For the latest stable version, please use Spring Data LDAP 3.4.0!spring-doc.cn

Usage

To access domain entities stored in a LDAP-compliant directory, you can use our sophisticated repository support that significantly eases implementation. To do so, create an interface for your repository, as the following example shows:spring-doc.cn

Example 1. Sample Person entity

@Entry(objectClasses = { "person", "top" }, base="ou=someOu")
public class Person {

   @Id
   private Name dn;

   @Attribute(name="cn")
   @DnAttribute(value="cn", index=1)
   private String fullName;

   @Attribute(name="firstName")
   private String firstName;

   // No @Attribute annotation means this is bound to the LDAP attribute
   // with the same value
   private String firstName;

   @DnAttribute(value="ou", index=0)
   @Transient
   private String company;

   @Transient
   private String someUnmappedField;
   // ...more attributes below
}

We have a simple domain object here. Note that it has a property named dn of type Name. With that domain object, we can create a repository to persist objects of that type by defining an interface for it, as follows:spring-doc.cn

Example 2. Basic repository interface to persist Person entities

public interface PersonRepository extends CrudRepository<Person, Long> {

  // additional custom finder methods go here
}

Because our domain repository extends CrudRepository, it provides you with CRUD operations as well as methods for access to the entities. Working with the repository instance is a matter of dependency injecting it into a client.spring-doc.cn

Example 3. Access to Person entities

@ExtendWith(SpringExtension.class)
@ContextConfiguration
class PersonRepositoryTests {

    @Autowired PersonRepository repository;

    @Test
    void readAll() {

      List<Person> persons = repository.findAll();
      assertThat(persons.isEmpty(), is(false));
    }
}

The sample creates an application context with Spring’s unit test support, which will perform annotation-based dependency injection into test cases. Inside the test method, we use the repository to query the datastore.spring-doc.cn
