无法捕获ConstraintViolationException
我似乎无法捕获约束违规exception，虽然我在日志中看到它。
实体
@Column(unique = true) private String email; 我试图像这样抓住它
try { memberDao.create(newMember); } catch (ConstraintViolationException e) { // }
– 它永远不会到达捕获块。
我用的时候
catch（例外e）
我抓到“javax.transaction.RollbackException：ARJUNA016053：无法提交事务。”
这是错误日志：

我究竟做错了什么 ？
UPDATE >>
我目前的代码是：
try { memberDao.create(newMember); } catch (EJBTransactionRolledbackException e) { log.info("Exception caught!! "+e.getCausedByException()); log.info("Exception caught!! "+e.getCause()); log.info("Exception caught!! "+e.getMessage()); StackTraceElement[] stack = e.getStackTrace(); for (int i = 0; i< stack.length; i++) { log.info(stack[i].toString()); } }
而日志是

它包装在EJBTransactionRolledbackException ，因此您应该尝试捕获那个而不是ConstraintViolationException 。
ConstraintViolationException首先由PersistenceException包装，然后由RollbackException包装，最后由EJBTransactionRolledbackException 。
您应该调用Exception的getCause()方法，直到遇到约束违规或null，这表明该exception不是由于约束违规。 您可以尝试以下方法：
try { memberDao.create(newMember); } catch (EJBTransactionRolledbackException e) { Throwable t = e.getCause(); while ((t != null) && !(t instanceof ConstraintViolationException)) { t = t.getCause(); } if (t instanceof ConstraintViolationException) { // Here you're sure you have a ConstraintViolationException, you can handle it } }
