      public ProjectionAutoConfiguration()

  • Method Details

    • projectionMetadataRegistry

      @Bean public ProjectionMetadataRegistry projectionMetadataRegistry()
      Provides a ProjectionMetadataRegistry that can be used to access compile-time generated metadata for projections. If the GeneratedProjectionMetadataRegistry class is not found, it falls back to a SimpleProjectionMetadataRegistry.
      Returns:
      the ProjectionMetadataRegistry instance

    • criteriaProjectionBuilder

      @Bean public CriteriaProjectionBuilder criteriaProjectionBuilder(ProjectionMetadataRegistry registry)
      Provides a CriteriaProjectionBuilder that uses ProjectionMetadataRegistry to access compile-time generated metadata. This builder can be used to construct JPA Criteria API expressions for projections.
      Parameters:
      registry - the ProjectionMetadataRegistry to use for accessing metadata
      Returns:
      the CriteriaProjectionBuilder instance

    • querydslProjectionBuilder

      @Bean public QuerydslProjectionBuilder querydslProjectionBuilder(ProjectionMetadataRegistry registry)
      Provides a QuerydslProjectionBuilder that uses ProjectionMetadataRegistry to access compile-time generated metadata. This builder can be used to construct QueryDSL expressions for projections.
      Parameters:
      registry - the ProjectionMetadataRegistry to use for accessing metadata
      Returns:
      the QuerydslProjectionBuilder instance

    • jpaProjectionExecutorProvider

      @Bean @ConditionalOnBean(jakarta.persistence.EntityManager.class) @ConditionalOnProperty(prefix="crudcraft.projection", name="engine", havingValue="CRITERIA", matchIfMissing=true) public ProjectionExecutorProvider jpaProjectionExecutorProvider(jakarta.persistence.EntityManager entityManager, CriteriaProjectionBuilder criteriaBuilder, ProjectionMetadataRegistry registry, ProjectionProperties properties)
      Provides a JpaProjectionExecutorProvider that uses JPA Criteria API for projections. This provider is only created if an EntityManager bean is available.
      Parameters:
      entityManager - the EntityManager to use for executing queries
      criteriaBuilder - the CriteriaProjectionBuilder to build projection expressions
      registry - the ProjectionMetadataRegistry to access compile-time generated metadata
      properties - the ProjectionProperties to configure the projection engine
      Returns:
      the JpaProjectionExecutorProvider instance

    • querydslProjectionExecutorProvider

      @Bean @ConditionalOnBean(com.querydsl.jpa.impl.JPAQueryFactory.class) @ConditionalOnProperty(prefix="crudcraft.projection", name="engine", havingValue="QUERYDSL") public ProjectionExecutorProvider querydslProjectionExecutorProvider(com.querydsl.jpa.impl.JPAQueryFactory queryFactory, jakarta.persistence.EntityManager entityManager, QuerydslProjectionBuilder querydslBuilder, ProjectionMetadataRegistry registry, ProjectionProperties properties)
      Provides a QuerydslProjectionExecutorProvider that uses QueryDSL for projections. This provider is only created if a JPAQueryFactory bean is available.
      Parameters:
      queryFactory - the JPAQueryFactory to use for executing queries
      entityManager - the EntityManager to access the JPA metamodel
      querydslBuilder - the QuerydslProjectionBuilder to build projection expressions
      registry - the ProjectionMetadataRegistry to access compile-time generated metadata
      properties - the ProjectionProperties to configure the projection engine
      Returns:
      the QuerydslProjectionExecutorProvider instance

    • projectionExecutor

      @Bean @ConditionalOnBean(ProjectionExecutorProvider.class) public ProjectionExecutor projectionExecutor(List<ProjectionExecutorProvider> providers)
      Provides a ProjectionExecutor that routes to the appropriate executor based on the available ProjectionExecutorProviders. If only one provider is available, it returns that executor directly. If multiple providers are available, it returns a RoutingProjectionExecutor that delegates to the appropriate provider based on the query type.
      Parameters:
      providers - the list of ProjectionExecutorProviders
      Returns:
      the ProjectionExecutor instance
