Oracle in不超过1000，List<String>参数拆分，代码举例

    public Map<String,Map<String, Object>> getConsInfo(List<String> consIdList) {
        Map<String,Map<String,Object>> retMap = new HashMap<>();
        if(consIdList == null || consIdList.size() == 0){
            return null;
        }

        int len =consIdList.size();
        int cnt = 20;
        for (int i = 0; i <= len/cnt; i++) {
            StringBuilder consIdsBuider = new StringBuilder();
            for (int j = 0; j<cnt && i*cnt+j < len; j++) {
                consIdsBuider.append(",").append(consIdList.get(i*cnt+j));
            }
            String consIds = consIdsBuider.toString().substring(1);
        }

        return retMap;
    }

最近写了一个sql查询in条件的拆分，但是没用到。记下来，避免以后用到的时候重新写
