Constructor Details

JpaRepositoryFactory

public JpaRepositoryFactory(jakarta.persistence.EntityManager entityManager)

Creates a new JpaRepositoryFactory.

Parameters:

entityManager - must not be null

Method Details

setBeanClassLoader

public void setBeanClassLoader(ClassLoader classLoader)

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

Overrides:

setBeanClassLoader in class RepositoryFactorySupport

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)
                    throws BeansException

If a BeanFactory is being set, this is clearly in a Spring context, and so we can capture the QueryRewriterProvider being a BeanFactoryQueryRewriterProvider.

Specified by:

setBeanFactory in interface BeanFactoryAware

Overrides:

setBeanFactory in class RepositoryFactorySupport

Parameters:

beanFactory -

Throws:

BeansException

setEntityPathResolver

public void setEntityPathResolver(EntityPathResolver entityPathResolver)

Configures the EntityPathResolver to be used. Defaults to SimpleEntityPathResolver.INSTANCE.

Parameters:

entityPathResolver - must not be null.

setEscapeCharacter

public void setEscapeCharacter(EscapeCharacter escapeCharacter)

Configures the escape character to be used for like-expressions created for derived queries.

Parameters:

escapeCharacter - a character used for escaping in certain like expressions.

setQueryMethodFactory

public void setQueryMethodFactory(JpaQueryMethodFactory queryMethodFactory)

Configures the JpaQueryMethodFactory to be used. Defaults to DefaultJpaQueryMethodFactory.

Parameters:

queryMethodFactory - must not be null.

setQueryRewriterProvider

public void setQueryRewriterProvider(QueryRewriterProvider queryRewriterProvider)

Configures the QueryRewriterProvider to be used. Defaults to instantiate query rewriters through BeanUtils.instantiateClass(Class).

Parameters:

queryRewriterProvider - must not be null.

Since:

3.0

getTargetRepository

protected final JpaRepositoryImplementation<?,?> getTargetRepository(RepositoryInformation information)

Specified by:

getTargetRepository in class RepositoryFactorySupport

getTargetRepository

protected JpaRepositoryImplementation<?,?> getTargetRepository(RepositoryInformation information,
 jakarta.persistence.EntityManager entityManager)

Callback to create a JpaRepository instance with the given EntityManager

Parameters:

information - will never be null.

entityManager - will never be null.

Returns:

getRepositoryBaseClass

protected Class<?> getRepositoryBaseClass(RepositoryMetadata metadata)

Specified by:

getRepositoryBaseClass in class RepositoryFactorySupport

getProjectionFactory

protected ProjectionFactory getProjectionFactory(ClassLoader classLoader,
 BeanFactory beanFactory)

Overrides:

getProjectionFactory in class RepositoryFactorySupport

getQueryLookupStrategy

protected Optional<QueryLookupStrategy> getQueryLookupStrategy(@Nullable
 QueryLookupStrategy.Key key,
 QueryMethodEvaluationContextProvider evaluationContextProvider)

Overrides:

getQueryLookupStrategy in class RepositoryFactorySupport

getEntityInformation

public <T,
ID> JpaEntityInformation<T,ID> getEntityInformation(Class<T> domainClass)

Specified by:

getEntityInformation in class RepositoryFactorySupport

getRepositoryFragments

protected RepositoryComposition.RepositoryFragments getRepositoryFragments(RepositoryMetadata metadata)

Overrides:

getRepositoryFragments in class RepositoryFactorySupport

getRepositoryFragments

protected RepositoryComposition.RepositoryFragments getRepositoryFragments(RepositoryMetadata metadata,
 jakarta.persistence.EntityManager entityManager,
 EntityPathResolver resolver,
 CrudMethodMetadata crudMethodMetadata)

Creates RepositoryComposition.RepositoryFragments based on RepositoryMetadata to add JPA-specific extensions. Typically adds a QuerydslJpaPredicateExecutor if the repository interface uses Querydsl.

Can be overridden by subclasses to customize RepositoryComposition.RepositoryFragments.

Parameters:

metadata - repository metadata.

entityManager - the entity manager.

resolver - resolver to translate a plain domain class into a EntityPath.

crudMethodMetadata - metadata about the invoked CRUD methods.

Returns:
