测试：

@RequestMapping("/getMoney")
    public String memberWithdrawal(String userName,String pwd,String money) throws Exception {
        UserInfo userInfo = userInfoMapper.queryUserInfoByUserName(userName);
        RequestParamBean param = newRequestParamBean(); 
        //param.set()
        //param.set()
　　　　 String response = httpUtils.doPost("url", JSON.toJSONString(getMoney), userInfo.getCookie()); return response; }
