ApplicationContext始终为空

我正在处理Spring 3 Web服务应用程序，并且正在尝试从我的servlett.xml文件加载ApplicationContext以用于简单的测试用例，但它不起作用。ApplicationContext始终为空

ApplicationContext始终为空。

这是我的测试代码：

@RunWith(SpringJUnit4ClassRunner.class) 
    @ContextConfiguration(locations = { "file:war/WEB-INF/FreedomSpring-servlett.xml" }) 
    public class UserControllerTest { 

     private UserController controller; 

     @Inject 
     private ApplicationContext applicationContext; 

     private String jsonUser = "{ \"username\":\"jonneymendoza\",\"emailAddress\":\"[email protected]\", \"password\":\"12345678\",\"firstName\":\"jono\", \"surname\":\"richy\", \"country\":\"united kingdom\",\"bio\":\"Bio stuff goes here about the user. where he comes from etc etc. all is well. lets go go go\" }"; 

     @Before 
     public void setup() { 
      controller = new UserController(); 

      assertNotNull(applicationContext); 

     } 

     @Test 
     public void testLogin() { 
      fail("Not yet implemented"); 
     } 

     @Test 
     public void testCreateNewAccount() { 

      ResponseEntity<String> response = controller 
        .createNewAccount(new HttpEntity<String>(jsonUser)); 
      assertEquals(HttpStatus.CREATED, response.getStatusCode()); 

     } 

     @Test 
     public void testGetUserProfile() { 
      fail("Not yet implemented"); 
     } 

    }

它设置未按ApplicationContext已空。我想basicaly加载我的bean在这个测试用例上，并在这里使用它们，但自动装配UserService类对象，如下面在我的控制器类中所示。

@Controller 
public class UserController { 
    @Autowired 
    private UserService userService;

xml文件定义我的服务豆：我失去了

servett下面？

编辑：我NPW得到在控制台输出

另一个编辑此错误：通过使用JUnit 4.4代替固定上述的junit错误。现在我们回到关于ApplicatyionContext的原始问题。

这是错误的堆栈跟踪每当我跑我的测试：

如果您使用的是文件，您可能需要确保（a）您已明确设置测试执行目录，或（b）指定完整的路径名。 IMO使用类路径资源要容易得多。 –

当你的应用程序试图构建'ApplicationContext'时，你能看到日志吗？必须有一些错误，并且您可以从该日志中获得帮助。 –

我已经在“file：war/WEB-INF/FreedomSpring-servlett.xml”下指定了完整的路径名，但它似乎不起作用？ – jonney

看来，@RunWith(SpringJUnit4ClassRunner.class)注释丢失，或只是一个错误，当复制并粘贴？

不是一个真正的答案，但希望它会帮助你排除故障（它为我做的）。添加@RunWith(SpringJUnit4ClassRunner.class)到类像这样：

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = {"file:///c:/project/target/META-INF/spring/applicationContext.xml"}) 
public class SpringContextTest { 
    ... 
}

这将至少给你的日志，因此它会更容易，看看发生了什么事情。要么是不正确的文件路径，要么是上下文定义中的问题，例如一个无效的bean定义。

注：在我的例子中，绝对路径绝对没有，这是实验的一部分 - 它应该真的依赖于classpath:位置。

更新：更新的堆栈跟踪表明在运行测试时（java.lang.NoClassDefFoundError：javax/servlet/ServletException），您在类路径中没有Java Servlets API。确保在类路径中包含罐子servlet-api-2.5.jar（或类似的）。

谢谢我添加@Runwith并在日志中得到这个错误： – jonney

编辑检查编辑问题的日志 – jonney

更新了答案 – maksimov

我也竭尽全力来应付这一问题3-4 hours..but最后当我加入了下面的代码，以我的测试类....

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(locations = { "file:///D:/PRMS_Workspace/PRMS/WebContent/WEB-INF/dispatcher-servlet.xml" })

它的工作了。
