我有两个导入另一个的应用程序上下文（appContext-middleware-> appContext-core）
当我用下面的测试用例测试appContext-core时，它工作正常，
@Transactional
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("/applicationContext-core.xml")
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback = true)
public class DaoTest {
@Autowired
UsersDao usersDao;
@Test
public void testUsers() throws Exception {
Assert.assertNotNull(usersDao);
}
}
而且也无需导入appContext-core appContext-middleware也可以正常工作
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:applicationContext-middleware.xml")
public class TestSomeService {
@Autowired
SomeService someService;
@Test
public void getBeans() {
Assert.assertNotNull(someService);
}
}
但是当我在appContext-middleware中导入appContext-core时，bean初始化失败，如下所示

我认为它失败是因为core中的propertyConfigurer，以某种方式无法在中间件导入时使用它，但是我不明白为什么，
最佳答案
问题应该出在SLF4J API罐子上。确保您的类路径中没有重复的jar。如果存在，请排除它们并将这些依赖项添加到您的类路径中，这应该适合您使用的休眠版本。
