JAR的Spring依賴注入

Question

我有項目A中的dao層，項目B是使用項目A作為依賴項的應用層

我可以看到項目A中的類，並使用這些類在項目B中完美編碼。

現在我想做JUnit測試

在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
}

這里一切都很好。 所有屬性都正確注入，沒有問題。

現在我需要測試Application Layer {project b}

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

並在applicationContextTest.xml中

<?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>

但是當我運行B測試時，Spring無法找到項目A中定義的屬性。我如何實現這一目標？

更新我將測試xmls移動到Src文件夾，以便maven在項目B中識別並確實識別它。 但是我仍然低於錯誤

Answer 1

如果您正在使用maven，那么src/test中的任何資源和源都是本地的單個模塊，即projectA/src/test任何內容都將從projectB隱藏。 有多種選擇：

• 移動測試資源：我不鼓勵你這樣做，但基本上你可以將applicationContextTest.xml移動到src/main文件夾，但是你的二進制交付項中有測試代碼。

• 復制測試資源：當您將任何bean設置從projectA復制到projectB時，這並不像以前的建議那么projectB 。 這通常意味着您要為單元測試創​​建測試應用程序上下文，並且您的實際應用程序具有不同的應用程序上下文。

• 刪除所有測試應用程序上下文：這將是最干凈的解決方案，如果您沒有任何測試上下文，您將被迫測試真實的東西。 如果需要特定於環境的屬性，可以使用PropertyPlaceHolders，如果需要不同的bean（連接池等），則可以使用“個人檔案”。

您的測試持久性上下文xml名稱在項目A和項目B中是相同的。您是否可以嘗試將項目A中的名稱persistenceContextTest.xml更改為persistenceContextTestA.xml ，以確保問題不是因為文件名重復。
