QuerydlsApplicationTests.java는 이렇습니다.

ackage study.querydsl;

import com.querydsl.jpa.impl.JPAQueryFactory;

import jakarta.persistence.EntityManager;
import jakarta.transaction.Transactional;
import org.assertj.core.api.Assertions;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import study.querydsl.entity.Hello;
import study.querydsl.entity.QHello;

import static org.assertj.core.api.Assertions.*;

@SpringBootTest
@Transactional
class QuerydslApplicationTests {

@Autowired
EntityManager em;
@Test
void contextLoads() {
Hello hello = new Hello();
em.persist(hello);

JPAQueryFactory query = new JPAQueryFactory(em);
QHello qHello = new QHello("h");

Hello result = query.selectFrom(qHello)
.fetchOne();

assertThat(result).isEqualTo(hello);
assertThat(result.getId()).isEqualTo(hello.getId());
}

}

hello.java 입니다

package study.querydsl.entity;

import jakarta.persistence.Entity;
import jakarta.persistence.GeneratedValue;
import jakarta.persistence.Id;
import lombok.Getter;
import lombok.Setter;
@Entity
@Getter @Setter
public class Hello {

@Id

private Long id;

}

어떻게 해야 하나요?
