如何在Guice中绑定接口的各种实现
我有一个接口的多个实现的列表。
public class MyInterfaceImplementation1 extends MyInterface {}
public class MyInterfaceImplementation2 extends MyInterface {}
...
List<MyInterface> myInterfaceImplementationList;
myInterfaceImplementationList.add(new MyInterfaceImplementation1);
myInterfaceImplementationList.add(new MyInterfaceImplementation2);
列表被传递到我的 AbstractModule 实现中，我想根据具体类动态绑定它们。 比如：
for (MyInterface c : myInterfaceImplementationList) {
bind(c.getClass()).toInstance(c); //this is not OK
}
现在，这在 Guice 中可能吗？如何实现？
后来我想访问具体的实现：
injector.getInstance(MyInterfaceImplementation1.class);
injector.getInstance(MyInterfaceImplementation2.class);
...
I have a list of multiple implementations of an interface.
public class MyInterfaceImplementation1 extends MyInterface {}
public class MyInterfaceImplementation2 extends MyInterface {}
...
List<MyInterface> myInterfaceImplementationList;
myInterfaceImplementationList.add(new MyInterfaceImplementation1);
myInterfaceImplementationList.add(new MyInterfaceImplementation2);
List is passed into my implementation of AbstractModule, where I would like to bind them dynamically based on concrete Class.
Something like:
for (MyInterface c : myInterfaceImplementationList) {
bind(c.getClass()).toInstance(c); //this is not OK
}
Now, is this possible in Guice and how?
Later I would like to access concrete implementation:
injector.getInstance(MyInterfaceImplementation1.class);
injector.getInstance(MyInterfaceImplementation2.class);
...

但这有点令人费解。还有更好的建议吗？
What I could do is:
and then:
But this is a bit convoluted. Any better suggestion?
