引发okhttp异常的RoboSpice

Question

我使用调用我的服务器REST，直到几天前，每个调用都抛出一个异常，直到几天前，该api才开始正常工作：

D/Retrofit: java.lang.NoSuchMethodError: No direct method <init>(Lcom/squareup/okhttp/OkHttpClient;Lcom/squareup/okhttp/Request;ZZZLcom/squareup/okhttp/Connection;Lcom/squareup/okhttp/internal/http/RouteSelector;Lcom/squareup/okhttp/internal/http/RetryableSink;Lcom/squareup/okhttp/Response;)V in class Lcom/squareup/okhttp/internal/http/HttpEngine; or its super classes (declaration of 'com.squareup.okhttp.internal.http.HttpEngine' appears in /data/app/com.company.app.customerapp-1/base.apk)

D/Retrofit: ---- END ERROR

依赖关系：

compile 'com.octo.android.robospice:robospice:1.4.14'
compile 'com.octo.android.robospice:robospice-cache:1.4.14'
compile 'com.octo.android.robospice:robospice-retrofit:1.4.14'

我怀疑在例外情况下编译器有问题，但我刚刚在另一台计算机上测试了Java和Android在同一项目上的新安装，但问题仍然相同……

这个错误快把我逼疯了。

有人知道什么能帮上忙吗？任何帮助都是非常感谢的。

编辑

MainActivity.java：

SpiceManager spiceManager = new SpiceManager(TestAPIService.class);

protected void onStart() {
    super.onStart();

    spiceManager.start(this);

    spiceManager.execute(new TestRequest(), new RequestListener<ResponseData>() {
        ...
    });
}

TestAPIService.java：

public class TestAPIService extends RetrofitGsonSpiceService {

    @Override
    public void onCreate() {
        super.onCreate();
        addRetrofitInterface(TestAPI.class);
    }

    @Override
    protected String getServerUrl() {
        return "http://192.168.0.2";
    }
}

TestAPI.java：

public interface TestAPI {
    @GET("/test")
    ResponseData getTest();
}

TestRequest.java：

public class TestRequest extends RetrofitSpiceRequest<ResponseData, TestAPI> {

    public TestRequest() {
        super(ResponseData.class, TestAPI.class);
    }


    @Override
    public ResponseData loadDataFromNetwork() throws Exception {
        ResponseData response;

        try {
            response = getService().getTest();
        }
        catch (Exception e) {
            e.printStackTrace();
            throw e;
        }

        return response;
    }
}

Answer 1

之所以发生NoSuchMethodError，是因为HttpURLConnectionImpl试图在未定义的HttpEngine上调用构造函数。现在，您的项目依赖于：

com.octo.android.robospice:robospice-retrofit:1.4.14

哪个取决于

com.squareup.retrofit:retrofit:1.6.1

哪个取决于都是：

com.squareup.okhttp:okhttp:2.0.0

和

com.squareup.okhttp:okhttp-urlconnection:2.0.0

在版本2.0.0中，HttpURLConnectionImpl在okhttp-urlconnection模块中，HttpEngine在okhttp模块中。堆栈跟踪的retrofit.client.UrlConnectionClient部分与retrofit:1.6.1正确匹配，但com.squareup.okhttp.internal.huc.HttpURLConnectionImpl部分与okhttp-urlconnection:2.0.0不匹配；它与okhttp-urlconnection:2.4.0匹配。NoSuchMethodError正在抱怨的构造函数确实是在okhttp:2.4.0中定义的，因此这意味着您的类路径上有一个不同的HttpEngine，这很可能来自于由传递依赖项引入的不同版本的okhttp。您应该能够通过指定以下依赖项来解决这个问题：

compile('com.squareup.okhttp:okhttp:2.0.0') {
    force = true
}
compile('com.squareup.okhttp:okhttp-urlconnection:2.0.0') {
    force = true
}

如果这样做不起作用，那么您的问题的解决方案仍然是让您的okhttp和okhttp-urlconnection版本同步起来，并且与您的retrofit版本兼容。声明类似于上面的依赖项，找到包含HttpURLConnectionImpl和HttpEngine、弄清楚他们是怎么被拉到你的建筑里的的jars，并使用排除消除问题的传递依赖关系。
