java - 忽略更新查询中的 createdBy 和 CreatedDate

Question

我正在使用 spring r2dbc 和 ReactiveCrudRepository，如何在更新查询中忽略 createdBy 和 CreatedDate。

@Data
public class Base {
    @Id
     private long id;
   
     @JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss")
     @Column("created_on")
     @CreatedDate
     private LocalDateTime createdOn;
 
     @Column("created_by")
     @CreatedBy
     private Long createdBy;
 
     @JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss")
     @Column("updated_on")
     @LastModifiedDate
     private LocalDateTime updatedOn;
 
     @Column("updated_by")
     @LastModifiedBy
     private Long updatedBy;
}

Answer 1

你可以像这样使用@Transient注解:

...
import org.springframework.data.annotation.Transient;
...
@Data
public class Base {
  @Id
  private long id;

  @JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss")
  @Column("created_on")
  @CreatedDate
  @Transient
  private LocalDateTime createdOn;

  @Column("created_by")
  @CreatedBy
  @Transient 
  private Long createdBy;

  @JsonFormat(pattern = "yyyy-MM-dd'T'HH:mm:ss")
  @Column("updated_on")
  @LastModifiedDate
  private LocalDateTime updatedOn;

  @Column("updated_by")
  @LastModifiedBy`enter code here`
  private Long updatedBy;
}
