CLOB/BLOB与String互转

CLOB/BLOB与String互转。

??String s1="1231dsdgasd的飒飒大";
??
??Clob c = new SerialClob(s1.toCharArray());//String 转 clob
??Blob b = new SerialBlob(s1.getBytes("GBK"));//String 转 blob
//??也可以这样不传字符集名称，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()));
??
??System.out.println(clobString);
??System.out.println(blobString);
