没有休眠验证器，我的应用程序可以正常工作，但是当我将其包含在项目中时，我会收到该错误

我没有要做什么。请帮忙，对不起我的英语

最佳答案

看来您的hashCode（）抛出NullPointerException：

java.lang.NullPointerException
com.springapp.model.User.hashCode(User.java:133)

如果我不得不猜测，问题可能出在这里：

result = prime * result + ((ssoId == null) ? 0 : ssoId.hashCode());

您应该检查您的ssoId。确保它具有您拥有的每个字段的所有获取器和设置器。
