我在Sping Boot 项目中有以下Movie类,它包含演员列表。我想确保演员不会被删除,如果它是电影的一部分,我想通过JPA/Hibernate在数据库级别上强制执行此约束。然而,当我导入jakarta.persistence.Check
时,编译器无法识别它,即使我在gradle中有正确的依赖关系。我假设这是版本控制问题,但我不能。I don’我无法解决这个问题。
import jakarta.persistence.*;
import jakarta.persistence.Check;
import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;
import java.time.LocalDate;
import java.util.HashSet;
import java.util.Set;
@Entity
@Table(name = "movies",
uniqueConstraints = @UniqueConstraint(columnNames = {"title", "releaseDate"}))
public class Movie extends Media {
@Column(nullable = false)
private String title;
@Column(nullable = false)
private LocalDate releaseDate;
@ManyToMany(fetch = FetchType.LAZY)
@JoinTable(
name = "movie_actor",
joinColumns = @JoinColumn(name = "movie_id"),
inverseJoinColumns = @JoinColumn(name = "actor_id"),
uniqueConstraints = {@UniqueConstraint(columnNames = {"movie_id", "actor_id"})},
foreignKey = @ForeignKey(name = "fk_movie"),
inverseForeignKey = @ForeignKey(name = "fk_actor"),
// add check constraint to ensure actor is not deleted if part of any movie
constraints = @Check(constraints = "NOT EXISTS(SELECT * FROM movie_actor ma WHERE ma.actor_id = id)")
)
private Set<Actor> actors = new HashSet<>();
}

Jakarta Persistence API从来没有定义过
@Check
注解。所以,jakarta.persistence.Check
在2.3和3.x规范中都不存在。最新的规范是here,源代码是here。我假设您想使用
org.hibernate.annotations.Check
有关详细信息,请访问此链接:https://docs.jboss.org/hibernate/orm/5.5/userguide/html_single/Hibernate_User_Guide.html#schema-generation-database-checks。最后,我想指出这段代码的一些重要部分。
spring-data-jpa:3.0.4
有一个可选的依赖项hibernate-core:6.1.4.Final
。这是因为我推荐使用Hibernate 6.x。1.您在依赖项中定义了两个不兼容的JPA API:
javax.persistence:javax.persistence-api:2.2
和jakarta.persistence:jakarta.persistence-api:3.1.0
Spring Framework 6和Sping Boot 3都完全兼容Jakarta EE 9。在Jakarta堆栈上使用任何javax.*
依赖项都可能导致问题。
