Jooq：如何将具有相同列名的Record映射到Pojo类中？

Question

I have two tables: TABLE_A and TABLE_B, they have some columns with the same names.

TABLE_A (ID, NAME, ADDRESS)<br>
TABLE_B (ID, NAME)

I want to retrieve all columns from both tables and convert the query result to a Pojo class using Jooq, like following:

List<MyPojo> result = query.select()
                         .from(TABLE_A)
                         .join(TABLE_B)
                         .on(TABLE_A.ID.equal(TABLE_B.ID))
                         .fetchInto(MyPojo.class);

I want to use the @Column annotation to specify which column comes from which table, but it seems that Jooq does not support this feature. How can I implements this?

import javax.persistence.Column;

public class MyPojo {

    @Column(table = "TABLE_A", name = "ID")
    private String idA;

    @Column(table = "TABLE_A", name = "NAME")
    private String nameA;

    @Column(table = "TABLE_A", name = "ADDRESS")
    private String addressA;

    @Column(table = "TABLE_B", name = "ID")
    private String idB;

    @Column(table = "TABLE_B", name = "NAME")
    private String nameB;

}

or this,

import javax.persistence.Column;

public class MyPojo {

    @Column(name = "TABLE_A.ID")
    private String idA;

    @Column(name = "TABLE_A.NAME")
    private String nameA;

    @Column(name = "TABLE_A.ADDRESS")
    private String addressA;

    @Column(name = "TABLE_B.ID")
    private String idB;

    @Column(name = "TABLE_B.NAME")
    private String nameB;

}

You could use aliases like so

query.select(
   concat(TABLE_A.NAME).as("Aname")
   ...)
  .from(TABLE_A)
  .join(TABLE_B).on(TABLE_A.ID.equal(TABLE_B.ID))
  .fetchInto(MyPojo.class);

And use Pojo with annotations like

 @Column(name = "Aname")
    private String table_A_name;
