使用 Hibernate 从 MS SQL 检索值而不执行 CRUD 操作的创建

Question

Let's say I have this existing data in MS SQL,

debt

  id          can           bdrl_debt    excess_ta_debt      posting_ref   debt_settlement_id   debt_settlement_at       debt_business_date
  
11425   1099112400000003        0              200             501728             137        2020-10-13 10:51:50.000         2020-10-13 

How do I retrieve and print out the data in such a way that I do not have to perform the Create of the CRUD operation? Can anybody enlighten me on how to do that?

Note: Connection is fine. I'm using AnnotationMapping with Entity Class.

Answer 1

I finally managed to retrieve the data from MS SQL using String to map variables with the database.

Here is the snippet of the output:

Entity Class

@Data
@Entity
@Table(name = "dbo.debt")
public class AbtDebtbbyCAN implements Serializable{

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id")
    private int debt_id;

    @Column(name = "can")
    private int debt_can;

}

In order for it to be printed in the output, make sure the variables are using String data type so it could be deserialized. Hope this answers your question.
