[英]Hibernate JPA “Associated class not found” using another Entity as Key and Embeddable as Value
我将 Spring-Boot-Web 2.3.6.RELEASE 与 JPA Starter 和 Postgres 一起使用。
在启动时，我得到以下 Hibernate-Exception：
2021-01-24 22:53:23.606 ERROR 2026 --- [ restartedMain] o.s.boot.SpringApplication : Application run failed

还有我的实体类：
加密密钥
package io.share.backend.repository.model;
import lombok.Data;
import javax.persistence.*;
import java.io.Serializable;
@Data
@Entity
@Table(name = "encryption_key")
public class EncryptionKey implements Serializable {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "encryption_key_id_seq")
@SequenceGenerator(name = "encryption_key_id_seq", sequenceName = "encryption_key_id_seq", allocationSize = 1)
private long id;
@Column(name = "raw")
private byte[] raw;
@Column(name = "algorithm")
private String algorithm;
}
帐户
package io.share.backend.repository.model;
import lombok.Data;
import javax.persistence.*;
import java.io.Serializable;
import java.time.Instant;
@Data
@Entity
@Table(name = "account")
public class Account implements Serializable {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "account_id_seq")
@SequenceGenerator(name = "account_id_seq", sequenceName = "account_id_seq", allocationSize = 1)
private long id;
@Column(name = "issuer")
private String issuer;
@Column(name = "name")
private String name;
@Column(name = "registration_time")
private Instant registrationTime;
@Column(name = "display_name")
private String displayName;
@Column(name = "storage_root")
private String storageRoot;
@ManyToOne
@JoinColumn(name = "encryption_key_id", nullable = false)
private EncryptionKey encryptionKey;
}
基本实体
package io.share.backend.repository.model;
import lombok.Data;
import javax.persistence.*;
import java.io.Serializable;
import java.time.Instant;
import java.util.Map;
@Data
@Entity
@Table(name = "entity")
@Inheritance(strategy = InheritanceType.JOINED)
public class BaseEntity implements Serializable {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "entity_id_seq")
@SequenceGenerator(name = "entity_id_seq", sequenceName = "entity_id_seq", allocationSize = 1)
private long id;
@ManyToOne
@JoinColumn(name = "owner_account_id", nullable = false, updatable = false)
private Account ownerAccount;
@Column(name = "name")
private String name;
@Column(name = "creation_time")
private Instant creationTime;
@Column(name = "type")
private Type type;
@ElementCollection
@CollectionTable(name = "entity_tag", joinColumns = @JoinColumn(name = "entity_id", referencedColumnName = "id"))
@MapKeyColumn(name = "key")
@Column(name = "value")
private Map<String, String> tags;
public enum Type {
FOLDER,
OBJECT,
VIEW,
VIEW_EXPORT
}
}
实体共享
package io.share.backend.repository.model;
import lombok.Data;
import javax.persistence.*;
import java.time.Instant;
import java.util.Map;
@Data
@Entity
@Table(name = "entity_share")
public class EntityShare {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "entity_share_id_seq")
@SequenceGenerator(name = "entity_share_id_seq", sequenceName = "entity_share_id_seq", allocationSize = 1)
private long id;
@ManyToOne
@JoinColumn(name = "entity_id", nullable = false, updatable = false)
private BaseEntity entity;
@Column(name = "open_entry_count")
private int openEntryCount;
@Column(name = "permission_flags")
private int permissionFlags;
@ElementCollection
@CollectionTable(name = "entity_share_entry", joinColumns = @JoinColumn(name = "entity_share_id", referencedColumnName = "id"))
@MapKey(name = "entry_account_id")
private Map<Account, EntityShareEntry> entries;
@Data
@Embeddable
public static class EntityShareEntry {
@Column(name = "entry_time")
private Instant entryTime;
}
}
将我的EntityShare -Entity 更改为：
package io.share.backend.repository.model;
import lombok.Data;
import javax.persistence.*;
import java.time.Instant;
import java.util.Map;
@Data
@Entity
@Table(name = "entity_share")
public class EntityShare {
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "entity_share_id_seq")
@SequenceGenerator(name = "entity_share_id_seq", sequenceName = "entity_share_id_seq", allocationSize = 1)
private long id;
@ManyToOne
@JoinColumn(name = "entity_id", nullable = false, updatable = false)
private BaseEntity entity;
@Column(name = "open_entry_count")
private int openEntryCount;
@Column(name = "permission_flags")
private int permissionFlags;
@ElementCollection
@CollectionTable(name = "entity_share_entry", joinColumns = @JoinColumn(name = "entity_share_id", referencedColumnName = "id"))
@MapKeyColumn(name = "entry_account_id")
@Column(name = "entry_time")
private Map<Long, Instant> entries;
}
它似乎有效，但我希望（如果可能的话）实际 Account 作为键，并且还有机会添加更多字段，而不仅仅是将 entry_time 作为未来的值。
像我现在这样的地图参考是否可行？ 如果是，如何？ 如果不是，我怎么可能使用 JPA 以另一种方式表示这一点？
尝试纠正这一点：
@ElementCollection
@CollectionTable(name = "entity_share_entry", joinColumns = @JoinColumn(name = "entity_share_id", referencedColumnName = "id"))
@MapKey(name = "entry_account_id")
private Map<Account, EntityShareEntry> entries;
对此：
@ElementCollection
@CollectionTable(name = "entity_share_entry", joinColumns = @JoinColumn(name = "entity_share_id", referencedColumnName = "id"))
@MapKeyJoinColumn(name = "entry_account_id")
private Map<Account, EntityShareEntry> entries;
另请注意，Embeddable 和 Entity 类必须是顶级类（参见 JPA 规范的第 2.5 和 2.1 节）
是否可以在没有 @Embeddable 的情况下将 JPA/休眠实体字段 map 转换为另一个 class 中的字段？
[英]Is it possible to map a JPA/Hibernate Entity field to a field in another class without @Embeddable?
JPA映射一个包含Map的Embeddable类<Entity, Embeddable>
