Zip4J -> java.security.ProviderException: 无法构建 MacSpi 实例

Question

我正在尝试使用 lingala zip4j 来归档 X509Certificate 个文件。

但是，只有在使用 Junit 进行单元测试时，我才会遇到这个奇怪的异常。

如果我运行我的应用程序作为产品（这是一个 spring 网络应用程序）- 它工作正常，没有例外，我能够正确地归档和取消归档文件，没有问题。

这是我的 Utils 代码，它存档了我使用过的证书：

        bytes = outputStream.toByteArray();


        return bytes;

        // Set key strength
        zipParameters.setAesKeyStrength(Zip4jConstants.AES_STRENGTH_256);

        // Set password
        zipParameters.setPassword(password);
        return zipParameters;
    }
}

我正在使用 Java 1.6

我也试过使用 1.8，但我遇到了同样的错误。

注意：这仅在我运行使用 Junit 时发生...

Answer 1

我发现运行 PowerMockRunner.class 的测试导致了这个问题的发生。

我不确定为什么会这样。我能够通过反射创建我的模拟来克服这个问题，而不必使用 PowerMock.

我已经解决了眼前的问题，但这是一个非常奇怪的问题，如果有人知道为什么会这样，我仍然想知道。

添加这个会有所帮助 - @PowerMockIgnore({"javax.crypto.*" })
