I have two custom datatypes: A and B where B extends A.
Also I do have AAttributeConverter for A and BAttributeConverter for B (both with @Converter(autoApply = true)).
This scenario works fine with hibernate 5.0.9.Final.
However, when I update to recent 5.2.8.Final I get this error:
{code}
Caused by: java.lang.RuntimeException: Multiple auto-apply converters matched attribute [com.example.MyBean.value] : com.example.AAttributeConverter, com.example.BAttributeConverter
at org.hibernate.boot.internal.AttributeConverterManager.findAutoApplyConverterForAttribute(AttributeConverterManager.java:93)
at org.hibernate.cfg.AbstractPropertyHolder.resolveAttributeConverterDescriptor(AbstractPropertyHolder.java:96)
...
{code}
The property MyBean.value has type B that extends A. As BAttributeConverter is more specific and AAttributeConverter can not actually handle B hibernate should IMHO not consider AAttributeConverter here. |
