JPA XML 映射文件解析得很好，但在作为 JUnit 测试运行时无法解析答案

【问题标题】：JPA XML Mapping file resolves just fine, but fails to resolve when running as a JUnit testJPA XML 映射文件解析得很好，但在作为 JUnit 测试运行时无法解析
【发布时间】：2016-12-06 01:33:52
【问题描述】：

我有一个带有 XML 设置实体管理器工厂的 spring 项目，其中一部分指向包含我所有查询的外部映射文件。

这是我正在使用的版本：

春季版：4.1.1.RELEASE

JUnit 版本：4.9

Spring-data-jpa 版本：1.7.1.RELEASE

Java 版本：1.8

这里的问题是，在我尝试将 JUnit 测试类添加到我的应用程序之前，我的项目运行良好。事实上，该项目以零错误开始，我可以顺利运行每个查询。现在我已经添加了一个测试类，它失败了，因为在单元测试期间它试图设置应用程序上下文并且无法解析我的映射文件。（从我可以在堆栈跟踪中破译的内容）为什么？？

我要加载的文件是queries.xml，它位于src/main/resources，下面是文件：

我有一个用于主应用程序的上下文文件和一个用于 JUnit 测试的上下文文件，它们完全相同。以下是我的上下文文件的副本：

一切似乎都运行良好！ ..除了我现在不能使用我的查询，所以这并不能解决我的问题。

这是我尝试运行时得到的堆栈跟踪：

同样，正常运行项目时一切运行良好。只有当我将它作为测试用例运行时，或者当我进入构建的测试部分时，我才会收到此错误。这里发生了什么？在单元测试期间如何让它与我的外部 query.xml 文件一起工作？

【解决方案1】：

我想通了！！！！

我花了几天时间在调试器中单步执行数千行代码，直到我能够观察问题的实际情况。事实证明，hibernate org.hibernate.boot.registry.classloading.internal.ClassLoaderServiceImpl 深处的类中有一行代码，它尝试使用以下代码在类路径中定位文件：

final URL url = getAggregatedClassLoader().getResource( name );
        if ( url != null ) {
            return url;
        }

这里总共有两个问题。首先，在尝试解析文件时文件名字符串所遵循的过程不允许剥离从queries.xml 文件复制的换行符和空格。最后一个问题是，如果您在生产期间不附加 classpath:，getResource() 返回 null，但如果您在作为 JUnit 运行时附加 classpath:，则返回 null。我不知道为什么会发生这种情况，但确实如此。因此，我的解决方案是修改用于 JUnit 测试的上下文文件以使用：

<beans:property name="mappingResources">
        <beans:list>
            <beans:value>queries.xml</beans:value>
        </beans:list>
    </beans:property>

代替：

<beans:property name="mappingResources">
        <beans:list>
            <beans:value>
                classpath:queries.xml
            </beans:value>
        </beans:list>
    </beans:property>

因此，我最终得到了修改后的测试应用程序上下文，如下所示：
