【Java】clob 转换 String

从Oracle取出的字段类型有CLOB类型，转换成json会报错。

直接加上这段代码就行： 

if(null != list && list.size() > 0){ // clob 转换 String
            for (int i = 0; i < list.size(); i++){
                Map<String, Object> news = (Map<String, Object>) list.get(i);
                Clob clob = (Clob) news.get("PARKDESCRIPTION");//clob类型字段
                String content = "";
                if (clob != null) {
                    content = ClobUtil.ClobToString(clob).replace("&ldquo;", "\"").replace("&rdquo;", "\"");
                }
                news.put("PARKDESCRIPTION", content);//替换
            }
        }
