Examples with ObjectPool org.apache.commons.pool2.ObjectPool used on opensource projects

Example 1 with ObjectPool

use of org.apache.commons.pool2.ObjectPool in project spring-framework by spring-projects.

the class CommonsPool2TargetSource method createObjectPool.

/**
	 * Subclasses can override this if they want to return a specific Commons pool.
	 * They should apply any configuration properties to the pool here.
	 * <p>Default is a GenericObjectPool instance with the given pool size.
	 * @return an empty Commons {@code ObjectPool}.
	 * @see GenericObjectPool
	 * @see #setMaxSize
	 */
protected ObjectPool createObjectPool() {
    GenericObjectPoolConfig config = new GenericObjectPoolConfig();
    config.setMaxTotal(getMaxSize());
    config.setMaxIdle(getMaxIdle());
    config.setMinIdle(getMinIdle());
    config.setMaxWaitMillis(getMaxWait());
    config.setTimeBetweenEvictionRunsMillis(getTimeBetweenEvictionRunsMillis());
    config.setMinEvictableIdleTimeMillis(getMinEvictableIdleTimeMillis());
    config.setBlockWhenExhausted(isBlockWhenExhausted());
    return new GenericObjectPool(this, config);
}

Example 2 with ObjectPool

use of org.apache.commons.pool2.ObjectPool in project zeppelin by apache.

the class JDBCInterpreter method createConnectionPool.

private void createConnectionPool(String url, String user, String propertyKey, Properties properties) throws SQLException, ClassNotFoundException {
    ConnectionFactory connectionFactory = new DriverManagerConnectionFactory(url, properties);
    PoolableConnectionFactory poolableConnectionFactory = new PoolableConnectionFactory(connectionFactory, null);
    ObjectPool connectionPool = new GenericObjectPool(poolableConnectionFactory);
    poolableConnectionFactory.setPool(connectionPool);
    Class.forName(properties.getProperty(DRIVER_KEY));
    PoolingDriver driver = new PoolingDriver();
    driver.registerPool(propertyKey + user, connectionPool);
    getJDBCConfiguration(user).saveDBDriverPool(propertyKey, driver);
