annotations

问题 I have an Entity called Station . This entity has a property called attributes which is StationAttributes value object. I try to set the property to be StationAttributes : /** * @var StationAttributes * @ORM\Column(name="attributes", type="station_attributes", nullable=true) */ private $attributes; However, the API Platform generates Station model that looks like this: { ... "attributes": "string" } I want it to be like this: { ... "attributes": { "field": true, "field2": "value2", } } How

问题 I'm trying to build up an object graph in some code where I'm using type hint on class attributes in Python 3.6. Generally this look like: class MyObject: some_variable: float = 1.2 My problem is that I would like to have an attribute that has a type MyObject like this: class MyObject: parent: MyObject = None When I try this I get "NameError: name 'MyObject' is not defined" when I try to do this on the annotation. This seems like an unsupported edge case that cannot currently succeed, since

问题 I really do like function annotations, because they make my code a lot clearer. But I have a question: How do you annotate a function that takes another function as an argument? Or returns one? def x(f: 'function') -> 'function': def wrapper(*args, **kwargs): print("{}({}) has been called".format(f.__name__, ", ".join([repr(i) for i in args] + ["{}={}".format(key, value) for key, value in kwargs]))) return f(*args, **kwargs) return wrapper And I don't want to do Function = type(lambda: None)

问题 I have an interface, for example @NameBinding @Retention(RetentionPolicy.RUNTIME) public @interface AutoLogged { boolean query() default false; } How can I get query parameter in interceptor implementation? @Provider @AutoLogged public class AutoLoggedInterceptor implements WriterInterceptor { @Context private ResourceInfo resourceInfo; @Override public void aroundWriteTo(final WriterInterceptorContext context) throws IOException, WebApplicationException { try { final String methodName = this

问题 I am getting different output for the same code while using java 1.7.0_79 and 1.7.0_80 versions for compilation and running. The test code snippet looks like this : interface Constraint<T> extends Serializable { T getValue(); } @Target({ ElementType.METHOD }) @Retention(RetentionPolicy.RUNTIME) @interface NonZero { } public class ReflectionTest { @SuppressWarnings("serial") public static void main(String[] args) { Constraint<Integer> c = new Constraint<Integer>() { @Override @NonZero public

问题 I just created a bundle (successfully), and when I am about to create an entity via console this happened(also with clear:cache): [LogicException] "enable_annotations" on the validator cannot be set as Annotations support is disabled. mi config.yml looks like framework: validation: { enable_annotations: true } serializer: { enable_annotations: true } when i comment the options for validation throws the same Exception but with the serializer when i comment both then it becomes a

问题 I am working on a project that has a dependency of JUnit 4.11 and a transitive dependency of JMock 2.6.0-RC2 who in turn has a dependency of JUnit-dep 4.4 . This transitive dependency of JUnit-dep is overriding the setting in my local pom for JUnit . By overriding, I mean that when I call a JUnit method, it calls the one from v4.4 as opposed to v4.11. Adding exclusions for JMock and for JUnit-dep had no effect on my resolved dependencies. Note: JUnit and JUnit-dep have separate artifactId s,

问题 In my app I'm rotating the MapView according to the device heading, I have only one annotation and i'm rotating it's pin and it's pinView too. My rotation method is inside the next function - (void)locationManager:(CLLocationManager *)manager didUpdateHeading:(CLHeading *)newHeading { if (newHeading.headingAccuracy < 0) return; CLLocationDirection theHeading = ((newHeading.trueHeading > 0) ? newHeading.trueHeading : newHeading.magneticHeading); lastHeading = theHeading; [self rotateImage:self

问题 I'm trying to customize the appearance of the layers of my annotations in mapbox. I want to rotate every annotation layer. - (RMMapLayer *)mapView:(RMMapView *)mapView layerForAnnotation:(RMAnnotation *)annotation { if (annotation.isUserLocationAnnotation) return nil; RMMarker *marker; CGPoint xy = CGPointFromString(annotation.userInfo); marker = [[RMMarker alloc] initWithUIImage:[UIImage imageNamed:@"arrow.png"]]; marker.transform = CATransform3DMakeRotation(atan2f(xy.x, xy.y) * 180 / M_PI,0

问题 Is it possible to inject ejb's into pojo's using the @EJB annotation? If it is, do I have to set up anything special on a JBoss server to make it work? Please let us not discuss the rationale behind doing this - I am just trying to hack some old code to make it work :-) 回答1: Yes, if you can make JBoss create the Pojo for you. Your problem is that you probably call new to create the Pojo and the framework can't intercept this which is why @EJB is ignored. The solution is to use a factory to
