嘗試創建測試時注入自動連接的依賴關係失敗

我正在嘗試爲存儲庫創建junit測試，我收到了這個很好的例外。嘗試創建測試時注入自動連接的依賴關係失敗

完全例外：

我有@Repository到位

@Repository 
public class RepositoryJDBC implements RepositoryInterface {

我有一個ApplicationContext-的test.xml設置：

<context:annotation-config /> 
    <context:component-scan base-package="gov.mt.dphhs.sdnh.core" /> 
    <context:component-scan base-package="gov.mt.dphhs.sdnh.web" /> 
    <context:component-scan base-package="gov.mt.dphhs.sdnh.core.domain.impl" /> 
    <mvc:annotation-driven /> 

    <jee:jndi-lookup id="testDataSource" jndi-name="jdbc/newHireDS" /> 

    <!-- 
     Setup Repositories 
    --> 
    <bean id="repositoryJDBC" 
      class="gov.mt.dphhs.sdnh.core.domain.impl.RepositoryJDBC"/>

，這裏是實際junit測試：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = { "classpath*:/applicationContext-test.xml" }) 
public class RepositoryJDBCTest { 

    @Autowired RepositoryJDBC testRepository; 


    private Employee testEmployee; 
    private Employer testEmployer; 
    private List<Employee> employeeList; 
    private DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd"); 

    @BeforeClass 
    public static void setUpClass() throws Exception { 
     // jndi connection information removed 
    } 

    /** 
    * 
    * @throws Exception 
    */ 
    @Test 
    public void testFindEmployee() throws Exception { 
     System.out.println("Find Employee test: "); 
     /* Start the Test */ 
     /* Get the test employee and check that the Employee object is created */ 
     testEmployee = testRepository.findEmployee(123940); // (Integer) 

     assertNotNull(testEmployee); 

     System.out.println("\t found this employee: " + testEmployee.toString()); 
    }

我相信在這個項目中某處沒有設置正確的東西。這是一個繼承的項目。好極了。 –

有時需要bean定義，答案是關閉Eclipse/STS，刪除〜/ .m2/repository目錄，然後重新啓動Eclipse。

有另一位同事在從svn抓取它之後在他的機器上看了這個。它工作得很好。很奇怪。 –

進樣的接口，而不是具體的類：

@Autowired RepositoryInterface testRepository;

它將工作，因爲一旦你申請@Repository註釋，春包裝你原來RepositoryJDBC類的代理。默認情況下，這個代理實現了具體類已經實現的所有接口 - 但不擴展該類。

我試過這個，我得到了同樣的異常，接受了RepositoryInterface而不是RepositoryJDBC的匹配bean。我在接口上應用了'@ Repository'註釋，並從RepositoryJDBC中移除它。然後我把它換回來，仍然有錯誤。每次運行測試前，我都要確保清理項目。 –

@Kodefoo：你確定'RepositoryJDBC'被創建（在構造函數中放置一個斷點）？它沒有'@ Repository'註釋工作嗎？ –

我在構造函數中添加了一個println，它正在輸出中顯示。我也清理並建造了這個項目。刪除註釋使我獲得相同的結果。 –

我認爲<mvc:annotation-driven />與<context:annotation-config />相沖突，然後Repository bean沒有被創建。

刪除<mvc:annotation-driven />和測試（它的作品我試了一下）

另外，當您遇到奇怪的錯誤，你不應該從配置文件

<bean id="repositoryJDBC" class="gov.mt.dphhs.sdnh.core.domain.impl.RepositoryJDBC"/>

刪除了''並刪除了''相同的結果。非常令人沮喪。 –
