Hi Together,
I am new to EJB3 and therefore I need your help. Please forgive me if this
question is not very imaginative.
My case:
----------
Let's say I have two tables with different names but with the same structure:
| Team_Green (id, first_name, last_name)
| Team_Blue (id, first_name, last_name)
|
Now I want to use one entity bean (ejb3) for both tables. Like the following
one:
| package ...
|
| import ...
|
| @Entity
| @Table(name="<table_name>")
| public class TeamMember implements Serializable {
|
| private String id;
| private String firstName;
| private String lastName;
|
| public TeamMember() {
| super();
| }
|
| public TeamMember(String id, String firstName, String lastName) {
| super();
| this.id = id;
| this.firstName = firstName;
| this.lastName = lastName
| }
|
| @Id
| @Column(name="id") // I know that this one is not necessary
| public String getId() {
| return id;
| }
| public void setId(String id) {
| this.id = id;
| }
|
| @Column(name="first_name")
| public String getFirstName() {
| return firstName;
| }
| public void setFirstName(String fristName) {
| this.firstName = firstName;
| }
|
| @Column(name="last_name")
| public String getLastName() {
| return lastName;
| }
| public void setLastName(String lastName) {
| this.lastName = lastName;
| }
|
| }
|
My question:
---------------
a:)
How can I set the @Table(name=?...?) at runtime?
Assuming that I know which team member belongs to which team (green or blue):
How can I set the @Table annotation to @Table(name=?Team_Green?) - if the team
member belongs to the green team - or to @Table(name=?Team_Blue?) - it the
person belongs to the blue team.
Is this in any way applicable? And if yes can someone please give me a short
example, tip, hint, etc?
b:)
If a:) is applicable can I do such things with the annotation @Column(name=..)
too?
Thanks for your help in advance.
Regards
