根据Spring Data JPA文档（https：//docs.spring.io/spring-data/jpa/docs/current/reference/html/#jpa.query-methods.query-creation），可以将实体集合传递给IN和NOT IN子句。
x1c 0d1x的数据
Age是一个实体。然而，在实践中，这似乎是不可能的。
克隆GitHub repo，或者只是复制并粘贴下面的实体来复制。下面是一个示例：

import jakarta.persistence.*;

@Entity
@Table(name = "specialties")
public class Specialty {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", nullable = false)
    private Long id;

    @Column(name = "name")
    private String name;
}
import jakarta.persistence.*;

import java.util.Set;

@Entity
@Table(name = "vets")
public class Vet {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", nullable = false)
    private Long id;

    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(
            name = "vet_specialties",
            joinColumns = @JoinColumn(name = "vet_id"),
            inverseJoinColumns = @JoinColumn(name = "specialty_id")
    )
    private Set<Specialty> specialties;

    public void addSpecialty(Specialty specialty) {
        this.specialties.add(specialty);
    }
}
import com.example.demo.entity.Specialty;
import org.springframework.data.jpa.repository.JpaRepository;

public interface SpecialtyRepository extends JpaRepository<Specialty, Long> {
}

字符串
关键时刻：

import com.example.demo.entity.Specialty;
import com.example.demo.entity.Vet;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Query;

import java.util.Collection;
import java.util.List;

public interface VetRepository extends JpaRepository<Vet, Long> {

    @Query("select v from Vet v where v.specialties in ?1")
    List<Vet> findBySpecialtiesIn(Collection<Specialty> specialties);

}

如你所见，我正试着按专业来接兽医。
下面是对它的测试：

@SpringBootApplication
public class DemoApplication implements CommandLineRunner {

    private final SpecialtyRepository specialtyRepository;
    private final VetRepository vetRepository;

    public DemoApplication(SpecialtyRepository specialtyRepository,
                           VetRepository vetRepository) {
        this.specialtyRepository = specialtyRepository;
        this.vetRepository = vetRepository;
    }

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

    @Override
    public void run(String... args) {
        Set<Specialty> specialties = new HashSet<>();
        specialties.add(new Specialty());
        specialties.add(new Specialty());
        specialties.add(new Specialty());
        specialties.add(new Specialty());

        specialtyRepository.saveAll(specialties);

        Vet vet = new Vet();

        specialties.forEach(vet::addSpecialty);

        vetRepository.save(vet);

        vetRepository.findBySpecialtiesIn(specialties);
    }
}

我得到以下错误：

我的问题很简单。这只是文档中的错别字，还是我做错了什么？

你不明白对吧，如何使用IN或NOT IN你不能用它来ManyToMany关系：要使用IN或NOT IN，你应该有这样的东西：
