使用通用绑定服务 class

Question

我有一个通用接口

@FunctionalInterface
public interface GenericInterface<T> {

    Optional<T> doSmth(long Id);
}

我有两个实现 classes，例如 GenericInterfaceImpl 和 GenericInterfaceImplImpl，它们都在一个方法中使用自己的 class 作为泛型

public class GenericInterfaceImpl
    implements GenericInterface<OwnClass> {
}

public class GenericInterfaceImplImpl
    implements GenericInterface<OwnClass2> {
}

我还有另外两个classes，应该使用上述服务的依赖项

public class Class1 {
private final GenericInterface<OwnClass> gen;
@Inject
public Class1(GenericInterface<OwnClass> gen) {
this.gen = gen;
}
}

public class Class2 {
private final GenericInterface<OwnClass2> gen2;
@Inject
public Class2(GenericInterface<OwnClass2> gen2) {
this.gen2 = gen2;
}
}

ServiceBinder class

bind(GenericInterfaceImpl.class).to(GenericInterface.class);
bind(GenericInterfaceImplImpl.class).to(GenericInterface.class);

在运行申请后，假设我已经注册了ServiceBinder，我得到了这个错误

Caused by: org.glassfish.hk2.api.UnsatisfiedDependencyException: There was no object available for injection at SystemInjecteeImpl(requiredType=GenericInterface,parent=Class1 etc.)

如何正确绑定？

Answer 1

经过 8 小时的搜索，我找到了解决方案

   bind(GenericInterfaceImpl.class).to(new TypeLiteral<GenericInterface<OwnClass>>() {});
   bind(GenericInterfaceImplImpl.class).to(new TypeLiteral<GenericInterface<OwnClass2>>(){});
