Spring - flexible Java framework

Example

Spring's IoC container lets applications dynamically assign object dependencies at runtime rather than during compile time. This is fundamental for applications where configuration changes frequently but does not require recompilation.

Scenario

An e-commerce application where the payment service can be switched between PayPal and Stripe without changing the code.

Example

Enables clean separation of concerns, particularly useful for implementing cross-cutting concerns such as transactions or logging.

Scenario

In a banking app, logging access to sensitive operations or automatically managing transactions without invading business logic code.

Example

Spring simplifies interactions with persistence technologies like JDBC, JPA or Hibernate, reducing boilerplate code significantly.

Scenario

An application uses Spring Data repositories to manage database operations without direct JDBC code, making the code cleaner and more maintainable.

Example

Spring provides programmatic and declarative transaction management which helps in maintaining clean separation of transaction management from business logic.

Scenario

A financial application automatically rolls back a transaction if any step in the sequence of operations fails, ensuring data consistency.

Example

Simplifies building production-ready Spring applications with minimal configuration, focusing on convention over configuration.

Scenario

A microservice for a movie streaming platform can be independently developed, deployed, and scaled using Spring Boot.
