For the latest stable version, please use Spring LDAP 3.2.10!

Spring LDAP Repositories

Spring LDAP has built-in support for Spring Data repositories. The basic functionality and configuration is described here. When working with Spring LDAP repositories, you should remember the following:

  • You can enable Spring LDAP repositories by using an <ldap:repositories> element in your XML configuration or by using an @EnableLdapRepositories annotation on a configuration class.

  • To include support for LdapQuery parameters in automatically generated repositories, have your interface extend LdapRepository rather than CrudRepository.

  • All Spring LDAP repositories must work with entities that are annotated with the ODM annotations, as described in Object-Directory Mapping (ODM).

  • Since all ODM managed classes must have a Distinguished Name as the ID, all Spring LDAP repositories must have the ID type parameter set to javax.naming.Name. The built-in LdapRepository takes only one type parameter: the managed entity class, defaulting the ID to javax.naming.Name.

  • Due to specifics of the LDAP protocol, paging and sorting are not supported for Spring LDAP repositories.

QueryDSL support

Basic QueryDSL support is included in Spring LDAP. This support includes the following:

  • An annotation processor, called LdapAnnotationProcessor, for generating QueryDSL classes based on Spring LDAP ODM annotations. See Object-Directory Mapping (ODM) for more information on the ODM annotations.

  • A Query implementation, called QueryDslLdapQuery, for building and running QueryDSL queries in code.

  • Spring Data repository support for QueryDSL predicates. QueryDslPredicateExecutor includes a number of additional methods with appropriate parameters. You can extend this interface along with LdapRepository to include this support in your repository.
