真的需要帮助。我使用JUnit（4.6）和Spring（3.0.5）进行单元测试。当我尝试在我的测试类中自动装入服务对象时，出现NoSuchBeanDefinitionException异常。@ JUnit＆Spring的自动失败
JUnit的代码：
package com.aaa.service.impl;
@ContextConfiguration(locations = { "classpath:/spring/applicationContext.xml",
"classpath:/spring/applicationContext-aop.xml",
"classpath:/spring/applicationContext-dao.xml",
"classpath:/spring/applicationContext-service.xml" })
@RunWith(SpringJUnit4ClassRunner.class)
public class TestManageTargetServiceImpl {
@Autowired
ManageTargetServiceImpl manageTargetServiceImpl;
@Test
public void testQueryFinancialMonthList() {
List<Map<String, Object>> value = new ArrayList<Map<String, Object>>();
ManageTargetDao manageTargetDao = mock(ManageTargetDao.class);
when(manageTargetDao.queryFinancialMonthList()).thenReturn(value);
manageTargetServiceImpl.setManageTargetDao(manageTargetDao);
// I hope it return null
assertNull(manageTargetServiceImpl.queryFinancialMonthList());
}
}
ApplicationContext的-service.xml的代码：
<context:annotation-config />
<bean id="manageTargetService" class="com.aaa.service.impl.ManageTargetServiceImpl">
<property name="manageTargetDao" ref="manageTargetDao"></property>
</bean>
错误的轨道：

您确定stacktrace中没有其他错误吗？也许manageTargetService不能在容器中因为一些错误等而创建（或者因为没有找到manageTargetDao - 它必须是可用的，因为它在xml中被指定为属性） –
在这里猜测 - 但是如果注入一个类类型' ManageTargetServiceImpl'失败，我认为原因是为'ManageTargetServiceImpl'创建了一个代理，所以bean的类型不再是'ManageTargetServiceImpl'，而是该类的接口。 –
嗨，Biju，你是对的，谢谢。我添加了aop方法并在'ManageTargetServiceImpl'上声明了事务。而我只是试图去除aops，@Autowired的作品。谢谢！ @Biju Kunjummen – Albert
