無法加載Spring的ApplicationContext在JUnit測試

Question

我有一個像這樣下方的JUnit測試：

@Configurable(autowire = Autowire.BY_NAME) 
@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = {"file:C:/ProgramData/Eclipse/Projects_3.7.1/project/src/main/webapp/WEB-INF/mock-applicationContext.xml"}) 
public class DaoTest { 
    @Autowired 
    Dao dao; 

    @Test 
    public void simpleTest() { 
     org.junit.Assert.assertNotNull(dao); 
    } 
} 

（使用maven在Eclipse 3.7中運行），當我試圖執行測試（右鍵單擊類名和運行Junit測試），引發了一個異常，它引用了weblogic類，我不明白爲什麼會發生這種情況。

我懷疑可能是由於我的pom.xml中的配置錯誤而引發異常，但我不太確定。該項目部署到weblogic沒有問題。

我已經遍歷了我的mock-applicationContext.xml和引用的xml文件（存儲在src/main/webapp/WEB-INF中），但沒有提及任何特定的weblogic。

有關如何解決此問題或採取更多調試方法的任何想法？

Answer 1

的問題似乎是你在你的classpath指向一個META-INF/services/javax.xml.parsers.DocumentBuilderFactory到WebLogic DocumentBuilderFactory實現。

你可以解決：

• 還原到默認的實現：

  例如啓動測試與 -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl或添加META-INF/services/javax.xml.parsers.DocumentBuilderFactory到測試類路徑指向com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl

• 添加到classpath weblogic實現所需的jar包。

Answer 2

使用wls-api.jar而不是weblogic.jar。
