Spring 3 单元测试

Question

我正在尝试为我的 DAO 类编写一个单元测试，但问题是我收到此错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name  'com.yeah.server.dao.UserDAOTest': Injection of autowired dependencies failed; nested   exception is org.springframework.beans.factory.BeanCreationException: Could not autowire   field: private com.yeah.server.dao.UserDAO com.yeah.server.dao.UserDAOTest.userDAO; nested   exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.yeah.server.dao.UserDAO] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}

这是我的 applicationContext 文件

这是我的测试文件

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath:**/applicationContext.xml"})
@TransactionConfiguration(transactionManager = "transactionManager", defaultRollback =     false)
@Transactional
public class UserDAOTest {

private static Logger log = Logger.getLogger(UserDAOTest.class);
@Autowired
private UserDAO userDAO;

@Test
public void getItemById() {

    User user = null;
    long id = 1;
    user = userDAO.getItemById(id);
    assertNotNull(user); 

}
}

Answer 1

找不到依赖项的 [com.yeah.server.dao.UserDAO] 类型的匹配 bean

您的组件扫描看起来很奇怪：

它应该是一个包而不是一个模式。
尝试：

Answer 2

这是一个猜测，但是：

<context:component-scan base-package="com.yeah.server.*" />

应该是

<context:component-scan base-package="com.yeah.server" />

没有 .* 它不是路径，只是包名称
