Creates a new BeanWrapper using the given PersistentEntity and ParameterValueProvider. Will instantly create a bean instance using the PreferredConstructor of the PersistentEntity.

Type Parameters:

E -

T -

Parameters:

entity -

provider -

conversionService -

Returns:

setProperty

public void setProperty(PersistentProperty<?> property,
