将clob数据类型转化为String类型（在json字符串赋值时候）

1 public  String ClobToString(Clob clob) throws SQLException, IOException {
2
3         String reString = "";
4         Reader is = clob.getCharacterStream();// 得到流
5         BufferedReader br = new BufferedReader(is);
6         String s = br.readLine();
7         StringBuffer sb = new StringBuffer();
8         while (s != null) {// 执行循环将字符串全部取出付值给 StringBuffer由StringBuffer转成STRING
9         sb.append(s);
10         s = br.readLine();
11         }
12         reString = sb.toString();
13         return reString;
14         }
