我有2个应用程序上下文，其中一个导入另一个（appContext-middleware - ＆gt; 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);
}
}
并且没有导入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启动会失败，如下所示

我认为它因为内核中的propertyConfigurer而失败，不知怎么它在中间件导入时无法使用，但我不明白为什么，
答案 0 :(得分：1)
问题应该是SLF4J API jar。确保类路径中没有重复的jar。如果存在将它们排除并将这些依赖项添加到类路径中，则这应该适合您使用的hibernate版本。
