How does understanding request flow help with debugging?

It helps identify where errors occur by tracing the request through each layer, making it easier to find and fix problems.

What role do services play in the Spring Boot request flow?

Services contain business logic and process data between controllers and repositories, keeping code organized and reusable.

In Spring Boot, which component directly receives the HTTP request from the client?

A Controller

B Service

C Repository

D Entity

Controllers map HTTP requests to methods that handle them.

Why should you understand the request flow in Spring Boot?

A To write HTML code

B To improve debugging and application design

C To manage database connections manually

D To avoid using controllers

Understanding request flow helps with debugging and designing better apps.

What is the main role of the service layer in Spring Boot's request flow?

A Handle HTTP requests

B Store data in the database

C Process business logic

D Render HTML pages

Services process business logic between controllers and repositories.

If a request fails, understanding the request flow helps you to:

A Ignore the error

B Change the browser settings

C Restart the server only

D Find where the error happened

Tracing the request flow helps locate errors quickly.

Which layer in Spring Boot typically interacts with the database?

A Repository

B Controller

C Service

D View

Repositories handle database operations.

Explain the path a user request takes in a Spring Boot application from the moment it arrives until a response is sent.
