我想为我的Spring MVC应用程序编写一个单元测试用例。我正在使用纯Java配置，没有XML。春季JUnit - java.lang.IllegalStateException：无法加载ApplicationContext
当我尝试运行我的测试类时，我得到以下堆栈跟踪。 （这是堆栈跟踪的只是一部分，完整的跟踪太大张贴在堆栈溢出。）

这里是我的测试类：
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class)
public class CampusParserTest {
@Autowired
ApplicationContext applicationContext;
@Test
public void testParser() {
CampusParser campusParser = new CampusParser();
campusParser.parse();
}
}
出于某种原因，它似乎并不要实例化我的任何bean或找到任何属性/配置文件。这是我在Tomcat 8上运行的Spring MVC应用程序。数据源也是从JNDI加载的，我猜测这将是一个问题，但一次只能做一件事。
更新：这是我的PersistenceConfig。该应用程序加载和运行正常使用Tomcat 8
@Configuration
@EnableTransactionManagement
@MapperScan("org.app.researchportal.core.persistence")
public class PersistenceConfig {
@Autowired
Environment environment;
/**
* Gets the datasource from the container using JNDI and returns it
*
* @return {@link DataSource}
*/
@Bean(name = "datasource")
public DataSource dataSource() {
JndiDataSourceLookup dsLookup = new JndiDataSourceLookup();
dsLookup.setResourceRef(true);
return dsLookup.getDataSource(environment.getRequiredProperty("jndi.datasource"));
}

return sessionFactory;

你有一个循环依赖地方？它看起来像bean'dataSource'想要注入'sqlSessionFactory'，它想要注入'dataSource'，它想要注入'sqlSessionFactory'，它想要......等等。 – Jesper
我更新了这个问题。它在Tomcat中正常工作。无论出于何种原因，似乎不加载属性文件似乎是根本原因 – greyfox
正在加载的属性文件没有“aysnc.executor.poolSize”，这是导致其他人的主要异常。所以添加@propertySource（“文件名”）来加载属性文件。 – Jango
