春季开放 JPA答案

【问题标题】：Spring Open JPA春季开放 JPA
【发布时间】：2009-08-04 18:10:41
【问题描述】：

我正在尝试集成 Spring 和 OpenJpa。对于每种情况，抛出的异常都是 SAXParseException：Prolog 中不允许有任何内容。 我知道该问题可能与 xml 文件有关，但所有相关的 xml 都已正确读取和验证。正确解析了 spring 文件并创建了 bean，但 entitymanager 创建失败，并且根异常是 prolog 错误中不允许此内容。我不确定要在此处发布哪些相关部分。如果需要，我可以发布文件的全部内容。在我向persistence.xml 添加类标记条目后，我进一步隔离了这个问题。谁能帮我解决这个问题？我正在发布完整的堆栈跟踪：

【问题讨论】：

如果您无法弄清楚发生了什么，我建议将此问题发布到 OpenJPA 用户邮件列表/论坛 [1]。 -瑞克 [1] n2.nabble.com/OpenJPA-Users-f208411.html
哪个 JBoss AS 版本？您是否构建或下载了二进制文件？

标签： hibernate spring jpa jboss5.x openjpa

【解决方案1】：

查看源代码和您的堆栈跟踪（查看源代码可以发现很多）似乎是您的 xml 映射文件之一是问题所在。

如果您将 openjpa.MetaData 开启到 TRACE 级别，您将看到它出现在哪个文件中。

我认为您可以通过将 openjpa.Log=openjpa.MetaData=TRACE 指定为属性来做到这一点...虽然我不确定，因为我是通过 spring 而不是普通的 jpa 指定的。

当错误发生时它会告诉你它正在处理什么文件，尽管我怀疑你不会发现任何你可以看到的错误，并且在“prolog”中会有奇怪的字符（你看不到）。

【讨论】：

@Michael Hi 在将 openjpa.MetaData 设置为 TRACE 级别后，我得到了日志，但仍然无法找到问题，因为它没有给出特定的文件名，但通常将类文件夹称为所有的。我已经用更新的错误日志和mapping.xml 更新了我的帖子。你能帮我解决这个问题吗？
听起来你需要添加开放的 jpa 源代码，在调试模式下运行系统并将断点放在靠近它崩溃的地方，这样你就可以看到它在做什么。
我目前正在尝试在调试模式下运行。但奇怪的是，具有相同 xmls 的相同 war 文件在 Websphere 7 中运行良好。但在 JBoss 5 中，这个错误即将到来。现在，当我们在生产环境中使用 Websphere 时，我们在开发人员机器上使用 JBoss。所以它需要在这两种环境下工作。两台服务器有什么不同？
我分担你的痛苦。我们做了同样的事情，在 jboss 上开发，在 WAS 上部署，并且在少数情况下它们的行为不同！在这种情况下，它可能与 jboss 和 websphere 中的类路径/类加载器有关。

【解决方案2】：

好的，所以堆栈跟踪没有指定实际的文件名，但它看起来像 OpenJPA 映射文件之一。

如果在<?xml 声明之前的 xml 文件中有任何内容，通常会引发“Prolog 中不允许内容”异常 - 您需要查看文件并确保不是这种情况。

另一个已知的导致这种情况的可能问题是当 xml 编码被指定为“utf-16”时（某些 XML 工具喜欢这样做）。将其改回“utf-8”往往会解决问题。

【讨论】：

@ChssPly76 我现在没有要发布的 xml 文件，但我已经尝试了这些选项。
所以你是说如果你从persistence.xml中删除一个特定的类条目，一切正常（好吧，类没有被映射，但我这个错误不会发生）？也许那个特定的班级发生了一些奇怪的事情？堆栈跟踪看起来好像存储库正在尝试获取该类的元数据，但无法通过注释来完成，并且正在 /WEB-INF/classes 中寻找 XML 版本...

【解决方案3】：

我最近在 JBoss AS 5 中看到了这一点。问题是某些组件试图通过 VFS（虚拟文件系统）访问 XML 文件，但给出的路径是一个目录。所以应该抛出 FileNotFound 而不是 SAXParser 异常。

检查您的配置，导致 SAXParser 的路径错误。
