hibernate - 什么会导致Hibernate InvalidStateException

Question

即使模型类中没有验证约束，我也会收到此错误（所有成员变量均已正确设置，但我在创建对象时仍然遇到此异常）。如何调试此错误？

Answer 1

每个InvalidStateException都有一个InvalidValue数组。每个InvalidValue都会显示您要保留的bean的哪个属性被违反。正如@Arthur正确指出的那样，违反Java持久性注释的情况也以InvalidStateException结尾。

为了调试您的问题，我将在InvalidStateException中临时捕获com.mycompany.action.UserHome.persist并按如下所示打印每个InvalidValue：

} catch (InvalidStateException e) {
    for (InvalidValue invalidValue : e.getInvalidValues()) {
        log.info("Instance of bean class: " + invalidValue.getBeanClass().getSimpleName() +
                 " has an invalid property: " + invalidValue.getPropertyName() +
                 " with message: " + invalidValue.getMessage()));
    }
}
