Class EntityIdPropertyResolver

java.lang.Object

com.mmnaseri.utils.spring.data.domain.impl.id.EntityIdPropertyResolver

All Implemented Interfaces:

IdPropertyResolver

public class EntityIdPropertyResolver
extends Object
implements IdPropertyResolver

This class will use all the magic implemented in the other ID property resolvers to find out the ID property for an entity.

The order in which conditions are considered is:

1. Annotated getter
2. Annotated field
3. Getter for ID property using name
4. Field having proper name

After all the above are considered, if nothing is found, a NoIdPropertyException is thrown to show that the promised ID property was not found on the entity class.
