如果AP返回List<****>就报错是什么情况

- 这种直接返回List就报错：
```

@RequestMapping("getAllPermissions")
    public List<NameValueDto<String>> getAllPermissions() {
        return roleService.getAllPermissions();
    }
```

- 这种方法可以：
```

@RequestMapping("getAllPermissions")
    public JsonResult<List<NameValueDto<String>>> getAllPermissions() {
        return JsonResult.success(roleService.getAllPermissions());
    }
```

如果List外面在包裹一层JsonResult倒是可以，但我已经通过拦截器来对返回数据进行包裹，不想在每个方法上去写一次JsonResult包裹了，不知道有没有办法解决这个问题。
- 返回List报错：
