注意swagger的版本，可能需要application.yml配置

mybatisplus的缺点在于 原来的UserMapper的方法重写mybatisplus自带的
postman测试失败 路径没问题，看参数个数。参数对应
但是参数不够容易404 所以解决加默认值

    @GetMapping("/page")
    public IPage<User> findPage(@RequestParam Integer pageNum,
                                @RequestParam Integer pageSize,
                                @RequestParam(defaultValue = "") String username,
                                @RequestParam(defaultValue = "") String nickname,
                                @RequestParam(defaultValue = "") String address){
        IPage<User> page  = new Page<>(pageNum,pageSize);
        QueryWrapper<User> objectQueryWrapper = new QueryWrapper<>();
        objectQueryWrapper.like("username",username);
        objectQueryWrapper.like("nickname",nickname);
        objectQueryWrapper.like("address",address);
        return userService.page(page,objectQueryWrapper);
    }

vue分离需要单独div包括起来 而不是几个独立的标签元素
