Spring Controller Advice 没有收到 ConstraintViolationException

Question

controller 抛出 ConstraintViolationException，因为 JPA 实体对字段role进行了模式匹配检查，这是通过 Hibernate 强制执行的。 但是 Controller Advice 将上述异常作为 TransactionSystemException 接收。 目前尚不清楚为什么最初的异常被掩盖了。

@Entity
public class Bar {

    @Pattern(regexp = "^role-.*", message = "Role should conform to naming conventions")
    private String role;
}

抛出的异常

Spring Controller Advice receives TransactionSystemException instead of ConstraintViolationException
