Spring Boot and Java 16 Records

Did you fix the error and is it working now correctly?

Nice article, Ashish!

It is interesting how different Java decompilers reconstruct the code. In your example javap produced a class that just extends java.lang.Record as if it is a good old Java 1.5 code.

But for example this Java decompiler reconstructs code already with a record keyword.

How to use it in JPA, it requires noArg constructor

One of the features I like about Scala is the one line entity declaration. I'm working on a project with Java and I miss the one line declaration. Sure, I can use Intellij to generate boilerplate code but I personally do not feel it the same.

With regards to your code, is there any reason you prefer straight sql statements than using a ORM? Hibernate maybe?. I know performance would be one but I'm interested to know in alternatives.

Would you recommend java 16 for a project that would take 3 years to develop given that by that time code most likely be fully supported.

Good post btw.

Thanks.
