Java Spring工具套件应用程序上下文xml错误，即使所有bean似乎都正常工作

我正在一个spring应用上下文XML中配置jpa和jpa存储库

如果我同时拥有

和

，那么Spring工具套件在第1行显示一个错误：

引用的文件包含错误(http://www.springframework.org/schema/context/spring-context-4.0.xsd). 有关详细信息，请右键单击中的消息
查看问题并选择“显示详细信息…”

单击“显示详细信息”后，我得到以下信息：

The errors below were detected when validating the file "spring-context-4.0.xsd" viathe file "app-config.xml".  In most cases these errors can be detected by validating "spring-context-4.0.xsd" directly.  However it is possible that errors will only occur when spring-context-4.0.xsd is validated in the context of app-config.xml.

在

旁边有一条警告说

未找到引用的bean“jpamappingcontext”

运行应用程序时，它似乎工作正常。我可以连接到数据库，并使用JpaRepository接口从数据库中获取数据，因此我不确定为什么STS中会出现致命错误。我假设，由于jpa:repositories和context:component扫描包都使用了这两种扫描包，所以在使用这两种扫描包时会出现一些重复/冲突，但我不确定应该如何解决它（我可能会将服务拆分为它们自己的配置xml，然后在app config中导入，或者将其添加到web.xml中的上下文列表中）

以下是完整的app-config.xml：

以下是完整的app config.xml

这是STS中的一个已知问题：

虽然这个问题已经被宣布关闭，但你可以看到它仍然会弹出

你应该考虑用你的箱子打开一张有春天的JIRA票。

我相信你两次都包括同一个部件。你能保证最多包含一次吗？嗯，我正在对两个不同的包进行包扫描，两个包中都没有重复的类。在DAO包中，我有一个JpaRepository接口，在服务包中，我有一个自动连接DAO的服务接口和实现。消息表明

spring-context-4.0.xsd中有一个错误，重复行号高达488，远高于您的文件长度。您使用的是哪一版本的spring framework和spring jpa？@SergeBallesta 4.0.5.RELEASE。因此，目前，我是否应该忽略这些错误？我能认为它们无害吗？应用程序确实可以工作，但我通常不喜欢应用程序中出现错误。目前，我的“解决方法”是将存储库和服务包扫描仪分离为两个.xml文件，并将它们导入到我的app-config.xml中。这就消除了errors@MrPlow我知道看到红旗潜伏在拐角处很烦人。但只要应用程序运行正常，就应该可以了。你可以再尝试一件事来移除XSD的版本，看看。我会贴一张票，我会玩它，但是就这个帖子来说，我认为我的问题得到了解答。非常感谢。
