示例 Struts2 spring4.1 jpa/hibernate3.1.6 中的 java.lang.reflect.InvocationTargetException

【中文标题】示例 Struts2 spring4.1 jpa/hibernate3.1.6 中的 java.lang.reflect.InvocationTargetException【英文标题】：java.lang.reflect.InvocationTargetException in sample Struts2 spring4.1 jpa/hibernate3.1.6 【发布时间】：2014-12-01 18:05:09 【问题描述】：

我正在尝试开发一个具有教学目的的基本应用程序，使用 Struts 2 + Spring 4.1 + JPA / Hibernate 3.6 和 Netbeans 8 作为 IDE。我设法毫无问题地创建和更新用户，但是当我尝试登录时，我得到java.lang.reflect.InvocationTargetException，特别是在此说明中：

Query query = entityManager.createQuery(
           "from User where username = :username")
           .setParameter("username", username);

数据库已创建并在每个表中包含几条记录。

对于我为什么会发生这种情况，我将不胜感激。

这是我正在使用的库的列表：

【问题讨论】：

java.lang.reflect.InvocationTargetException 表示在真正的异常之上有一个额外的层。您需要向下滚动堆栈跟踪，复制（全部）Caused By foo.bar.SomeException 并通过编辑将它们放入您的问题中 您将一半的代码库转储给我们，但忘记了最重要的，实际的堆栈跟踪...... 不相关，但您是否真的同时使用 S2 和 Spring MVC？门户网站？ 抱歉，我不得不删除一些文件，但已经删除了 Stacktrace。我正在为我的 POJO 的 DI 使用 spring 并简化休眠集成，这做得不好？库不正确？ - 感谢您的快速回答 它们并非设计不佳，但可能不适用于您的设计不佳应用程序。 【参考方案1】：

解决了

感谢所有用户的 cmets。
