Spring

Spring Overview

  • Spring is a Model-View-Controller (MVC) framework

  • MVC: a design pattern where software is divided into three distinct categories:

    • Model - Class/data structure-- much can be easily reused between applications

    • View - Frontend rendered content and UIs

    • Controller - Backend data flow management of both Model and View layers

  • A subset of data that is accessible during viewing is model attributes. The addAttribute() method, ModelAndView() function, and @ModelAttribute annotation before a function all define model attributes.

  • Model attributes can be accessed with the ${attributeName} syntax.

  • Attributes can be defined for a particular session or request
