Getting multiple guice singletons of the same type

阅读更多关于 Getting multiple guice singletons of the same type

问题 can you get 2 singleton instances of the same underlying type? this is obviously trivial in spring as it is based on named instances to which you attach a scope but I can't see the equivalent in guice which is about binding types to implementation classes. Note that I don't want to have to bind to the instance as the instances in question are injected with other dependencies by guice. 回答1: It's easy in Guice too! Create two biding annotations, say @One and @Two and then bind(MySingleton.class

Guice puzzler: Batch scoped Encapsulated Context

阅读更多关于 Guice puzzler: Batch scoped Encapsulated Context

问题 We are preparing to begin using Guice in our insurance data conversion platform and I have encountered an interesting scenario that does not seem to be directly addressed in the Guice docs or any postings I have found. Our platform uses the Encapsulated Context (EC) pattern in several important areas. For example, imagine we are processing a set of 10 policies. Whenever we begin processing a new policy, we wish to construct a PolicyContext object and initialize properties such as policy

Why use/develop Guice, when You have Spring and Dagger? [closed]

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 3 years ago . To my knowledge, Dagger does generate code, while Guice and Spring rely on runtime processing, thus Dagger works faster, but requires more work on programmer side. Because of performance edge it's good for mobile (Android) development. However, when we are left with Guice and

阅读更多关于 Guice: Using parameter in Module (JndiIntegration)

问题 I've a module like this public class JNDITransactionModule implements Module{ @Override public void configure(Binder binder) { binder.bind(TransactionManager.class) .toProvider( JndiIntegration.fromJndi( TransactionManager.class, "URI TO TRANSACTION MANAGER")) .in(Scopes.SINGLETON); } } Well, I think my question is easy, but... how can I parametrize the "URI TO TRANSACTION MANAGER" value?? I mean, something like this public class JNDITransactionModule implements Module{ @Override public void

Guice: How to change injection on runtime based on a (dynamic web property)

阅读更多关于 Guice: How to change injection on runtime based on a (dynamic web property)

问题 The following is an approximation of the problem I'm facing. Think we have a password validator with some rules. public interface RuleChecker{ //Checks for a password strenght, returns 10 //for strong or 0 for soft password. int check(String pass); } And then we have several implementations, our service will only accept the password if it is over 8 score. public class NoCheck implements RuleChecker { public int check(String pass){return 10;} } public class LengthCheck implements RuleChecker{

How to prevent reuse of EntityManager with guice-persist and @Transactional?

阅读更多关于 How to prevent reuse of EntityManager with guice-persist and @Transactional?

问题 According to this question, when using guice-persist , EntityManager is transaction-scoped. If I understand correctly, this means that a new EntityManager will be created for every transaction. When using guice-persist , it is suggested to use JpaPersistModule , which provides all the bindings, and simply inject Provider<EntityManager> into some class, like this: public class ProjectDAO { private final Provider<EntityManager> entityManagerProvider; @Inject public ProjectDAO(Provider

How can I mix Guice and Jersey injection?

阅读更多关于 How can I mix Guice and Jersey injection?

问题 I've already seen the following question on how to inject @Context dependencies into Jersey resource constructors. But my question is slightly different -- I'd like to inject a @PathParam String. I have a class resembling the following: @Path("foo/{fooId}/bar") public class BarResource { @Inject public BarResource(@PathParam("fooId") String foo, Service service) { ... } ... } The Service is injected fine by Guice, but the path segment is always null. This actually surprises me; if anything I
