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，但我不知道如何配置它，这里列出的参数：http: //commons.apache.org/dbcp/configuration.html。例如，我需要设置testWhileIdle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);

Answer 2

BasicDataSource 有这些属性，你可以切换使用吗？

BasicDataSource ds = new BasicDataSource();
ds.setDriverClassName(JDBCDriver);
ds.setUrl(JDBCUrl);
ds.setUsername(JDBCUser);
ds.setPassword(JDBCPassword);
ds.setInitialSize(initSize);
ds.setTestOnBorrow(false);
ds.setTestWhileIdle(true);
