Caching in Spring Boot with Simple Example

Caching helps us to make our Spring Boot applications faster to respond, more scalable, and less resource intensive. It's incredibly easy to implement, with just two simple annotations: @EnableCaching and @Cacheable. In this video, we explain what Caching is, why we want to do it, and then we demonstrate it with a simple example in source code, complete with a debugger walkthrough.

Done thanks. Cache usually at the service layer. @cacheable(“name”) method annotation uses method Paramus as key and returned object as value. Careful when debugging, the flow will stop at the cached method doesn’t actually call repository.
TODO:- what is the name param given to the cacheable annotation

Very helpful, thank you! What is the cache default TTL and how to change it?

Hi @Brandan Jones, very nicely explained. I have one query:
Say as i have an GET request in which i am not passing any queryparams. Now that controller is calling a service method and in that service method i am calling findAll method of Hibernate JPA.
Since in the above scenario, i do not have any key passing from controller to service layer, how caching will work in this scenario?

This is a great video and very easy to understand! Though I have one question. How are the cache contents updated? I understand that CachePut does this, however it also invokes the DAO method every single time, unlike Cacheable. What happens if the we introduce a new plant to the database--this plant won't show up if we search for it because Cacheable does not update the cache contents, correct?
