Hibernate Search is required javax.persistence.EntityManager

Question

I'm trying make test application using Hibernate Search. I have note repository which extend SimpleJpaRepository with required parameter jakarta.persistence.EntityManager. But when i try to create search session Search.session(entityManager) I get an error that the Search.session() need javax.persistence.EntityManager. So question is how can i create Search session using jakarta.persistence.EntityManager?

NoteRepository:

@Repository
@Transactional
class NoteRepositoryImpl(
    private val entityManager: EntityManager,
) : SimpleJpaRepository<NoteEntity, Long>(NoteEntity::class.java, entityManager), NoteRepository {

    override fun search(query: String): List<NoteEntity> {
        val session = Search.session(entityManager)

        val result = session.search(NoteEntity::class.java)
            .where { it.match().fields("title", "tag", "content").matching(query) }
            .fetch(0, 100)
        return result.hits().map { it as NoteEntity }
    }
}

Gradle file:

plugins {
    id 'org.springframework.boot' version '3.0.4'
    id 'io.spring.dependency-management' version '1.1.0'

Since you are using Spring Boot 3, which is based on jakarta.* you'd need to use a jakarta version of orm-mapper:

implementation 'org.hibernate.search:hibernate-search-mapper-orm-jakarta:6.1.8.Final'
