JAR中的Spring依赖项注入

我有项目A中的dao层，项目B是使用项目A作为其依赖的应用层

我可以看到项目A中的类，并在项目B中使用这些类进行了完美的编码。

现在我想做JUnit测试

在(MyTest.java)中

@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
@ContextConfiguration(locations = { "classpath*:reb/spring/persistenceContextTest.xml", "classpath*:rev/spring/modelContextTest.xml" })
public class MyTest extends AbstractTransactionalJUnit4SpringContextTests {
@Autowired
protected HibernateTemplate hibernateTemplate;
@Autowired
protected DAOImpl dao;
//CODE here
}

这里一切都很好。所有属性都已正确注入，没有任何问题。

现在我需要测试应用层｛项目b｝

@ContextConfiguration(locations = { "classpath*:reb/spring/applicationContextTest.xml" })
public class MyAnotherTest extends AbstractTransactionalJUnit4SpringContextTests {
@Autowired
protected HibernateTemplate hibernateTemplate;
@Autowired
protected DAOImpl dao;
}

和applicationContextTest.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://cxf.apache.org/jaxws 
http://cxf.apache.org/schemas/jaxws.xsd">
<import resource="classpath:META-INF/cxf/cxf.xml" />
<import resource="classpath:META-INF/cxf/cxf-extension-soap.xml" />
<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<import resource="classpath*:reb/spring/persistenceContextTest.xml" />
<import resource="classpath*:reb/spring/modelContextTest.xml" />
</beans>

但是当我运行B测试时，Spring无法找到项目A中定义的属性。我该如何做到这一点？

更新我将测试xml移到了Src文件夹中，以便maven在项目B中识别，而且它确实识别了。然而，我得到以下错误仍然

如果您使用maven，则src/test中的任何资源和源都是单个模块的本地资源和源，即projectA/src/test中的任何内容都将对projectB隐藏。有多种选择：

移动测试资源：我不鼓励您这样做，但基本上您可以将applicationContextTest.xml移动到src/main文件夹，但在二进制可交付成果中有测试代码。
复制测试资源：当您将任何bean设置从projectA复制到projectB时，这并不像前面的建议那么糟糕。这通常意味着您正在为单元测试创建测试应用程序上下文，并且您的实际应用程序有不同的应用程序上下文。
删除所有测试应用程序上下文：这将是最干净的解决方案，如果你没有任何测试上下文，你将被迫测试真实的东西如果您需要特定于环境的属性，可以使用PropertyPlaceHolders，如果您需要不同的bean(连接池等)，可以使用Profiles。

看看新的Spring3.1配置文件功能：http://blog.springsource.org/2011/02/14/spring-3-1-m1-introducing-profile/

您的测试持久性上下文xml名称在项目A和项目B中相同。您能否尝试将项目A中的名称persistenceContextTest.xml更改为persistenceContextTestA.xml，以确保问题不是因为文件名重复。
