java.lang.IllegalArgumentException:API接口不得扩展其他接口Retrofit 2 [英] java.lang.IllegalArgumentException: API interfaces must not extend other interfaces Retrofit 2

问题描述

我在使用Retrofit 2 beta 2时遇到下一个问题:

I am having the next problem using Retrofit 2 beta 2:

java.lang.IllegalArgumentException: API interfaces must not extend other interfaces.

这是因为我有一个这样的Retrofit API接口:

This is because I have one interface for the API of Retrofit like this:

public interface RetrofitBaseAPI {

    @POST
    Call<LoginResp> login(@Url String url, @Body LoginReq loginReq);

    @POST
    Call<String> logout(@Url String url, @Header("Cookie") String sid);
}

例如，其中之一就是这个:

For example, one of them is this one:

public interface RetrofitWiserLinkAPI extends RetrofitBaseAPI {

    @GET("/rs/DeviceIdentification")
    Call<DeviceId> getDeviceIdentification(@Header("Cookie") String sid);
}

然后，我还有其他三个接口，其中三个是从RetrofitBaseAPI接口扩展的.

And then, I have three other interfaces, the three of them extends from this RetrofitBaseAPI interface.

当我尝试使用给定的接口调用retrofit.create(Class class)时，我总是会收到此错误.

When I try to call the retrofit.create(Class class) with the given interface, I always receive this error.

据我所读，唯一的解决方案是创建三个独立接口.是真的吗有人知道另一种解决方案吗?

As far as I was reading, the only solution is to create three independents interfaces. Is it true? Anybody knows another solution?

我觉得有点奇怪，我们需要复制代码，但是，也许是有一个我不理解的原因.....

I find a little bit weird that we need to duplicate code, but well, maybe there is a reason I don't understand.....

提前谢谢！

谢谢

使用最终的Retrofit 2发行版时出现相同的问题.我想这是Retrofit的一个局限....

Same problem using the final Retrofit 2 release version. I guess it is a limitation from Retrofit....

推荐答案

不可能有基本的Retrofit接口.

It's not possible to have a base Retrofit interface.

JakeWharton :

改造比继承更偏向于组合.每个服务一个接口.

Retrofit favors composition over inheritance. One interface per service.

因此，正如您已经发现的那样，唯一的解决方案是创建三个独立接口.

So as you already found out, the only solution is to create three independents interfaces.
