Spring Boot Jpastreamer - com.speedment.jpastreamer.application.JPAStreamer can not be found

Question

I have a problem to run my Spring Boot with the usage of Jpastreamer. I cannot solve the bean issue related with Jpastreamer.

Here is the PersonService shown below

@Service
@RequiredArgsConstructor
public class PersonService {

    private final JPAStreamer jpaStreamer;
    private final PersonRepository personRepository;

    ... 
}

I got this issue shown below when I run the application.

Answer 1

After defining JPAStreamer as a bean in JPAStreamerConfig shown below, the issue disappeared.

import com.speedment.jpastreamer.application.JPAStreamer;
import jakarta.persistence.EntityManagerFactory;
import lombok.RequiredArgsConstructor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@RequiredArgsConstructor
public class JPAStreamerConfig {

    private final EntityManagerFactory entityManagerFactory;

    @Bean
    public JPAStreamer jpaStreamer() {
        return JPAStreamer.of(entityManagerFactory);
    }

}
