原因：

传参有问题

解决：

//用户编码
String residentCode = (String)params.get("residentCode");
List<String> residentCodeList=null;
if(!StringUtils.isEmpty(residentCode)){String[] residentCodes = residentCode.split(",");residentCodeList = Arrays.asList(residentCodes);
}
params.put("residentCode",residentCodeList);
