This article is about how Hibernate connection pooling is configured. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

In Hibernate3.0, dbcp is no longer supported. The author of Hibernate clearly points out in Hibernate.org that dbcp has BUG in practice, and in some situations there are a lot of empty connections that cannot be released, so the support for dbcp is abandoned.

1. Hibernate connection pool: C3P0 configuration

Org.Hibernate.transaction.JDBCTransactionFactory 50 false thread true true org.Hibernate.dialect.Oracle9Dialect oracle.jdbc.driver.OracleDriver 0804 0804 jdbc:oracle:thin:@192.168.0.200:1521:orcl 2 2 5000 100 3000 2 false

2. Hibernate connection pool: use proxool

True org.Hibernate.dialect.MySQLDialect pool1 ProxoolConf.xml org.Hibernate.connection.ProxoolConnectionProvider.... ....

The 1.ProxoolConf.xml:xml file is placed in the same level directory and proxool-0.8.3.jar is required.

Pool1 jdbc:mysql://tpdb:3306/tpdb com.mysql.jdbc.Driver 90000 10 10 700 350 900000 14400000 true select sysdate () from dual

two。 The database name can be specified in this way

Jdbc:sqlserver://localhost:1433;DatabaseName=supermarket

3.URL can also pass parameters

Org.gjt.mm.mysql.Driver jdbc:mysql://localhost:3306/struts?useUnicode=true&characterEncoding=GBK

At present, the use of proxool is considered by most people to be a show.

4. Connection pool monitoring

1)。 Add the following paragraph to the web.xml

Proxool org.logicalcobwebs.proxool.admin.servlet.AdminServlet proxool/ Admin/proxool/

2). Http://localhost:8080/testHibernate/Admin/proxool

You can monitor the status of the connection pool!
