exception - 事务被回滚，当执行大量查询时(JBoss 5.1)

Question

我在执行大量查询时遇到问题。

我需要在单个事务中执行超过 10, 000 个 native sql 查询。这些查询是动态生成的，并缓存在系统中。查询生成完成后，这些查询将在单个事务中一个接一个地发送和执行。该应用程序使用 EJB 3 开发并在 JBoss 5.1 上运行。

如果查询数量少于 7200(近似值)，应用程序可以正常工作。但是如果有比这更多的查询，该方法将抛出 EJB 异常并且事务被回滚。没有数据被持久化。

这是回滚发生的地方。 [仅当查询数量超过 7200 时]

 @TransactionAttribute(TransactionAttributeType.REQUIRED)
 public void confirmOrder(String[] queries) {
    for (int i = 0; i < queries.length; i++) {
        em.createNativeQuery(queries[i]).executeUpdate();        //line # 108
    }
    BigInteger bigInt = (BigInteger)em.createNativeQuery("select max(id) from order_item").getSingleResult();
    return bigInt!=null ? Long.valueOf(bigInt.longValue()) : null;
}

有没有办法增加可以在事务中执行的查询数量？请对此提出您的建议。

您可以根据需要在全局或方法级别增加事务超时。

• 如果你想在方法级别做，下面的注解可以用过的。 (超时设置为 1500 秒)@TransactionTimeout(1500)
• 如果您想在全局范围内执行此操作，则必须编辑位于 [server-instance]/deploy 目录中的 transaction-jboss-beans.xml 并更改超时参数值。例如:超时值为 1200 秒

  < property name="transactionTimeout"> 1200 < /property >
