Question

在我的spring-boot maven项目中，其中一个依赖项是spring-data-commons。它扫描我的项目中的类并抛出StackOverflow错误。它不喜欢的课程如下，

class TreeNode<T> {
    private T someData = null;
    private List<TreeNode<T>> children = new ArrayList<>();
}

我认为它正在对字段尝试一些反射机制，然后由于某些不确定的循环而失败。在spring-boot应用程序启动期间记录日志。

我不希望它扫描这个类（或任何类）。我只是删除spring-data-commons并不成功。因为它在我的应用程序的其他部分中用于注入一些会话对象。

有什么建议可以解决这个问题吗？

P.S：我不是弹簧数据方面的专家。但是已经使用弹簧已经有一段时间了。

干杯！
