本地GAE截止日期超过了经常保存的时间

Question

我正在尝试使用Objectify建立本地GAE数据存储区，并希望使用包含车辆颜色的vehicleummary类来保存并加载它：

private Closeable closeable;
private final LocalServiceTestHelper helper = new LocalServiceTestHelper(
        new LocalDatastoreServiceTestConfig(),
        new LocalMemcacheServiceTestConfig());

@Before
public void setUp() {
    helper.setUp();
    ObjectifyService.init(new ObjectifyFactory(DatastoreOptions
            .newBuilder().setHost("http://localhost:8080")
            .setProjectId("my-project").build().getService(),
            new AppEngineMemcacheClientService()));
    ObjectifyService.register(VehicleSummary.class);
    closeable = ObjectifyService.begin();
}

@After
public void tearDown() {
    closeable.close();
    helper.tearDown();
}


@Test
public void test() {
    VehicleSummary veh_summary = new VehicleSummary ("red");

    ObjectifyService.ofy().save().entity(veh_summary).now();
}

运行此命令，数据存储区将在返回时进行初始化

AM com.google.appengine.api.datastore.dev.LocalDatastoreService init
INFORMATION: Local Datastore initialized: 
Type: High Replication
Storage: In-memory

但行

ObjectifyService.ofy().save().entity(veh_summary).now();

未被覆盖，并且最终中止：

com.google.cloud.datastore.DatastoreException: Deadline exceeded
