Calling init() inside the constructor is not an option since init() could be overriden by a subclass. 回答1: You can use `@PostConstruct' in guice when you use the mycila/jsr250 extension . This will cause your init() method to be called right after instantiation. @PostConstruct void init() { //

This explains "Annotation with Attributes". But, I'm not sure of the explanation. Binding Annotations with Attributes Guice supports binding annotations that have attribute values. In the rare case that you need such an annotation: Create the annotation @interface. Create a class that implements the annotation interface. Follow the guidelines for equals() and hashCode() specified in the Annotation Javadoc. Pass an instance of

My question is how to inject members of all the setter-based injection classes using injector.injectMembers() method? //I am calling this method in init method of my application private static final Injector injector = Guice.createInjector(new A(), new B()); //Injecting dependencies using setters of all classes bound in modules A and B injector.injectAllMembers()?? 回答1: Why do you need to inject

How exactly does this proxying work? If I just throw enough classes behind interfaces, will everything be fine? (I know that circular dependencies are usually a code smell, but I think in this case it's ok.) 回答1: While the "inject an interface" approach is totally valid, and might even be the better solution in some occasions, in general, you can use a simpler solution: Providers. For every class "A"

A question about Guice. I'm still learning it, but I can understand the fundamentals. This question was already asked a couple of times on the net, but never with a concrete answer(none that I could find). Say I have a situation like on the picture(a similar example was somewere on the net). public class Dog {} public class Walk implements Walkable { private final Dog dog; private final boolean leash; @Inject public Walk(Dog dog, @Assisted boolean leash) { this.dog = dog; this.leash = leash; } public void go() { } } public interface Walkable { void go(); } public interface WalkFactory { Walk

What I would like to do is find all bindings for some type that is parameterised by a wildcard type but I can't figure out how to do it. A look at the guice src suggests I might be barking up the wrong tree but I figured I'd ask around anyway... so for example given a type Foo < E extends Bar > BarImplOne implements Bar BarImplTwo implements
