I am looking into creating a class in such a way that it can hold references to
itself and a parent. In other words, I am looking to make a bi-directional
tree of these classes.
The class would like something like this:
@Entity
| @Table(name="sample")
| public class Sample {
| private String id;
| private Sample parent;
| private Set<Sample> children;
|
| @Id
| @Column(name="id");
| public String getId(){ return id; }
| public void setId(String id) { this.id=id; }
|
| /** This is where I am confussed.... **/
| }
The proposed table for the above would be:
varchar(256) id
| varchar(256) parentId
I have made plenty of classes that reference one-to-many one way, and
many-to-one the other, but this is the first time I have tried to make these
connections within the same class. I guess I am just getting confused how to
setup the JoinColumn name and the mappedBy in the annotations to work off a
single table column within a single table.
