Question

我正面临着junit的问题。我试图在我的junit中自动装载数据源，但是在加载上下文文件时，它会抛出错误，指出无法加载应用程序上下文。请查找包含错误跟踪和junit代码的附件。如果你能帮助我，请告诉我。

问题在于xml文件条目。如果任何人都可以提供样本代码，那将会很有帮助。

看起来缺少类名（你只有一个包名）：

<bean id="testDataSource" class="com.jbhunt.apps.freightmanager.test">

这并不能解释您所面临的异常，即抱怨错误的xml。 xml在位置lineNumber：12; columnNumber：10。但是你发布的xml可能不是spring使用的那个吗？在整个项目中搜索名为spring-config.xml的文件，可能有多个文件？

您还可以在DefaultDocumentLoader.java:75上设置断点，而不是您可以看到，spring实际使用了哪个资源。

JUnit for Spring包括创建数据源
