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期望

org.hibernate.exception.ConstraintViolationException

被排除在我的 JUnit 测试之外，而是

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

投掷

javax.validation.ConstraintViolationException

这最终导致奇怪的结果

org.springframework.transaction.TransactionSystemException

我该如何修复它？

代码可在GitHub上找到，第 24 行和第 29 行。

Answer 1

TransactionSystemException#getRootCause如果您对根本原因检查感兴趣并执行任何特定处理，例如，这是预期的行为

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

Answer 2

没有什么需要修复的，一切都按预期进行。

org.hibernate.exception.ConstraintViolationException当违反数据库约束时抛出：

JDBCException 的实现指示请求的 DML 操作导致违反定义的完整性约束。

Hibernate 验证器 5.x是Bean Validation 1.1的实现，因此预计其行为符合规范。
