从test / resources注入spring bean无法从main / java中找到类

标签： java spring maven dependency-injection

我在maven项目中使用xml定义了一个spring bean。它在src / main / java中使用pojo类。此xml文件当前存储在src / main / resources中。构建时，一切正常，它作为资源注入。 

   <bean id="test" class="org.testing.framework.model.TestModel">
      values here
   </bean>

但我想将xml文件移动到src / test / resources，但仍然将它从src / main / java引用pojo作为其测试数据。当我将其移动到测试时会抛出错误：

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.testing.framework.model.TestModel]

是否可以将xml spring bean文件移动到test并使用main，如果是这样的话？

由于

的applicationContext.xml

    <import resource="classpath*:TestBeans.xml" />

</beans>

答案 0 :(得分：0)

所以在玩完之后我解决了这个问题。

TestBeans.xml文件放在src / test / resources中名为applicationContext的子文件夹中。

以下行从src / main / resources中的appliationContext.xml中选择bean完全没法

<import resource="classpath*:TestBeans.xml" />

但是这个bean无法访问pojo org.testing.framework.model.TestModel

现在我将导入更改为

<import resource="classpath*:applicationContext/TestBeans.xml" />

它可以像原始线一样拾取豆子，但是bean可以访问pojo。我不清楚为什么它需要文件夹名称，因为文件被正常拾取。它只是无法访问没有文件夹名称的pojo。

有谁知道为什么会这样？无论如何，谢谢你看。
