Spring Dependency Injection from JAR

Question

I have dao layer which is in project A and project B is application layer which uses project A as it's dependency

I can see the classes from project A and coded perfectly in project B using those classes.

Now I want to do JUnit testing

in A (MyTest.java)

@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
}

Everything is fine here. All properties are injected properly and no issues.

Now I need to test Application Layer {project b}

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

and in 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>

but when I run the B test, Spring is unable to find the properties defined in project A. How do i achieve this?

Update I moved test xmls to Src folder so that maven recognize in Project B and indeed it recognized. however I am getting below error still

Answer 1

if you are using maven, then any resources and sources in src/test are local the individual module, ie anything in projectA/src/test will be hidden from projectB . There are multiple options available:

• Move Test Resources: I would discourage you from doing this, but basically you can move your applicationContextTest.xml to the src/main folder, but then you have test code in your binary deliverables.

• Replicate Test Resources: This is not as bad as the previous suggestion, when you copy any bean setup from projectA to projectB . This usually implies that you are creating test application contexts for your unit tests and that you have different application contexts for your real application.

• Delete all Test Application Contexts: This would be the cleanest solution, if you dont have any test context you are forced to test the real thing. If you need environment specific properties you can use PropertyPlaceHolders, if you need different beans (Connection Pools, etc.) you can use Profiles.

Have a look at the new Spring 3.1 Feature for Profiles: http://blog.springsource.org/2011/02/14/spring-3-1-m1-introducing-profile/

Answer 2

您的测试持久性上下文xml名称在项目A和项目B中是相同的。您是否可以尝试将项目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。
