问题场景：

        从Oracle读取出来的字段是Clob类型数据，因需要对其进行操作，则转成字符串类型

调用方法：

Clob clobDDL = (Clob) map.get("ClobDDL");
String str = ClobToString(clobDDL);

转化方法：

    /*** clob转String** @param clob* @return*/public String ClobToString(Clob clob) {String reString = "";try {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STRINGsb.append(s);s = br.readLine();}reString = sb.toString();} catch (Exception e) {log.error("Oracle数据由Clob类型转化String类型处理失败 原因={}", e.getMessage());throw new BizException("Oracle数据处理失败");}return reString;}
