Some of the common drawbacks of Spring Boot to keep in mind is its complexities. While working with Spring Boot, converting legacy to a full-fledged Spring Boot app could take up your time. Secondly, Spring Boot’s flexibility with large-scale projects isn’t suitable in the long run. As a developer, if you wish to choose Spring Boot to create monolithic apps, you will be disappointed. Finally, Spring Boot’s lack of control could multiply dependencies that could result in the execution of massive deployment data.
