Druid连接池操作Oracle，Clob与Blob

//操作Oracle数据库的时候，必须要用oracle自带的数据类型，Druid提供了通用方法，效率不错。
if (obj instanceof byte[]){
	com.alibaba.druid.proxy.jdbc.ConnectionProxyImpl cpi = new com.alibaba.druid.proxy.jdbc.ConnectionProxyImpl(dds, cpc,null,(Long)object[0]);
	Blob blob = cpi.createBlob();
	byte[] bin = (byte[])obj;
	blob.setBytes(bin.length, bin);
	ps.setBlob(i+1, blob);
	}
	else
if (obj instanceof char[]){
	Clob clob = new SerialClob((char[])obj);
	com.alibaba.druid.proxy.jdbc.ConnectionProxyImpl cpi = new com.alibaba.druid.proxy.jdbc.ConnectionProxyImpl(dds, cpc,null,(Long)object[0]);
	ClobProxy clobproxy = new ClobProxyImpl(dds,cpi , clob); 
	ps.setClob(i+1, clobproxy.getCharacterStream());
	}
