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。
以下是我正在使用的版本:
Spring 版本: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尝试设置应用程序上下文但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？？
我尝试加载的文件是 queries.xml它位于src/main/resources这是下面的文件:

同样，正常运行项目时一切都运行得很好。仅当我将其作为测试用例运行时，或者当我进入构建的测试部分时，才会出现此错误。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 文件一起使用？
最佳答案
我明白了!!!
我花了几天时间在调试器中单步调试数千行代码，直到能够观察问题的实际情况。事实证明，在 hibernate 深处的类中有一行代码 org.hibernate.boot.registry.classloading.internal.ClassLoaderServiceImpl 它尝试使用以下代码在类路径上找到该文件:
final URL url = getAggregatedClassLoader().getResource( name );
if ( url != null ) {
return url;
}
这里总共有两个问题。首先，尝试解析文件时文件名字符串所遵循的过程不允许删除从 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:，则 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>
而不是:
<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:
