java - 如何获取 UnexpectedRollbackException 的 SQL 错误来源

Question

我的服务“duplicateContract”出现 hibernate 回滚异常

问题是，我无法调试它，某个地方的持久对象有错误，但我不知道(这不是超时或缺少 @Transactional )。我怎样才能得到这个异常(exception)的更多细节？ (也许在 oracle 日志中的某处？但是在哪里？)。

我检查了 JOTM 源代码，令我惊讶的是，they don't propagate the original exception .

try {
    propagateCtx = false;
    term.commit(true);
    propagateCtx = true;
} catch (TransactionRolledbackException e) {
    Current.getCurrent().forgetTx(getXid());
    if (TraceTm.jta.isDebugEnabled()) {
        TraceTm.jta.debug("Commit distributed transaction -> rolled back!");
    }
    localstatus = Status.STATUS_ROLLEDBACK;
    throw new RollbackException();
} 
...

JOTM项目开发seems to have stopped (最后两个版本可追溯到 2006 年和 2010 年)，因此您最好查看 Narayana , Atomikos或 Bitronix .
