public QuerydslJpaRepository(JpaEntityInformation<T,ID> entityInformation,
                             javax.persistence.EntityManager entityManager)

Creates a new QuerydslJpaRepository from the given domain class and EntityManager. This will use the SimpleEntityPathResolver to translate the given domain class into an EntityPath.

Parameters:

entityInformation - must not be null.

entityManager - must not be null.

QuerydslJpaRepository

public QuerydslJpaRepository(JpaEntityInformation<T,ID> entityInformation,
                             javax.persistence.EntityManager entityManager,
                             EntityPathResolver resolver)

Creates a new QuerydslJpaRepository from the given domain class and EntityManager and uses the given EntityPathResolver to translate the domain class into an EntityPath.

Parameters:

entityInformation - must not be null.

entityManager - must not be null.

resolver - must not be null.
