Support for dynamic path in QuerydslPredicateBuilder [DATACMNS-1093]

Andrii Ivanenko opened DATACMNS-1093 and commented

In the case when property is declared as Object and for example Map is mostly used, it's not possible to filter against map keys.

private Object value;

When executing query with predicate

Expressions.stringPath("value.key1").eq("val1")

it returns correct results, but when trying to integrate with QuerydslPredicateBuilder there are problems.

In repository I've declared:

bindings.bind(Expressions.stringPath(QData.data.value, "key1")).as("k1").first((path, value) -> path.contains(value));

but exception is thrown in getTargetTypeDescriptor().

It would be great to have possibility at least to override method convertToPropertyPathSpecificType(), so developer can have control over converting values for custom paths

Affects: 1.13.4 (Ingalls SR4)
