int rs=0;

try {

String IDid=data.get("ID")==null?"":data.get("ID").toString();

String account=data.get("account")==null?"":data.get("account").toString();

if(IDid.length()==0) {

return faileResultMap("参数：ID不能为空");

}else if(account.length()==0) {

return faileResultMap("参数：用户账号不能为空");

}else {

List<String> IDlist=new ArrayList<String>();

String[] strs=IDid.split(",");

for(int i=0,len=strs.length;i<len;i++){

IDlist.add(strs[i].toString());

}

rs=barcodeScanMapper.chooseconfirm(account,IDlist);
