从 spring 引导向后迁移到 spring 内核

Question

I know that spring boot is a wrapper for spring framework, so is it possible to achieve better running time performance for a application by migrating backwards from spring boot to spring core? If so, what changes need to be made? Is just changing the configuration files and modifying some annotations enough?

Answer 1

Spring Boot is just a helper to make the configuration and setup of a Spring application a bit easier by using good default behaviours. It adds some functionality for starting the application (configuration), but it doesn't add (that much) behaviour for the "normal" runtime.

So removing Spring Boot will typically not give you a significant improvement in runtime performance (in terms of speed).

If your application use a database, and this is somehow related to your performance issue, then you maybe should optimize this. (Database Index, Better/Less queries, pure SQL instead of JPA, caches, ....)
