CLOB/BOLB与String互转

 1         String s1="1231dsdgasd的飒飒大";
 2         
 3         Clob c = new SerialClob(s1.toCharArray());//String 转 clob
 4         Blob b = new SerialBlob(s1.getBytes("GBK"));//String 转 blob
 5 //        也可以这样不传字符集名称，默认使用系统的
 6 //        Blob b = new SerialBlob(s1.getBytes());
 7         
 8         String clobString = c.getSubString(1, (int) c.length());//clob 转 String
 9         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()));
12         
13         System.out.println(clobString);
14         System.out.println(blobString);
