Spring數據審計和@Embedded JPA

我對JPA審計和@Embedded成員有問題。考慮以下示例場景：Spring數據審計和@Embedded JPA

我成立了一個Oracle數據庫的測試表：

CREATE TABLE AUDIT_TEST (
    ID   NUMBER(38) NOT NULL PRIMARY KEY, 
    CREATION_DATE TIMESTAMP(6) DEFAULT SYSTIMESTAMP NOT NULL 
);

我定義了一個JPA @Entity與審計：

@Entity 
@EntityListeners(AuditingEntityListener.class) 
@Table(name = "AUDIT_TEST") 
public class AuditTest { 

    private Long id; 
    private LocalDateTime creationDate; 

    @Id 
    @Column(name = "ID") 
    public Long getId() { return id; } 

    public void setId(Long id) { this.id = id; } 

    @CreatedDate 
    @Column(name = "CREATION_DATE") 
    public LocalDateTime getCreationDate() { return creationDate; } 

    public void setCreationDate(LocalDateTime creationDate) { 
    this.creationDate = creationDate; 
    } 

}

最後，我啓用JPA審計我@Configuration：

@SpringBootApplication() 
@EnableJpaAuditing() 
public class AuditTestApplication { 
}

到目前爲止好;當我構造一個AuditTest實例時，爲其分配一個ID並提交，creationDate列將按照預期填充當前時間戳。

然而，事情停止工作時，我封裝在一個@Embeddable審計列：

@Embeddable 
public class AuditTestEmbeddable { 

    private LocalDateTime creationDate; 

    @CreatedDate 
    @Column(name = "CREATION_DATE") 
    public LocalDateTime getCreationDate() { return creationDate; } 

    public void setCreationDate(LocalDateTime creationDate) { 
    this.creationDate = creationDate; 
    } 

}

然後我改變我的實體類嵌入創建日期：

@Entity 
@EntityListeners(AuditingEntityListener.class) 
@Table(name = "AUDIT_TEST") 
public class AuditTest { 

    private Long id; 
    private AuditTestEmbeddable auditTestEmbeddable = new AuditTestEmbeddable(); 

    @Id 
    @Column(name = "ID") 
    public Long getId() { return id; } 

    public void setId(Long id) { this.id = id; } 

    @Embedded 
    public AuditTestEmbeddable getAuditTestEmbeddable() { 
    return auditTestEmbeddable; 
    } 

    public void setAuditTestEmbeddable(AuditTestEmbeddable auditTestEmbeddable) { 
    this.auditTestEmbeddable = auditTestEmbeddable; 
    } 

}

不幸的是，審計已不再工作。

有沒有人知道在保留審計功能的同時仍然使用@Embedded類的方法？

信息必須在託管實體上（至少這是如何完成和現在的工作）。所以目前沒有其他方法可以直接將其添加到實體中。 –

你好，所以唯一可用的選擇是直接向每個實體添加所需的字段，例如：用戶創建者，用戶更新者，日期creationDate，日期updateDate？這是對的嗎？ – Paolo

Spring嵌套（可嵌入）類中的數據審計註釋尚不受支持。請求此功能the jira ticket。

但是，我們可以使用自定義審計偵聽器在可嵌入類中設置審計信息。

下面是從博客取得的示例實現：How to audit entity modifications using the JPA @EntityListeners, @Embedded, and @Embeddable annotations。

嵌入審計

@Embeddable 
public class Audit { 

    @Column(name = "created_on") 
    private LocalDateTime createdOn; 

    @Column(name = "created_by") 
    private String createdBy; 

    @Column(name = "updated_on") 
    private LocalDateTime updatedOn; 

    @Column(name = "updated_by") 
    private String updatedBy; 

    //Getters and setters omitted for brevity 
}

審計監聽

public class AuditListener { 

    @PrePersist 
    public void setCreatedOn(Auditable auditable) { 
     Audit audit = auditable.getAudit(); 

     if(audit == null) { 
      audit = new Audit(); 
      auditable.setAudit(audit); 
     } 

     audit.setCreatedOn(LocalDateTime.now()); 
     audit.setCreatedBy(LoggedUser.get()); 
    } 

    @PreUpdate 
    public void setUpdadtedOn(Auditable auditable) { 
     Audit audit = auditable.getAudit(); 

     audit.setUpdatedOn(LocalDateTime.now()); 
     audit.setUpdatedBy(LoggedUser.get()); 
    } 
}

可審計

public interface Auditable { 

    Audit getAudit(); 

    void setAudit(Audit audit); 
}

示例實體

@Entity 
@EntityListeners(AuditListener.class) 
public class Post implements Auditable { 

    @Id 
    private Long id; 

    @Embedded 
    private Audit audit; 

    private String title; 

    }
