基于Spring,CLOB/BLOB/String互转

        String s1="Holle world!";
         
        Clob c = new SerialClob(s1.toCharArray());//String 转 clob
        Blob b = new SerialBlob(s1.getBytes("GBK"));//String 转 blob
        //      也可以不传字符集名称,那么默认使用系统的
        //      Blob b = new SerialBlob(s1.getBytes());
         
        String clobString = c.getSubString(1, (int) c.length());//clob 转 String
        String blobString = new String(b.getBytes(1, (int) b.length()),"GBK");//blob 转 String
        //      前面若没传入字符集名称，则这里也不需要传入，以免出错
        //      String blobString = new String(b.getBytes(1, (int) b.length()));
