java Clob 问题解决

public String ClobToString(Object message) throws SQLException, IOException {

        String reString = "";
        Reader is = ((Clob) message).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;
    }
