java - Spring TransactionSystemException 中的 Hibernate 验证结果

Question

我正在使用 Spring 4.3.3、Spring Data 1.10.5、Hibernate 5.0.11 和 Hibernate Validator 5.3.1。

问题是当验证失败时我会期望

org.hibernate.exception.ConstraintViolationException

被扔出我的 JUnit 测试，而是

org.hibernate.cfg.beanvalidation.BeanValidationEventListener.validate(BeanValidationEventListener.java:138)

抛出

javax.validation.ConstraintViolationException

最终导致奇怪的结果

org.springframework.transaction.TransactionSystemException

我该如何解决？

代码位于 GitHub , 第 24 和 29 行。

如果您对根本原因感兴趣，请检查 TransactionSystemException#getRootCause 并执行任何特定处理，例如

@ExceptionHandler(TransactionSystemException.class)
public String handleConstrainException(TransactionSystemException ex) {
    if (ex.getRootCause() instanceof ConstraintViolationException) {
        ConstraintViolationException constraintViolationException = (ConstraintViolationException) ex.getRootCause();
    }
}
