Hibernate sub-database sub-table

Hibernate sub-database sub-table

transaction is performed on the same database, different databases are more difficult to implement. The transaction

connection is obtained from the database connection pool, and the connection pool will be established according to the relevant parameters at startup.

Session is the encapsulation of JDBC and transactions , the session will be associated with one of the connections, and the session will be associated with a thread, so that the transaction can be completed by the same connection.

The connection pool is managed by the SessionFactory, and the session is generated by the SessionFactory.

Establish different SessionFactory, establish the mapping table of different SessionFactory, so that you can use different SessionFactory to access different databases (different databases have the same table (for the same business and different organizations))

It is easier to divide the data than the table in the code

The way to divide the table is to modify the table name in SQL by AOP.

If data of different functions is placed in different databases, it is necessary to perform database mapping by function to achieve access Different database
