I have recently tried Hibernate in a project. Because the project is divided into two parts, in another part, a connection pool (self-developed) has been used. Now two parts should be combined, so there is a problem. Start, we decided to use Hibernate's external connection method for data access:
Java code:
1
2
public
Static DBSession OpenSession
(
)
{
...}
3 dBSession dbssion =
NULL;
4
Try
{
...}
5
//System.out.println ("Session is start ");
6 ConnectionPool ConnectionPool = PooledConnectionFactory.
GetConnectionPool
(
);
Seduce
Connection con = ConnectionPool.
GetConnection
(
);
8
9 session s =
(Session
Sense.
get
(
);
10
IF
(s ==
NULL
)
{
...}
11 s = fact.
OpenSession
(Con
);
// Here, use the connection given by the external connection pool
12 session.
set
(s)
);
13
}
14
15 dBSession =
New dbssion
(s)
);
16
}
Catch
(
Throwable T
)
{
In one
String msg = "COULDN
'T Open a hibernate session for sessionFactory' " "
'"; 18 log.error (MSG, T); 19 throw new dbexception (msg ": " TgetMessage ()); 20} 21 Return DBSession; 22} 23
The session method is turned off as follows:
Java code:
1
2
public
Static
Void CloseSession
(
)
Throws HibernateException,
EXCEPTION
{
...}
3 session s =
(Session
Sense.
get
(
);
4 session.
set
(
NULL
);
5
IF
(s! =
NULL
)
{
...}
6 s.
Connection
(
).
Close
(
);
7 s.
Close
(
);
8
SYSTEM.
OUT.
PRINTLN
("session closing"
);
9
// s = NULL;
10
11
}
12
}
13
