2. Advanced Spring Boot Configurations

2.1. Optimizing Spring Boot with Lazy Initialization

Spring Boot's support for lazy initialization is a game-changer. By deferring bean creation until required, significant startup time reductions are achievable, especially in large codebases. This feature, available from Spring Boot 2.2, can be activated using the spring.main.lazy-initialization=true property in application.properties. While this approach can speed up startup, it may slow down the handling of the first request and obscure certain startup errors.
