项目构建正常，但为什么JUnit测试失败？

项目构建正常，但是当我运行Junit测试时，我收到“无法加载ApplicationContext”异常。

在JUnit测试中，配置文件的位置如下所示：

 @ContextConfiguration(locations = {"/application-context.xml", "/db-context-test.xml", "/config-context.xml" })

有什么问题？如何找到application-context.xml文件是否正确加载？

3 个答案:

答案 0 :(得分：1)

这是一个类路径问题，一个运行时类路径问题。这就是你可以编译的原因，但是当你运行代码时会出现错误。 As documented here，您需要在类路径中插入一些jar。

答案 1 :(得分：1)

您在运行时缺少com.sun.istack.localization.Localizable。将包含该类的jar添加到类路径中。

答案 2 :(得分：0)

最后，我们通过向pom添加所有必需的类来解决问题

似乎JUnit使用的是与Maven用于构建的不同的JVM，因此如果我在Maven的类路径中有正确的jar文件并不重要。
