java将clob类型装换clob转换成字符串clob装换成int

public static String ClobToString(Clob sc) throws SQLException, IOException {  
        String reString = "";  
        Reader is = sc.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;  
    }
