When I save arabic string, the result in the database MySQL is simply ?.
In the table structure the encoding of the column is UTF-8, there are other arabic data, which means the problem is coming from Hibernate 4.3, when I looked at the documentation Developer Guide there is only one subject related to encoding, UTF, Arabic.., they suggested puting @Nationalized annotation, I did that and it is not useful.
By debugging, the arabic string is still in the object until:
session.saveOrUpdate(myObj);
After that I dont know what happened.
I am developing on Netbeans, thank you for help.
Try to put below line in datasource by specifying useUnicode and characterEncoding.
jdbc:mysql://localhost:3306/dbname?useUnicode=yes&characterEncoding=UTF-8
If you are using spring boot put below line in application.properties file.
spring.datasource.connectionProperties=useUnicode=true;characterEncoding=utf-8;
