Hello,

Can anyone tell me if it is possible to load a new annotated entity at runtime without restarting of the application?

Eg: I have an annotated class in the core application.

@Entity
class CustomerVersion1
@Id
private Long id;
private String name;
...

The application has started and it is running. In runtime the user has decided to add a new field into the customer entity eg:age

The program generates a new entity(which extends the previous version) CustomerVersion2 and compiles it into class. Then I would like to load this new entity into the system without restart the server.

@Entity
CustomerVersion2 extends CustomerVersion1
private Long age;
...

Is it possible to do it?


Can you offer an annotation based solution where customer can define new fields at runtime into the entity? I would not like to use an entity which keeps the user defined fields in a key value structure.
