mysql - java.sql.SQLException : Connection is not associated with a managed connection. org.jboss.resource.adapter.jdbc.jdk5.WrappedConnectionJDK5@42d0cb88

Question

我使用jboss5.1和spring作为系统架构。 mysql版本为5.6.12，jdk版本为1.7。 场景:因为我需要更新系统不久前插入数据库的记录，
我尝试在执行插入记录时获取记录的 id。

我使用 GenerateKeyHolder(spring 中的类)来获取 auto id 。来源如下:

    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();

在大多数环境中，代码运行良好，但在一种环境中它会抛出如下异常。太令人惊讶了，我们在测试环境中未能重现该异常。

Answer 1

您收到以下错误消息:

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

并且您使用了jdk 1.7。但没有出现这个问题。

我开始在网络中查找这个问题并发现 this topic 。 WhatDoesTheMessageDoYourOwnHousekeepingMean解释关闭连接对您来说意味着什么。

我认为你需要调整事务超时。@Ellie Fabrero say :有些查询可能需要很长时间，因此超时，hibernate 会抛出异常。
