Binding child object on submit spring mvc

Question

I\'m newbie in Java so this question looks so simple. I have a model like:

@Entity(name=\"website\")
public class Website {
@Id
@GeneratedValue(strategy=Generati         


        

Answer 1

simply change path in <form:select> tag from publisher to publisher.publisherId

Some more things from my side:

1. You don't need to use @Column(name="websiteId", nullable=false, unique=true)

   • Since You have column name in database same as field name in Entity class
   • Since it is Annotated with @Id it will never null and by default uniqe

2. You don't need to use @JoinColumn at both side, at @OneToMany side use mappedBy attribute e.g. @OneToMany(mappedBy="publisher")
