How can I fix bugs in Custom Repository? - spring-boot

Question

I'm trying to make a Custom Repository with spring-data-jpa.
My codes
Repository
#NoRepositoryBean
interface CustomRepository<T, ID : Serializable> : JpaRepository<T, ID> {
fun findBySomeRestrict(id: ID): T?
}
RepositoryImpl
#Transactional(readOnly = true)
class CustomRepositoryImpl<T, ID : Serializable>(
private val entityManager: EntityManager,
jpaEntityInformation: JpaMetamodelEntityInformation<T, ID>
) : SimpleJpaRepository<T, ID>(jpaEntityInformation, entityManager), CustomRepository<T, ID> {
override fun findBySomeRestrict(id: ID): T? {
// TODO
}
}
Main class
#EnableJpaAuditing
#EnableJpaRepositories(repositoryBaseClass = CustomRepositoryImpl::class)
#SpringBootApplication
class ForSubmitApplication
fun main(args: Array<String>) {
runApplication<ForSubmitApplication>(*args)
}
MyErrorMessage
Caused by: java.lang.IllegalStateException: No suitable constructor found on interface com.example.forsubmit.global.custom.CustomRepository to match the given arguments: org.springframework.data.jpa.repository.support.JpaMetamodelEntityInformation, jdk.proxy2.$Proxy132.

What I do to fix it
Change the type of constructor to JpaEntityInformation
Decompile the code

Answer 1

It seems you only want to provide the implementation of one method.
In that case you must not set repositoryBaseClass.
Instead you want to follow the steps outlined in the documentation.
Create an interface just containing the custom method(s). You currently don't have that.
Create an implementation of it. You are currently implementing the final Repository interface which is wrong.
Extend your final repository interface from the custom interface created in step 1.
