java - @Autowired BeanCreationException 与 JUnit

转载作者：行者123 更新时间：2023-12-02 03:36:23

我知道这个问题已经被问过很多次了，但我已经被这个问题困扰了几天，无法弄清楚为什么会发生这种情况。

这是我的 JUnit 测试套件，当我尝试 @Autowire RequestService 时出现问题:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:**/*.xml"})
public class RequestServiceTest {
    @Autowired
    private RequestService requestService;

    @Test
    public void add() throws Exception {
        requestService.add(new Request(1, "hello"));
        requestService.add(new Request(2, "hi"));
        Request requestResponseFromDatabase = (Request) requestService.findById(1);
        assertEquals("hello", requestResponseFromDatabase.getRestRequestParameters());
    }
}

下面是我的模型、DAO 和服务类的代码。

模型(为简洁起见，省略了构造函数和其他字段)

@Entity
public class Request implements Serializable {

    @Id
    private Integer restRequestId;

    private Timestamp restRequestTimestamp;

    private String restRequestParameters;
}

<小时/>

DAO

@Component
public class RequestDAO {

    @Autowired
    private RequestService requestService;

    @PersistenceContext
    private EntityManager entityManager;

    public void persist(Request request) {
        entityManager.persist(request);
    }

    public void update(Request request) {
        entityManager.getTransaction().begin();
        entityManager.merge(request);
        entityManager.getTransaction().commit();
    }

    public Object findById(Serializable id) {
        Request request = entityManager.find(Request.class, id);
        if (request == null) {
            throw new EntityNotFoundException("Cannot find Request for ID " + id);
        }
        return request;
    }

    public void delete(Request request) {
        entityManager.getTransaction().begin();
        entityManager.remove(request);
        entityManager.getTransaction().commit();
    }

    public void deleteById(Serializable id) {
        Request request = entityManager.find(Request.class, id);
        if (request == null) {
            throw new EntityNotFoundException("Cannot find Request for ID " + id);
        } else if (request != null) {
            entityManager.getTransaction().begin();
            entityManager.remove(request);
            entityManager.getTransaction().commit();
        }
    }

    public List<Request> findAll() {
        Query query = entityManager.createQuery("SELECT e from Request e");
        List<Request> requests = query.getResultList();
        return requests;
    }

    public void deleteAll() {
        List<Request> requests = findAll();
        for (Request request : requests) {
            delete(request);
        }
    }

}

<小时/>

服务

@Component
public class RequestService {

    @Autowired
    private RequestDAO requestDAO;

    @Transactional
    public void add(Request request) {
        requestDAO.persist(request);
    }

    @Transactional
    public void update(Request request) {
        requestDAO.update(request);
    }

    @Transactional
    public Object findById(Serializable id) {
        return requestDAO.findById(id);
    }

    @Transactional
    public void delete(Request request) {
        requestDAO.delete(request);
    }

    @Transactional
    public void deleteById(Request request) {
        requestDAO.delete(request);
    }

    @Transactional
    public void deleteAll() {
        requestDAO.deleteAll();
    }

    @Transactional
    public void addAll(Collection<Request> requestCollection) {
        for (Request request : requestCollection) {
            requestDAO.persist(request);
        }
    }

    @Transactional(readOnly = true)
    public List<Request> findAll() {
        return requestDAO.findAll();
    }
}

其他详细信息

Spring 版本:4.2.5.RELEASE
hibernate 版本:5.1.0.Final
我的 spring.xml 位于 src/main/resources 中(是的，我知道这不是最佳实践，但想确保我的测试首先工作。我确实尝试将其保留在我的 src/test/resources 中文件夹，但一直遇到无法加载 ApplicationContext 的问题)

关注的资源:

关于如何解决这个问题有什么想法吗？我过去曾问过类似的问题，并深表歉意——很难理解 Spring 及其所有文档。我想确保我完全理解这一点，以避免将来犯同样的错误。
