annotations

问题 I have what seems to be a simple problem, as stated in the title. Here is the kind of class I have : public class Foo { @Autowired public Foo(@Qualifier("bar") Set<String> bar) { // ... } } Which I try to run with the following spring context : <context:annotation-config /> <util:set id="bar"> <value>tata</value> <value>titi</value> <value>toto</value> </util:set> <bean id="foo" class="Foo" /> This fails to run with : No matching bean of type [java.lang.String] found for dependency

问题 I’m writing from Argentina, forgive my English little. I’m having some problems with modules ZfcUser and zfcuserDoctrineORM . I need to integrate them into my project. I’m working with Zend framework 2 , doctrine 2.3 and postgreSQL and this is the first time I work with these tools. For that reason, there are many things that I don’t dominate well, I have all the modules included in my /config/application.config.php and my connection is configured in my database in /config/autoload/local.php

问题 In my project there's a common base class that all client classes extend. This has an @Autowired field that needs to be injected by Hibernate. These are all grouped together in another class that has an @Autowired collection of the base class. In order to reduce boilerplate for client code I'm trying to get @Component inherited. With @Component not doing this by default (apparently it used to though), I created this workaround annotation @Target(ElementType.TYPE) @Retention(RetentionPolicy

问题 I'm trying to create a new annotation with which I'll do some runtime wiring, but, for a number of reasons, I'd like to verify at compile time that my wiring will be successful with some rudimentary checks. Suppose I create a new annotation: @Target(ElementType.FIELD) @Retention(RetentionPolicy.RUNTIME) public @interface CustomAnnotation{ } Now I want to do some kind of validation at compile time, like check the field that CustomAnnotation annotates is of a particular type: ParticularType . I

问题 I'm trying to make an iPhone app which requires users to be able to long press on a place on a map view to drop a pin there. Does anybody know how this is done? The behaviour is observable in apple maps when you long press on the screen. It will drop a pin and present an annotation saying "dropped pin" 回答1: 1) Instantiate a UILongPressGestureRecognizer and add it to the MKMapView . 2) When the selector gets called after the user has a long press, call the addAnnotation method in MKMapView

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . I've observed the strange fact (based on the questions in the hibernate tag) that people are still actively using xml files instead of annotations to specify their ORM (Hibernate/JPA) mappings. There are a few cases, where this is necessary: you are using classes that are

问题 I have a Java class with a property like this private Object myObj; When I try to save the class using Hibernate annotations, I get the rather confusing error message "property mapping has wrong number of columns". What is the correct approach to persisting a class containing a generic property such as this? 回答1: As you said, the object can be image, video, and more. If it is supposed to have only binary data, you can create another class, and transfer the data from this one. In the process

问题 I am using Google Chart's column graph chart. The chart is a stacked column chart with annotations for every data point of the stacked column. The annotation are at the top of the inside of the bar but I would like them to be centred inside of the bar. The closest solution I found was moving the annotation of a non stacked column google chart to the bottom here. The problem with this solution is that the code looks for annotation that are white and moves them to the bottom. The graph I am

问题 I am not being able to make @Autowire annotation work with a @Repository annotated class. I have an interface: public interface AccountRepository { public Account findByUsername(String username); public Account findById(long id); public Account save(Account account); } And the class implementing the interface annotated with @Repository : @Repository public class AccountRepositoryImpl implements AccountRepository { public Account findByUsername(String username){ //Implementing code } public
