Spring JUnit-java.lang.IllegalStateException：无法加载ApplicationContext

Question

我试图为我的Spring MVC应用程序编写一个单元测试用例。 我使用的是纯Java Config，没有XML。

当我尝试运行测试类时，得到以下堆栈跟踪。 （这只是堆栈跟踪的一部分。完整的跟踪太大，无法在堆栈溢出时发布。）

这是我的测试课：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class)
public class CampusParserTest {

    @Autowired
    ApplicationContext applicationContext;

    @Test
    public void testParser() {

        CampusParser campusParser = new CampusParser();
        campusParser.parse();
    }
}

由于某种原因，它似乎没有实例化我的任何bean或查找任何属性/配置文件。 这是我在Tomcat 8上运行的Spring MVC应用程序。数据源也从JNDI加载，我猜这将是一个问题，但一次只能做一件事。

更新：这是我的PersistenceConfig。 该应用程序可以在Tomcat 8中加载并正常运行。

@Configuration
@EnableTransactionManagement
@MapperScan("org.app.researchportal.core.persistence")
public class PersistenceConfig {

    @Autowired
    Environment environment;

    /**

     *
     * @return {@link DataSource}

    @Bean(name = "datasource")
    public DataSource dataSource() {
        JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
        dsLookup.setResourceRef(true);
        return dsLookup.getDataSource(environment.getRequiredProperty("jndi.datasource"));
    }

        UserTransactionManager userTransactionManager = new UserTransactionManager();
        userTransactionManager.setForceShutdown(false);
        return userTransactionManager;

我认为您必须忘记配置“数据源”，例如：

 <property name="driverClassName" value=
 <property name="url" value=
