Dependency Injection in Spring Boot allows for loosely coupled components by injecting dependencies at runtime.

• Dependency Injection is a design pattern where objects are passed their dependencies rather than creating them internally.

• In Spring Boot, dependencies are injected using @Autowired annotation.

• By using Dependency Injection, components can be easily swapped out and tested independently.

• Example: @Autowired privat...read more

Profiling in Spring Boot involves analyzing the performance of an application to identify bottlenecks and optimize its efficiency.

• Profiling tools like VisualVM, YourKit, and JProfiler can be used to analyze the performance of Spring Boot applications.

• Profiling helps in identifying memory leaks, CPU usage, and other performance issues in the application.

• By analyzing the profiling results, developers can optimize the cod...read more
