java.lang.ClassCastException: com.alibaba.druid.pool.DruidPooledConnection cannot be cast to oracle.jdbc.OracleConnection
	at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:105)
	at oracle.sql.ArrayDescriptor.createDescriptor(ArrayDescriptor.java:73)

失败原因：

The connection pool usually has a wrapper around the real connection instance, that‘s why your cast fails.

连接池通常包装了一个真实的真实的Connection实例。

解决方案：

Connection connection = ...; // Oracle

// 增加此代码，将Connection转换为OracleConnection
connection = connection.unwrap(OracleConnection.class);

StructDescriptor st = new StructDescriptor("T_ORDER", connection);
