SpringBoot integrates FreeMarker and Thymeleaf

Although front-end and back-end separation is now the dominant development approach, it is important to understand the template engine. Although the default template engine for Spring-MVC is JSP, who still uses JSP after 9102 years? The official SpringBoot template engine is Thymeleaf, which also supports FreeMarker.

SpringBoot projects can be generated at start.spring. IO /, or they can be created directly from the IDE.
