Description

Mark Paluch opened DATAMONGO-2554 and commented

Trying to map a property name with prefix/underscore/suffix (e.g. foo_bar) where prefix matches a property results in a MappingException.

Code:

class MyType {
	String foo;
}

Document target = mapper.getMappedObject(
		query(where("foo_hash").is("value")).getQueryObject(),
		context.getPersistentEntity(MyType.class));
org.springframework.data.mapping.MappingException: Couldn't find PersistentEntity for type java.lang.String!

	at org.springframework.data.mongodb.core.convert.QueryMapper.getMappedObject(QueryMapper.java:142)

Ideally, we stop PersistentPropertyPath introspection at types that are considered simple types.
