    public List<Student> getgood(String str) {
        try {
            List<Student> studentList = memcachedClient.get(str);
            return studentList;
        } catch (TimeoutException | InterruptedException | MemcachedException e) {
            e.printStackTrace();
        }
        return null;
    }
 // 更新学生集合
