<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-ldap</artifactId>
</dependency>

spring.ldap.urls=ldap://ldap.example.com:389
spring.ldap.username=cn=admin,dc=example,dc=com
spring.ldap.password=secret

@Entry(base = "ou=users", objectClasses = "inetOrgPerson")
public class User {
    @Id
    private Name dn;
    private String uid;
    private String cn;
    private String sn;
    // 其他属性...
    // getter和setter方法...
}

public interface UserRepository extends LdapRepository<User> {
    Optional<User> findByUid(String uid);
    // 其他查询方法...
}

@Service
public class UserService {
    private final UserRepository userRepository;

    public UserService(UserRepository userRepository) {
        this.userRepository = userRepository;
    }

    public User getUserByUid(String uid) {
        Optional<User> userOptional = userRepository.findByUid(uid);
        return userOptional.orElse(null);
    }
}
