IoC and Dependency Injection: How Spring Boot Manages Class Dependencies

In large software projects, manually creating objects for every class becomes complex and difficult to manage. Inversion of Control (IoC) is a design principle where a framework or container takes responsibility for managing dependencies instead of the programmer. Dependency Injection (DI) is the practical implementation of the IoC principle. In Spring Boot, the @Component annotation marks subclasses, while @Autowired is used to inject and utilize them automatically. Together, IoC and DI simplify workflows and save development time in large-scale applications.
