java - 如何配置 DBCP PoolableConnectionFactory？

Question

这就是我使用 DBCP 1.4 连接工厂创建数据源的方式:

PoolableConnectionFactory factory = new PoolableConnectionFactory(
  new DriverManagerConnectionFactory("jdbc:h2:mem:db", "", ""),
  new GenericObjectPool(null),
  null,
  "SELECT 1",
  false,
  true
);
DataSource src = new PoolingDataSource(factory.getPool());

工作正常，但我不知道如何使用此处列出的参数配置它:http://commons.apache.org/dbcp/configuration.html .例如，我需要将 testWhileIdle 设置为 true。

Answer 1

    Properties props = new Properties();
    props.put("validationQuery", "SELECT 1 from dual;");
    props.put("testWhileIdle","true");

    final ObjectPool connectionPool = new GenericObjectPool(null);
    final ConnectionFactory connectionFactory = new DriverManagerConnectionFactory(connectUri, props);
    new PoolableConnectionFactory(connectionFactory, connectionPool, null, null, false, true);
    final PoolingDataSource dataSource = new PoolingDataSource(connectionPool);
