Spring.NoSuchBeanDefinitionException与<预后注释=“已启用”/>的整数？

Question

注:我修正了这个问题。见自己的答案:)

我有一个单元测试，用于测试spring安全性中的不同角色。

所有的身份验证和授权都是通过用户界面实现的，但我似乎无法让它在单元测试中工作。这是我的单元测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"/test-context.xml"})
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
public class UserServiceTest {

  @Autowired
  UserService userService;

  @Test
  public void UserNameAdminMustBeFound(){
    UserDetails userDetails = userService.loadUserByUsername("admin");
    assertEquals(userDetails.getUsername(), "admin");
  }

  @Test (expected = UsernameNotFoundException.class)
  public void UserNotFoundMustThrowException(){
    userService.loadUserByUsername("NotExistingUser");
  }

  @Test
  public void userWithAdminRoleHasAccessToTheMethod(){
    // admin has ADMIN_ROLE
    UserDetails userDetails = userService.loadUserByUsername ("admin");
    assertEquals("admin", userDetails.getPassword());
    this.dummyMethod();
  }

  @Test(expected = AccessDeniedException.class)
  public void userWithReadRoleHasNOAccessToTheMethod(){
    // viewer has VIEWER_ROLE (and thus no ADMIN_ROLE)
    UserDetails userDetails = userService.loadUserByUsername ("viewer");
    assertEquals("viewer", userDetails.getPassword());
    this.dummyMethod();
  }

  @PreAuthorize("hasRole('ADMIN_ROLE')")
  private void dummyMethod(){
      System.out.println("dummyMethod reached");
  }
}

如果我注释掉最后一个测试'userWithReadRoleHasNOAccessToTheMethod'，一切正常。这是最后一个不抛出异常AccessDeniedException的测试。这是因为我需要测试上下文中的全局方法安全前注释=“已启用”标记。

但是，这里有趣的是，如果我将这个标记添加到我的test-context.xml中，那么在所有单元测试中都会出现一种完全不同的错误：

Caught exception while allowing TestExecutionListener [org.springframework.test.context.support.DependencyInjectionTestExecutionListener@43244fd9] to prepare test instance [com.sysunite.qms.services.UserServiceTest@4f651ff]

它说我还没有用id userService来定义bean，但是它以前是有效的，它显然在我的test-context.xml中：

  <bean id="userService" class="com.sysunite.ccy.pms.qms.security.UserService">
    <property name="store" ref="quadStore"/>
    <property name="instanceService" ref="instanceService"/>
  </bean>

  <security:global-method-security pre-post-annotations="enabled"/>

同样，如果我注释掉了预post注释=enabled标记，那么一切都正常，但是我无法测试@preAuthorize注释。有人知道这怎么可能吗？这让我很困惑。

提前感谢！

Answer 1

好吧，这花了我一段时间，但我终于让它起作用了。

基本上有两个主要的错误，我犯了，其中一个你作为一个问题的读者看不见。

在我的UserService类中，我有以下代码：

  @Override
  @PreAuthorize("hasRole('ADMIN_ROLE')")
  public void deleteUser(String username) {
    // implementation of the method
  }

这导致了某种死锁，导致Spring给了Spring.NoSuchBeanDefinitionExceptionerror。我不知道为什么，但是当Spring实例化这个类时，当标记注释= enabled存在时，Spring实际上不能实例化userService类。

我的第二个错误和新的学习点是:当使用@PreAuthorize注释时，始终确保它所在的类被spring上下文实例化。在我的例子中，我在我自己的测试类中有一个方法，它没有被spring上下文实例化。它确实有@RunWith(SpringJUnit4ClassRunner.class)注释，但这显然不是针对Spring :)

谢谢你的帮助:)
