Oracle Clob字段取值

 public String ClobToString(CLOB clob) throws SQLException, IOException {

         String reString = "";

         Reader is = clob.getCharacterStream();// 得到流

         BufferedReader br = new BufferedReader(is);

         String s = br.readLine();

         StringBuffer sb = new StringBuffer();

        while (s != null) {// 执行循环将字符串全部取出付值给StringBuffer由StringBuffer转成STRING

             sb.append(s);

             s = br.readLine();

         }

         reString = sb.toString();

        return reString;

     }
