public class DBCPConnectionProvider extends 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)
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

public boolean supportsAggressiveRelease()
This is used in conjunction with 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.
