在Eclipse中爲Maven項目運行JUnit測試用例

Question

我使用maven eclipse插件（m2e）導入了Maven項目，一切正常。 但是當我運行JUnit測試的情況下，我得到下面的錯誤

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'be.belgacom.rosy.betty.manager.impl.ReservationManagerImplTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests.setDataSource(javax.sql.DataSource); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [javax.sql.DataSource] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我相信你可能會建議看屬性和其它XML文件的配置是否正確。 如果我將相同的項目導入到Eclipse中作爲正常項目，我可以運行JUnit測試。 當我作爲Maven項目導入時，會出現這樣的錯誤。

任何想法，我該如何解決這個問題。

Answer 1

你的問題缺乏很多上下文。你有沒有從Maven的命令行運行它？例如，你是否在命令行上運行「mvn test」？先試試這個，然後讓我們知道你是否收到相同的錯誤信息。

您的問題表明您的POM不包含適當的依賴關係。
