}

MemberServiceImpl.java 实现类
//通过手机号查询身份证号

    public Map queryIdcard(Map<String, String> inMap) throws Exception{
        List list = dao.queryForList("wt_userlogin.queryInfoByUserName", inMap);
        Map outMap = new HashMap();
        if(list.size()==1){
            outMap.putAll((Map)list.get(0));
            outMap.put("code","1");
        }else {
            if(list.size()<1){
                outMap.put("msg", "该手机号未注册，请注册后再进行登录");
            }else{
                outMap.put("msg", "该手机号对应"+list.size()+"条用户信息");
            }
            outMap.put("code", "-1");
        }
        return outMap;
    }
