java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Long in hibernate

Question

I am getting the below exception after migrating hibernate version from 3.x to 5.4.24 ga in my application.

Using db2 database.

Problem is with criteria.list(); -> Tring to cast coSubscrbnSvcStaHstSid value from BIGINT into LONG and throwing the exception.

Based on the column type, sql typdescriptor is selecting and doing the casting to LONG type in hibernate 5 code.

• DB Column type is BIGINT and Hibernate entity column type is long.

How can I avoid this error?. Please help.

Exception is..

for your reference I am attaching the hibernate code here..

@SuppressWarnings({ "unchecked" })
@Override
public <X> X unwrap(Long value, Class<X> type, WrapperOptions options) {
    if ( value == null ) {
        return null;
    }
    if ( Long.class.isAssignableFrom( type ) ) {
        return (X) value;  -> Here is converting from BIGINT to LONG, and breaking.
    }

How can I avoid this error?

You need to change the value of the field in java from Long to BigInteger . You cannot do an easy conversion, because of the reasons outline here .

Does this solve your problem? Let me know in the comments.
