Most preferred would be Spring Data-JPA as it is the most recent out of the ones mentioned ones above.
That being said, it prevents lot of boilerplate code and supports Query methods which are quite convenient.

I would like to add something more recent which is not much in picture currently but it should be in near future.

Going reactive with Spring Data

Have you had any experience with this framework?



I have good amount of experience working with Spring Boot 1.5 / Spring framework 4 and Swagger, but unfortunately didn't get chance to start with spring 5/ spring boot 2 specific project.


Caused by: java.lang.NoClassDefFoundError: org/springframework/web/servlet/mvc/method/annotation/RequestMappingHandlerAdapter



Have you tried deleting RequestMappingHandlerAdapter related folders from your local Maven/Gradle repository and trying to re-build project?

Hi Pete,

I would like you to take a look at this, it might have something useful.

"pointsEarned cannot be resolved to a variable"
"pointsMax cannot be resolved to a variable"

I have clearly initialized these on lines 29 band 41 so I am not sure what the deal is



You've declared those variables inside for loop, and trying to return them outside for loop. Those variables have gone out of scope post for loop block.
Please declare and initialise them at the start of methods to keep them in scope.

Please delete the .metadata folder in your workspace after closing eclipse, and then try again.


Note: It is going to reset your workspace specific settings.

Look for the Java® Virtual Machine Specification (I think) (=JVMS), not the Java® Language Specification.



Hi Campbell,
The link I provided has links to both VM specs as well as Lang Specs. 

Thanks for pointing that out, hope I haven't missed anything.

Did you try changing the run configuration to have JDK/JRE 1.8 as a runtime for execution of your project ?

Have you inadvertently applied a filter to the window?



I have not.  I double check the preferences and then I re-set to default but still I can't debug.

I thought it is because I did not put breakpoints so I put a few of them around transaction.commit etc but it is still not debugging.

I noticed the step-over, step-in buttons are all greyed out....is there anything I can do to make them not grey out ?



I can see the issue there, I can see that you have enabled 'Skip all breakpoints' (Button with a dot and diagonal strikethrough) there. Please disable it and it should work fine.

Tim Holloway wrote:My go-to book isn't very recent. It's the aPress Pro JPA 2 book. It has been helpful for even the most complex of projects using things like the query builder, native queries, all sorts of joins and fetches and so forth. It covers the fundamentals very well and as far as I know, nothing radical enough has happened to JPA since it came out that I actually require something newer. Excepting of course, the product-specific on-line manuals at places like hibernate.org. Those are frequently more up-to-date than anything you can buy from a bookseller.



Thanks for your input Tim, I will definitely take a look at the book.
