这是我在 stackoverflow 上的第一个问题，所以如果您遗漏了什么，请提供反馈。

我正在为我的 Web 应用程序使用 JPA (Hibernate 3)、Spring 3.0.6 和 JSF (Icefaces 3.0)。当我使用该应用程序时，我的本地计算机上没有问题。但是如果第二个用户开始四处点击，有时会出现以下异常：

“找到预绑定的 JDBC 连接！如果被告知要管理 DataSource 本身，JpaTransactionManager 不支持在 DataSourceTransactionManager 中运行。建议对单个 DataSource 上的所有事务使用单个 JpaTransactionManager，无论是 JPA 还是 JDBC 访问。”

我的情况这没有意义，因为我只使用一个 JPATransactionManager 和一个 EntityManager（见下面的配置）。唯一应该抛出此异常的情况是在使用多个事务管理器和单个数据源时。

（我认为）由于 JSF，我在会话和事务处理方面遇到了很多问题，并使用此解决方案使其正常工作。

经过一周许多不同的配置和无休止的尝试，我找不到问题的根源。感觉就像我完全错过了配置中的某些东西。

顺便说一句：目前我经常得到例外

“xxxx.xxxx.xxxx 条目中的空 id（发生异常后不要刷新会话）”

在来自完全不同的表的 getAll() 之后。也就是说，堆栈跟踪包含 yyyy.getAll() 并抛出上述异常。我不知道这是从哪里来的。

非常感谢您的帮助！

这是我当前的配置：
