , FreeMarker , JSP 等。而Thyemeleaf 原型即页面的特性或许更符合 Spring Boot 快速开发的思想而被官方推荐。
Thymeleaf 是适用于 Web 开发的服务端 Java 模版引擎，Thymeleaf 为开发工作流程带来优雅自然的模版，由于其非侵入的特性，可以让页面不管是在静态原型下还是用作模版引擎时都有良好的页面展现。

测试
不兼容
当在使用Thymeleaf，实际上在用 ThymeleafViewResolver，这时mvc 的 InternalResourceViewResolver 不生效，当然我们可以通过配置让它们可以兼容使用。
