2.6 Summary

• Spring offers a powerful web framework called Spring MVC that can be used to develop the web frontend for a Spring application.
• Spring MVC is annotation-based, enabling the declaration of request-handling methods with annotations such as @RequestMapping, @GetMapping, and @PostMapping.
• Most request-handling methods conclude by returning the logical name of a view, such as a Thymeleaf template, to which the request (along with any model data) is forwarded.
• Spring MVC supports validation through the JavaBean Validation API and implementations of the Validation API such as Hibernate Validator.
• View controllers can be registered with addViewController in a WebMvcConfigurer class to handle HTTP GET requests for which no model data or processing is required.
• In addition to Thymeleaf, Spring supports a variety of view options, including FreeMarker, Groovy templates, and Mustache.
