AKKA remote (使用SSL)无法在类路径上找到密钥存储/信任存储文件

Question

我正在尝试配置AKKA连接以使用我的keystore和trustore文件，我希望它能够在类路径上找到它们。

我试图将application.conf设置为：

...
remote.netty.ssl = {
        enable = on
        key-store = "keystore"
        key-store-password = "passwd"
        trust-store = "truststore"
        trust-store-password = "passwd"
        protocol = "TLSv1"
        random-number-generator = "AES128CounterSecureRNG"
        enabled-algorithms = ["TLS_RSA_WITH_AES_128_CBC_SHA"]
    }
...

如果keystore和trustore文件位于当前目录中，则工作正常。在我的应用程序中，这些文件被打包到WAR和JAR档案中，因此我想从类路径中读取它们。

我试图在application.conf中使用application.conf中的这里，但没有任何结果。Config将其逐字读取为字符串。

我还试图解析字符串conf并强制它读取值：

val conf: Config = ConfigFactory parseString (s"""
...
"${getClass.getClassLoader.getResource("keystore").getPath}" 
...""")

在本例中，它以file://some_dir/target/scala-2.10/server_2.10-1.1-one-jar.jar!/main/server_2.10-1.1.jar!/keystore的形式在类路径上找到正确的路径，这正是它所在的位置(在jar中)。但是，基础Netty传输在此路径下找不到文件，我得到：

我想知道在AKKA中是否有任何方法可以在不实现自定义SSL传输的情况下配置它。也许我应该在代码中配置Netty？

显然，我可以对路径进行硬编码，或者从环境变量中读取路径，但我更喜欢更灵活的类路径解决方案。

我决定查看抛出异常的代码的akka.remote.netty.NettySSLSupport，下面是代码：

  def initializeServerSSL(settings: NettySettings, log: LoggingAdapter): SslHandler = {
log.debug("Server SSL is enabled, initialising ...")

def constructServerContext(settings: NettySettings, log: LoggingAdapter, keyStorePath: String, keyStorePassword: String, protocol: String): Option[SSLContext] =
  try {
    val rng = initializeCustomSecureRandom(settings.SSLRandomNumberGenerator, settings.SSLRandomSource, log)
    val factory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm)
    factory.init({
      val keyStore = KeyStore.getInstance(KeyStore.getDefaultType)
      val fin = new FileInputStream(keyStorePath)
      try keyStore.load(fin, keyStorePassword.toCharArray) finally fin.close()
      keyStore
    }, keyStorePassword.toCharArray)
    Option(SSLContext.getInstance(protocol)) map { ctx ⇒ ctx.init(factory.getKeyManagers, null, rng); ctx }
  } catch {
    case e: FileNotFoundException    ⇒ throw new RemoteTransportException("Server SSL connection could not be established because key store could not be loaded", e)
    case e: IOException              ⇒ throw new RemoteTransportException("Server SSL connection could not be established because: " + e.getMessage, e)
    case e: GeneralSecurityException ⇒ throw new RemoteTransportException("Server SSL connection could not be established because SSL context could not be constructed", e)
  }

看起来它必须是一个普通的文件名(字符串)，因为这是FileInputStream需要的。

欢迎任何建议！

在撰写本问题时，AFAIK没有办法做到这一点。我在结束这个问题，但我欢迎更新，如果新的版本提供这样的功能，或如果有其他方式这样做。

Answer 2

我也被困在了类似的问题中，并且得到了类似的错误。在我的例子中，我试图使用akka-http访问具有自签名证书的https服务器，并使用我能够通过的以下代码：

val trustStoreConfig = TrustStoreConfig(None, Some("/etc/Project/keystore/my.cer")).withStoreType("PEM")
val trustManagerConfig = TrustManagerConfig().withTrustStoreConfigs(List(trustStoreConfig))

val badSslConfig = AkkaSSLConfig().mapSettings(s => s.withLoose(s.loose
  .withAcceptAnyCertificate(true)
  .withDisableHostnameVerification(true)
).withTrustManagerConfig(trustManagerConfig))

val badCtx = Http().createClientHttpsContext(badSslConfig)

Http().superPool[RequestTracker](badCtx)(httpMat)
