The mapping file for hibernate when using the Oracle database and the MySQL database. Different hbm.xml

If you are using an Oracle database, then hibernate's mapping file. Hbm.xml is as follows:

<id name= "Xuehao" column= "Xuehao" >

</id>

This ID is not generated automatically by the database, which needs to be noted, and the fields must correspond to the entity class, and the corresponding get () method and set () method are also required in the entity class.

Because the IDs in the Oracle database are automatically generated, there is no need to write the ID of the database, which is very different from the MySQL database, and the MySQL database must specify the ID when the table is built, while Oracle does not, when inserted, Both MySQL and Oracle databases can be used without specifying an ID.
