I have a Java class with these fields:

@Entity
public class Car {

  @Column(name = "NAME", columnDefinition = "bytea")
  @ColumnTransformer(read = “pgp_sym_decrypt(name, ‘mySecretKey’)”, write = “pgp_sym_encrypt(?, ‘mySecretKey’)”)
  private String name;

  @ManyToMany
  @JoinTable(name = "STUDENT_CAR", 
    joinColumns = @JoinColumn(name = "CAR", referencedColumnName = "NAME", columnDefinition = "bytea"), 
    inverseJoinColumns = @JoinColumn(name = "STUDENT",referencedColumnName="NAME", columnDefinition="bytea"))
  private List<Student> students;

}

I’d like to use the columnTransformer annotation even on the field students with the ManyToMany annotation.
I tried to apply the columnTransformer on that but It doesn’t encrypt/decrypt the columns of the “STUDENT_CAR” table.

Does anyone know another way to make it work?

Thank you all.
