CLOB/BLOB互转

  String s1="1231dsdgasd的飒飒大";

02

03	Clob c = new SerialClob(s1.toCharArray());//String 转 clob

04	Blob b = new SerialBlob(s1.getBytes("GBK"));//String 转 blob

05	//      也可以这样不传字符集名称，默认使用系统的

06	//      Blob b = new SerialBlob(s1.getBytes());

07

08	String clobString = c.getSubString(1, (int) c.length());//clob 转 String

09	String blobString = new String(b.getBytes(1, (int) b.length()),"GBK");//blob 转 String

10	//      前面若没传入字符集名称，则这里也不需要传入，以免出错

11	//      String blobString = new String(b.getBytes(1, (int) b.length()));

13	System.out.println(clobString);

14	System.out.println(blobString);
