春天的JUnit不会从XML

Question

加载整个的applicationContext我已经与下一个代码春天创建一个JUnit测试：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = { 
    "classpath:*/WEB-INF/demo-servlet.xml"}) 
public class CrudTestJUnit extends AbstractJUnit4SpringContextTests { 

    @Autowired 
    protected ShoppingCartDao shoppingCartDao; 

    @Autowired 
    private ApplicationContext context; 

    @Before 
    public void setUp(){ 

    } 

    @Test 
    public void testSomething() { 
     System.out.println("Evo beanvoa:" + Arrays.toString(context.getBeanDefinitionNames())); 
     Assert.assertTrue(false); 
    } 
} 

在演示servlet.xml中，我定义的bean：

<bean id="shoppingCartDao" class="com.it355.hibernatecrud.dao.impl.ShoppingCartDaoImpl"></bean> 

当我运行JUnit测试我得到这个错误：

Error creating bean with name 'CrudTestJUnit': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: protected com.it355.hibernatecrud.dao.ShoppingCartDao CrudTestJUnit.shoppingCartDao; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.it355.hibernatecrud.dao.ShoppingCartDao] found for dependency: 

当我删除的购物车我得到这个从getBeanDefinitionNames（）：

Evo beanvoa:[org.springframework.context.annotation.internalConfigurationAnnotationProcessor, 
org.springframework.context.annotation.internalAutowiredAnnotationProcessor, 
org.springframework.context.annotation.internalRequiredAnnotationProcessor, 
org.springframework.context.annotation.internalCommonAnnotationProcessor, 
org.springframework.context.annotation.internalPersistenceAnnotationProcessor, 
org.springframework.context.event.internalEventListenerProcessor, 
org.springframework.context.event.internalEventListenerFactory, 
org.springframework.context.annotation.ConfigurationClassPostProcessor.importAwareProcessor, org.springframework.context.annotation.ConfigurationClassPostProcessor.enhancedConfigurationProcessor] 

这里是我的全部演示servlet.xml文件：

    </bean> 

</beans> 

我错在调用配置文件或一些其他的事情吗？有没有人遇到同样的问题？

另外在我的配置文件中，我配置了组件扫描，并且我的应用程序工作并加载了没有任何问题的bean，但是JUnit出现了问题。

Answer 1

在最后，我发现了从WEB-INF该配置必须加载这样的：

@ContextConfiguration(locations = { "file:src/main/webapp/WEB-INF/demo-servlet.xml"}) 

Answer 2

看来你的XML配置文件无法找到或正确加载，因此你不能够正确进行注射。

我建议只使用classpath，如果您的XML配置文件在您的CLASSPATH中，则不需要提及WEB-INF等。像这样：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration("classpath:demo-servlet.xml") 
public class CrudTestJUnit extends AbstractJUnit4SpringContextTests { 
}
