控制器測試 - CacheManager已關閉。它不能再使用

Question

我正在嘗試使用Guice嘗試使用Play framework 2.4.6進行控制器測試時遇到錯誤。它發生在Controller中的任何view.render代碼中。 redirect不會產生此問題。

堆棧：

1) Error in custom provider, java.lang.IllegalStateException: The CacheManager has been shut down. It can no longer be used.

下面是我的設置：

控制器：

@Singleton 
public class AccountController extends Controller { 
    private AccountService accountService; 

    @Inject 
    public Controller(AccountService a) { 
     accountService = a; 
    } 

    public Result addAccount() { 
    boolean success = accountService.addAccount(); 
    if (success) 
     return ok(CreateAccount.render());//<--THIS TRIGGERS THE ERROR WHEN RUNNING THE TEST 
    } 
} 

接口：

@ImplementedBy(AccountServiceImpl.class) 
public interface AccountService { 
    boolean addAccount(); 
} 

實現：

public class AccountServiceImpl implements AccountService { 
    @Override 
    public boolean addAccount() { 
    } 
} 

測試：

public class TestClass { 
@Inject 
Application application; 

final AccountService accountServiceMock = mock(AccountService.class); 

@Before 
public void setup() { 
    Module testModule = new AbstractModule() { 
     @Override 
     public void configure() { 
      bind(AccountService.class).toInstance(accountServiceMock); 
     } 
    }; 

    GuiceApplicationBuilder builder = new GuiceApplicationLoader() 
      .builder(new ApplicationLoader.Context(Environment.simple())) 
      .overrides(testModule); 
    Guice.createInjector(builder.applicationModule()).injectMembers(this); 

    Helpers.start(application); 
} 

@Test 
public void testMethod() throws Exception { 
    RequestBuilder request = new RequestBuilder() 
      .session("userId", "1") 
      .uri(controllers.routes.AccountController.addAccount().url()); 

    running(application,() -> { 
     when(accountServiceMock.addAccount().thenReturn(true); 
     assertEquals(OK, route(request).status()); 
    }); 

} 

任何他LP讚賞！

編輯：我確定了導致問​​題的確切的東西，但我仍然不知道爲什麼。

RequestBuilder request = new RequestBuilder() 
      .session("userId", "1") // <--- THIS IS CAUSING THE PROBLEM 
      .uri(controllers.routes.AccountController.addAccount().url()); 

爲了更加準確：

"userId" // <--- THIS. userIds, or any other I've tried, solved the issue. 

爲了能夠長時間再次恢復，因爲userId會話時，測試方法與控制器view.render沿設置RequestBuilder，這個錯誤發生。

這是不管我是否在我的html或甚至在控制器中使用這樣的會話。任何人都知道這裏發生了什麼？

移動測試方法裏面一切的running調用內部：

running(application,() -> { 
    RequestBuilder request = new RequestBuilder() 
     .session("userId", "1") 
     .uri(controllers.routes.AccountController.addAccount().url()); 

    when(accountServiceMock.addAccount().thenReturn(true); 
    assertEquals(OK, route(request).status()); 
}); 

的running method停止應用程序，然後你在你的assert路由的請求時，得到一個錯誤。
