Class DBCPConnectionProvider  

java.lang.Object
  com.xpn.xwiki.store.DBCPConnectionProvider

All Implemented Interfaces:

org.hibernate.connection.ConnectionProvider

---

public class DBCPConnectionProvider

extends java.lang.Object

implements org.hibernate.connection.ConnectionProvider

A connection provider that uses an Apache commons DBCP connection pool.

To use this connection provider set:
hibernate.connection.provider_class org.hibernate.connection.DBCPConnectionProvider

Supported Hibernate properties:
   hibernate.connection.driver_class
   hibernate.connection.url
   hibernate.connection.username
   hibernate.connection.password
   hibernate.connection.isolation
   hibernate.connection.autocommit
   hibernate.connection.pool_size
   hibernate.connection (JDBC driver properties)

All DBCP properties are also supported by using the hibernate.dbcp prefix. A complete list can be found on the DBCP configuration page: http://jakarta.apache.org/commons/dbcp/configuration.html.

Example:
   hibernate.connection.provider_class org.hibernate.connection.DBCPConnectionProvider
   hibernate.connection.driver_class org.hsqldb.jdbcDriver
   hibernate.connection.username sa
   hibernate.connection.password
   hibernate.connection.url jdbc:hsqldb:test
   hibernate.connection.pool_size 20
   hibernate.dbcp.initialSize 10
   hibernate.dbcp.maxWait 3000
   hibernate.dbcp.validationQuery select 1 from dual

More information about configuring/using DBCP can be found on the DBCP website. There you will also find the DBCP wiki, mailing lists, issue tracking and other support facilities

Method Detail

configure

public void configure(java.util.Properties props)
               throws org.hibernate.HibernateException

Description copied from interface: org.hibernate.connection.ConnectionProvider

Initialize the connection provider from given properties.

Specified by:

configure in interface org.hibernate.connection.ConnectionProvider

---

getConnection

public java.sql.Connection getConnection()
                                  throws java.sql.SQLException

Description copied from interface: org.hibernate.connection.ConnectionProvider

Grab a connection

Specified by:

getConnection in interface org.hibernate.connection.ConnectionProvider

---

closeConnection

public void closeConnection(java.sql.Connection conn)
                     throws java.sql.SQLException

Description copied from interface: org.hibernate.connection.ConnectionProvider

Dispose of a used connection.

Specified by:

closeConnection in interface org.hibernate.connection.ConnectionProvider

---

close

public void close()
           throws org.hibernate.HibernateException

Description copied from interface: org.hibernate.connection.ConnectionProvider

Release all resources held by this provider. JavaDoc requires a second sentence.

Specified by:

close in interface org.hibernate.connection.ConnectionProvider

---

supportsAggressiveRelease

public boolean supportsAggressiveRelease()

Does this connection provider support aggressive release of JDBC connections and re-acquistion of those connections (if need be) later?

This is used in conjunction with org.hibernate.cfg.Environment.RELEASE_CONNECTIONS to aggressively release JDBC connections. However, the configured ConnectionProvider must support re-acquisition of the same underlying connection for that semantic to work.

Typically, this is only true in managed environments where a container tracks connections by transaction or thread.

Specified by:

supportsAggressiveRelease in interface org.hibernate.connection.ConnectionProvider

logStatistics

protected void logStatistics()
