没有类型的限定bean ...期望至少1个bean有资格作为此依赖关系的autowire候选者

标签： spring hibernate spring-data autowired inject

我正在尝试在此项目中注入Repository bean，但不断获取：

引起：org.springframework.beans.factory.BeanCreationException：无法自动装配字段：private org.todo.services.TaskReader org.todo.services.AbstractTest.taskReader;嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：没有为依赖项找到类型为[org.todo.services.TaskReader]的限定bean：期望至少有一个bean可以作为此依赖项的autowire候选者。依赖注释：{@ javax.inject.Inject（）}

引起：org.springframework.beans.factory.NoSuchBeanDefinitionException：找不到类型为[org.todo.services.TaskReader]的限定bean用于依赖：预期至少有1个bean符合此依赖关系的autowire候选者。依赖注释：{@ javax.inject.Inject（）}

项目结构：

java
  org.todo
   model
     repository 
       TaskRepository
   services
     TaskReader
       impl
         TaskReaderImpl
resources
  config
    applicationContext.cfg.xml
    persistence.cfg.xml
  META-INF 
    persistence.xml
test
 org.todo.services
  AbstractTest

任务阅读器：

    public interface TaskReader {
    TaskItem findOne(long id);

    List<TaskItem> findByOwner(ToDoUser toDoUser);

    List<TaskItem> findAll();
}

任务阅读器实施：

@Service

@Transactional(readOnly = true)

public class TaskReaderImpl implements TaskReader {

    @Resource
    private TaskRepository taskRepository;
    @Inject
    private UserReader userReader;
...

TaskRepository：

    @Repository
public interface TaskRepository extends CrudRepository<Task, Long> {

    @Query("select t from tasks t where t.owner = :user order by t.done, t.startedDate")
    List<Task> findAllByOwner(@Param("user") User user);

    @Query("select t from tasks t order by t.done, t.startedDate")
    List<Task> findAll();

    @Query("delete from tasks t where t.owner= :user")
    void deleteAllByOwner(@Param("user") User user);
}

我在某些测试中使用TaskReader：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath*:config/applicationContext.cfg.xml")
public class AbstractTest {
    @Inject
    private TaskReader taskReader;
    @Inject
    private TaskWriter taskWriter;
    @Inject
    private UserWriter userWriter;
    @Inject
    private UserReader userReader;

现在我被赋予了autowired bean的错误，但我找不到这个错误！
