无法加载Spring的ApplicationContext在JUnit测试

Question

我有一个像这样下方的JUnit测试：

@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中运行），当我试图执行测试（右键单击类名和运行Junit测试），引发了一个异常，它引用了weblogic类，我不明白为什么会发生这种情况。

我怀疑可能是由于我的pom.xml中的配置错误而引发异常，但我不太确定。该项目部署到weblogic没有问题。

我已经遍历了我的mock-applicationContext.xml和引用的xml文件（存储在src/main/webapp/WEB-INF中），但没有提及任何特定的weblogic。

有关如何解决此问题或采取更多调试方法的任何想法？

Answer 1

的问题似乎是你在你的classpath指向一个META-INF/services/javax.xml.parsers.DocumentBuilderFactory到WebLogic DocumentBuilderFactory实现。

你可以解决：

• 还原到默认的实现：

  例如启动测试与 -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl或添加META-INF/services/javax.xml.parsers.DocumentBuilderFactory到测试类路径指向com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl

• 添加到classpath weblogic实现所需的jar包。

Answer 2

使用wls-api.jar而不是weblogic.jar。
