如何设置spring上下文：Component-Scan扫描单元测试环境中的“src/main/java”而不是“src/test.java”

Question

我对spring和Maven是新手。最近，我构建了spring MVC项目，并使用maven管理项目结构和依赖关系。

在编写单元测试时，遇到了一个问题，就是无法从“src/main/java”获取bean，而上下文似乎只能从“src/test/java”加载bean。

单元测试：src/test/java/com/web/component/form

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:META-INF/spring/applicationContext-web-test.xml"})
public class FormTest { 
    @Autowired
    private BeanFactory beanFactory; // I override this bean by myself
}

配置XML文件：src/test/resources/meta-inf/spring/applicationcontext-web-test.XML下面的组件扫描似乎只扫描src/test/java中定义的bean，而不是src/main/java。

<context:component-scan base-package="com.web">
    <context:exclude-filter expression=".*_Roo_.*" type="regex"/>
    <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation"/>
</context:component-scan>

重写BeanFactory类在src/main/java/com/web/helper/中。

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.web.helper.BeanFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:924)
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:793)

    at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:478)

所以，我想问一下，有没有一种方法可以改变组件扫描，让它扫描src/main/java中定义的bean/类，而不是spring maven单元测试中的src/test/java？

若要获得BeanFactor，可以实现BeanFactoryAware
