Hibernate annotation @ Enumerated

@ Enumerated (value = enumtype. ordinal) interacts with the database using serial numbers of enumeration types,
In this case, the database data type must be numeric, for example, in actual operations
Cattest Ct = new cattest ();
Ct. setcolor (color. Blue );
When we save the object GT to the database, the value stored in the database is blue in the color enumeration.
The serial number 1 in the definition (the serial number starts from scratch );

@ Enumerated (value = enumtype. String) uses the enumeration type to interact with the database,
In this case, the database data type must be nvachar2 or another string type, for example, in actual operations
Cattest Ct = new cattest ();
Ct. setcolor (color. Blue );
The value stored in the database is a blue string.
