使用Guice绑定基于输入参数的类实例

public class MyModule extends AbstractModule {
    @Provides
    @Named("instanceA")
    public MyClass provideInstanceA() {
        return new ClassA();
    }

    @Provides
    @Named("instanceB")
    public MyClass provideInstanceB() {
        return new ClassB();
    }
}

public class MyClassConsumer {
    private final Provider<MyClass> instanceAProvider;
    private final Provider<MyClass> instanceBProvider;

    @Inject
    public MyClassConsumer(@Named("instanceA") Provider<MyClass> instanceAProvider,
                           @Named("instanceB") Provider<MyClass> instanceBProvider) {
        this.instanceAProvider = instanceAProvider;
        this.instanceBProvider = instanceBProvider;
    }

    public void doSomething() {
        MyClass instanceA = instanceAProvider.get();
        MyClass instanceB = instanceBProvider.get();

        // 使用获取到的类实例进行操作
        // ...
    }
}
