错误：构建休眠SessionFactory

我的堆栈跟踪太长，无法全部粘贴，但我会粘贴它的“最可疑”部分。这也是堆栈跟踪的最后一部分。可疑的是，hibernate正在寻找名为“id”的属性，并且该属性不存在。我从数据库中删除了该属性，并在修改了表格后从数据库映射中生成了User类。我的代码之前工作，但我无法恢复，我不知道哪个行动打破了代码。错误：构建休眠SessionFactory

你有“的getId”任何的Java bean的getter需要由二传手陪同，一些JPA提供商... –

这是解决方案，非常感谢你。但是这个方法是从接口继承的，我假设hibernate会检查“get”关键字或类似的东西。 – Spasoje

堆栈跟踪显示你的缺失为id字段

所致二传手：组织。 hibernate.PropertyNotFoundException：无法找到属性设置方法[com.event.domain.User＃id]

你需要添加

public void setId(String id){ 
this.id = id; 
}
