我认为在我的项目中添加一些测试是个好主意，但在这个过程中，我不知何故设法让真正的交易破裂。

我正在使用带有 JPA（休眠）的 Spring MVC。entityManager 无法再正确加载：

跑步时

mvn test

一切都贯穿。在那里我使用嵌入式 H2 数据库删除与测试相关的东西（依赖项等）并没有解决问题。

如果我理解正确的话，Javassist 在这种情况下负责注释。我的问题是我不知道在哪里继续寻找。这真的是UTF8问题吗？为什么它试图扫描/classes目录，同时认为它是一个 jar 文件？

其他可能与该问题相关的列表：

  1. 我在 eclipse 中玩了一下项目配置（为 maven、wst 添加）。我确实再次删除了此配置以尝试是否有所作为。我也曾经mvn package war:war在本地 tomcat 上部署应用程序。同样的错误发生在这里。再次mvn test工作正常

  2. 我将 hibernate-validator 和 hibernate-entitymanager 更新到了最新版本。但是，再次降级仍然存在问题。

定位问题可能需要的其他一些信息：

我的 root-context.xml 的相关部分

<!-- Define transaction Manager -->

我什至无法猜测可能是什么问题。

在这种情况下，当您不知道出了什么问题时，您可以这样做（我希望您的源代码在存储库中（svn/git 等））。

您只需将项目签出/克隆到一个新位置并构建它，看看它是否正常。您有可能没有提交破坏它的更改。

如果问题仍然存在，那么您只需返回旧版本，依此类推，直到您到达最后一个工作版本。然后，您将上一个工作版本与下一个（损坏的）版本进行比较，然后 tada！，您将首先看到导致问题的原因。

在发布这个问题之前尝试了很多事情之后，我实际上只是偶然发现了解决方案：

WEB-INF/classes我从我的文件夹中的测试用例中找到了两个类。这些类实际上是我的测试的配置类。删除它们后，一切都像魅力一样运行。在提取我的战争文件并从我的测试中寻找剩余部分后，我在那里找到了这些类。

为什么会这样？（这只是我的猜测）在 eclipse 中创建一个新的测试文件夹时，我花了一些时间来修改我的 pom.xml 以将此文件夹视为<testSourceDirectory>. Eclipse 在两者之间构建项目，将类文件从我的测试配置类复制到WEB-INF/classes. 这不知何故弄乱了 Spring 和 Hibernate。我的学习：检查只有相关的类被复制到战争文件中，并且 WEB-INF/classes 不包含任何剩余部分。
