Examples with PoolingDriver org.apache.commons.dbcp2.PoolingDriver used on opensource projects

Example 1 with PoolingDriver

use of org.apache.commons.dbcp2.PoolingDriver in project logging-log4j2 by apache.

the class PoolingDriverConnectionSource method stop.

@Override

        getLogger().error("Exception stopping connection source for '{}' → '{}'", getConnectionString(), getActualConnectionString(), e);
        return false;
    }
}

Example 2 with PoolingDriver

use of org.apache.commons.dbcp2.PoolingDriver in project logging-log4j2 by apache.

the class PoolingDriverConnectionSource method setupDriver.

    // First, we'll create a ConnectionFactory that the
    // pool will use to create Connections.

    // using the connect string passed in the command line
    // arguments.
    // 
    final Property[] properties = getProperties();

    if (poolableConnectionFactoryConfig != null) {

    }
    // 
    // Now we'll need a ObjectPool that serves as the
    // actual pool of connections.
    // 
    // We'll use a GenericObjectPool instance, although
    // any ObjectPool implementation will suffice.
    // 
    @SuppressWarnings("resource") final ObjectPool<PoolableConnection> // This GenericObjectPool will be closed on shutdown

        driver.registerPool(poolName, connectionPool);
    }
// 
// Now we can just use the connect string "jdbc:apache:commons:dbcp:example"
// to access our pool of Connections.
