Error: Java. Lang. Long cannot be cast to Java. Lang. Integer
Long cannot be converted to integer type.
This exception often occurs when querying by hinbernate page.

Cause:

Here, list. Get (0) versions earlier than hibernate2.0 return the integer type.
However, list. Get (0) Versions later than hibernate3.0 return the long type.
Therefore, it cannot be converted from long type to integer type.

Integer is a type that cannot be changed, and long and integer do not have any inheritance relationships. Of course, they cannot be converted like this.
