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
