I'm using jboss5.1 with spring as the system's architecture. The version of mysql is 5.6.12, and the version of jdk is 1.7. Scenario : Because I need update the record which the system inserted into the DB no long before,
I try to get the id of the record while executing inserting record.

I used GeneratedKeyHolder(class in spring) to get the auto id . The source is as below :

    KeyHolder keyHolder = new GeneratedKeyHolder();
    jdbcTemplate.update(new PreparedStatementCreator()
    {
        public PreparedStatement createPreparedStatement(Connection con) throws SQLException
        {
            PreparedStatement ps = con.prepareStatement(sql, new String[] { "id" });
            ps.setString(1, record.getCmdName());

            ps.setTimestamp(6, new Timestamp(System.currentTimeMillis()));                

            return ps;
        }
    }, keyHolder);        
    return keyHolder.getKey().intValue();

In the most environments, the code work well , but in one environment it throws exception as below. It's so surprising , and we failed to reproduce the exception in our testing environment.

似乎您的“conn”对象未初始化，因此没有有效的连接来执行该语句。

您收到以下错误消息：

Connection is not associated with a managed connection.org.jboss.resource.adapter.jdbc.jdk5.WrappedConnectionJDK5

而你使用jdk 1.7. 但是并没有出现这个问题。

我开始在网上寻找这个问题并找到这个主题。WhatDoesTheMessageDoYourOwnHousekeepingMean解释关闭连接对您意味着什么。

我认为您需要调整事务超时。@Ellie Fabrero说：某些查询可能需要很长时间，因此达到超时并且休眠会引发异常。

我刚刚收到此错误，它看起来与当您没有有效的连接对象时执行查询有关。在我的例子中，我正在遍历一个列表并在列表的每个元素上调用一个插入，但是我的方法是以在调用第二个元素之前清理连接的方式编写的，因此出现了错误。

我想另一种情况是如上所述，连接对象根本没有初始化。

我对这条名为“未分类的 Sql 异常”的奇怪消息有同样的问题。

就我而言，我正在执行选择查询的表中有一些损坏的数据。这就是我们无法在其他环境中重现的原因，包括镜像数据库。

清理数据库表后，这个问题就解决了。
