QueryDslSupport does not support Repositories to be declared in different maven modules

[maybeec]

I am facing the following issue.
My setup is

<one of many apps>
 -> declaring code to access a security component
<shared lib "security">
 -> declaring the security component including the declaration of a JPA repository (spring data)
<shared lib "persistence">
 -> declares a datamodel shared by different applications including the UserEntity

For any reason the creation of the JpaRepository thinks, that there is a property 'newDslAlias' in the UserEntity class, but until now I could not find any reason for that. I would be happy for help.

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'securityUserRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Failed to create query for method public abstract java.lang.Object io.oasp.module.jpa.dataaccess.api.data.QueryDslSupport.newDslAlias()!

Got it to work :/

If you want to have reusable JPARepository implementations in separate modules, you have to always specify @EnableJpaRepositories(repositoryFactoryBeanClass = GenericRepositoryFactoryBean.class) again and again although the SpringBootApp already comes with this repositoryFactoryBeanClass configured...

Sorry, I did not see this earlier. Seems you figured it out yourself. That is nice. However, I do not get where you had to specify the @EnableJpaRepositories again and again in your code?
I only have one SpringBootApp per application even it is modularized. Are you talking about JUnit configs? Arent you following devonfw and using the SpringBootApp itself as config for component and subsystem tests? Maybe we can derive some learning or a documentation hint from this problem.

[hohwille]

The stacktrace from spring-data and esp. the root cause error message is kind of confusing, but if you read it carefully you get that the repository does not implement newDslAlias. That is what only happens if GenericRepositoryFactoryBean is used to create the repository.
In case you want to modularize and have repositories in different maven modules that you also want to test within their defining module, I would create an abstract configuration / spring app that defines the basic configuration setup like the jpa repo config and derive both your test configs as well as your real SpringBootApp from it.
