Spring 尝试创建测试时，自动连线依赖项的注入失败

我正在尝试为存储库创建一个

junit

测试，我得到了一个很好的异常

完全例外：

我已经准备好了@Repository

@Repository
public class RepositoryJDBC implements RepositoryInterface {

我有applicationContext-test.xml设置：

<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"/>

下面是实际的junit测试：

@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());
    }

@RunWith（SpringJUnit4ClassRunner.class）
@ContextConfiguration（位置={“classpath*：/applicationContext test.xml”}）
公共类RepositoryJDBCTest{
@自动连线存储jdbc测试存储库；
私人雇员；
私人雇主；
私人名单雇员名单；
private DateFormat DateFormat=新的SimpleDateFormat（“yyyy-MM-dd”）；
@课前
公共静态void setUpClass（）引发异常{
//已删除jndi连接信息
}
/**

@试验
public void testFindEmployee（）引发异常{
System.out.println（“查找员工测试：”）；
/*开始测试*/
/*获取测试employee并检查employee对象是否已创建*/
testEmployee=testRepository.findeEmployee（123940）；/（整数）
assertNotNull（测试员工）；
System.out.println（“\t找到此员工：+testEmployee.toString（））；
}

注入接口而非具体类：

@Autowired RepositoryInterface testRepository;

它将起作用，因为一旦应用

@Repository

注释，Spring就会用代理将原始的

RepositoryJDBC

类包装起来。默认情况下，该代理实现所有已经由具体类实现的接口，但不会扩展该类。

我认为

与

冲突，并且然后，不会创建存储库bean

移除

并测试（我试过了，它能正常工作）

另外，您不需要配置文件中的bean定义

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

有时当您遇到奇怪的错误时，答案是关闭Eclipse/STS，删除~/.m2/repository目录，然后重新启动Eclipse。

我尝试了这一点，我得到了相同的异常，即RepositoryInterface没有匹配的bean，而不是RepositoryJDBC。我在I上应用了

@repository

注释接口，并将其从RepositoryJDBC中删除。然后我将其交换回来，仍然存在错误。我确保每次运行测试之前都清理项目。@Kodefoo:是否确实创建了

RepositoryJDBC

（在构造函数中放置断点）？在没有

@Repository

注释的情况下它能工作吗？我在构造函数中添加了一个println，它将显示在输出中。我还清理并构建了该项目。删除注释会得到相同的结果。我将对此给出答案，因为在查看以前的程序时，我遗漏了这一点mer已经做了。删除了

，删除了

相同的结果。非常令人沮丧。我确信这个项目中的某些地方设置不正确。这是一个继承的项目。耶。在从svn抓取它之后，让另一位同事在他的机器上查看了它。它工作正常。非常奇怪。
