java - 无法捕获 ConstraintViolationException

Question

尽管我在日志中看到它，但我似乎无法捕捉到它。

实体

@Column(unique = true)
private String email;

我正试图像这样捕获它

try {
        memberDao.create(newMember);
} catch (ConstraintViolationException e) {

    //

}

-- 它永远不会到达 catch block 。

当我使用

捕获(异常 e)

我捕获到“javax.transaction.RollbackException:ARJUNA016053:无法提交事务。”

错误日志如下:

我做错了什么？

更新>>

我当前的代码是:

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());
    }

}

日志是

Answer 1

它包含在 EJBTransactionRolledbackException 中，因此您应该 try catch 该异常而不是 ConstraintViolationException。

ConstraintViolationException 首先被 PersistenceException 包装，然后被 RollbackException 包装，最后被 EJBTransactionRolledbackException 包装>.

您应该调用 Exception 的 getCause() 方法，直到遇到约束违反或 null，这表明异常不是由于约束违反造成的.你可以尝试这样的事情:

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
    }
}
