Spring Data JPA incorrectly derives query for custom base repository method getObj, causing "No property 'getObj' found for type 'User'"

[xiaobin8811]

Summary

When defining a custom base repository interface plus implementation, Spring Data JPA attempts to derive a query from a non-derived method name and fails with:

No property 'getObj' found for type 'User'

Environment

• Spring Boot: 4.0.0
• Java: 25
• OS: macOS

Code Snippet

@SpringBootApplication
@EnableJpaRepositories(
    basePackages = "com.example.demo.dao",
    repositoryFactoryBeanClass = CustomBaseRepositoryFactoryBean.class
)
public class DemoApplication {
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

@NoRepositoryBean
public interface BaseDao<T, ID extends Serializable>
        extends JpaRepository<T, ID>, JpaSpecificationExecutor<T> {
    T getObj(ID id);
}

public class BaseDaoImpl<T, ID extends Serializable>
        extends SimpleJpaRepository<T, ID>
        implements BaseDao<T, ID> {

    private final EntityManager entityManager;

    public BaseDaoImpl(JpaEntityInformation<T, ?> entityInformation,
                       EntityManager entityManager) {
        super(entityInformation, entityManager);
        this.entityManager = entityManager;
    }

    @Override
    public T getObj(ID id) {
        return findById(id).orElse(null);
    }
}

User repository:

public interface UserDao extends BaseDao<User, Long> {}

Observed Behavior

Application fails to start with:

org.springframework.beans.factory.UnsatisfiedDependencyException: ...
No property 'getObj' found for type 'User'
