• Spring MVC Flow, Concepts, and Implementation Steps
• Understand and use:
  • Model Attributes
  • ModelAndView
  • Model Map
  • Request Parameters
• Spring MVC Hibernate Integration (Without Spring Boot):
  • Layers: Controller, Service, DAO, Entity, DB
  • Task: List Restaurants
• Identify the efforts of extensive configuration.
• Solution to reduce configuration efforts:
  • Use Spring Boot for MVC-based web apps (monolithic).
• Project Technology: MVC Flow with concepts and steps.

1. Integration of Spring MVC with Hibernate

(Refer to flow diagram, code, and steps)

1.1 Spring MVC Flow Diagram

• Describes the request-response lifecycle in a Spring MVC application (as detailed in the "Spring MVC Flow.txt" document).
  • Client Request → DispatcherServlet → Handler Mapping → Controller → Model and View → View Resolution → View Rendering → Response.

1.2 Detailed Controller-Service-DAO-Entities-DB Diagram

• Illustrates the interaction between:
  • Controller: Handles HTTP requests and coordinates with the Service layer.
  • Service: Contains business logic and interacts with the DAO layer.
  • DAO: Manages database operations using Hibernate.
  • Entities: Java classes mapped to database tables.
  • DB: The underlying database.

2. What Happens Internally When Deploying a Spring MVC Hibernate-Based Web App on a Web Server?

2.1 Web Container (WC) Starts the Lifecycle of DispatcherServlet (D.S)

• The web server initializes the DispatcherServlet, which acts as the front controller.
