我无法定义如何在另一个表的实体类中映射两个不同表的两个外键列

Question

Iam unable to define how to map two foreign key columns of two different table in Entity class of other table.

let me give example of table structure

table1
   column11 (primary key)
   column12 
   column13

table2
   column21 (primary key)
   column11 (foreign key - table1 primary key column)
   column22
   column23

table3
   column31 (primary key)
   column11 (foreign key - table1 primary key column)
   column21 (foreign key - table2 primary key column)
   column32
   column33

Now i want to my entity class table3 to hold these two foreign keys. Iam very new to JPA(hibernate) . How can i map those foreign key columns as entity class attributes? Please suggest me.

Answer 1

@Entity
public class Table3 {
    // ...

    @ManyToOne
    @JoinColumn(name = "column11")
    private Table1 table1;

    @ManyToOne
    @JoinColumn(name = "column21")
    private Table2 table2;

    // ...
}
