REST API does not support entities with composite primary key #49
Description
Since id of such entities is passed as object it's not possible to call some methods where id is used in path fragment
DELETE /entities/{entityName}/{entityId}
GET /entities/{entityName}/{entityId}
PUT /entities/{entityName}/{entityId}
Solution:
Represent composite key identifier as JSON string and apply base64 URL encoding.
Model:
@Entity(name = "ref$CompositeKeyEntity")
@Table(name = "REF_COMPOSITE_KEY")
public class CompositeKeyEntity extends BaseGenericIdEntity<EntityKey> {
private static final long serialVersionUID = -2538345720324624741L;
@EmbeddedId
private EntityKey id;
@Column(name = "NAME")
private String name;
}
@Embeddable
@MetaClass(name = "ref$EntityKey")
public class EntityKey extends EmbeddableEntity {
@Column(name = "TENANT")
private Integer tenant;
@Column(name = "ENTITY_ID")
private Long entityId;
}
Encoding sample:
- JSON:
{tenant : 1, entityId: 1} - Base 64:

/entities/ref$CompositeKeyEntity/e3RlbmFudCA6IDEsIGVudGl0eUlkOiAxfQ==
