MemberController

        Map result = new HashMap();
        try {
            Evaluation evaluation = memberService.enjoy(evaluationId);
            result.put("code", "0");
            result.put("msg", "success");
            result.put("evaluation", evaluation);
        } catch (BussinessException e) {
            e.printStackTrace();
            result.put("code", e.getCode());
            result.put("msg", e.getMsg());

你检查一下 你传过来的 请求参数 long类型的值  里面带了逗号没有
