Question

我有一个像这样构建的类</ p>

class CryptoManager @Inject()(config: Configuration) {

  Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider())

  //Static values for Public Key Encryption
  private val pubkf = KeyFactory.getInstance("ECDSA", "BC")
  private val cspec = ECNamedCurveTable.getParameterSpec("secp192r1")
  private val privkeyString = config.getString("crypto.ECDSA.privkey").get
  private val r = new BigInteger(privkeyString, 16)
  private val ec = new ECPrivateKeySpec(r, cspec)
  private val privKey = pubkf.generatePrivate(ec)
...
}

当我在测试中明确地构建它时，它可以正常工作：

   val config = Configuration.from(Map(
      "crypto" -> Map(
        "ECDSA" -> Map(
          "privkey" -> "b005ec459ad9482997757093df4c70732452083529617227",
          "pubkey" -> "04a4ec3b4e144434283a28c129ad5f2c13effc8dca6c79987bb8298c9be41e9c2f2176c9cacb2da156a095e68383a9f053",
          "bitlength" -> 192),
        "AES" -> Map(
          "secretkey" -> "ee21affe373c6e0e324fee2c0a6060e"
        ),
        "AESMAC" -> Map(
          "secretkey" -> "b9d1c0381f0ac08b27dcb945ff48c533"
        ))))

    val cryptoManager = new CryptoManager(config)

但是当我尝试使用Guice将此类的实例注入另一个类的构造函数时，我收到以下错误

play.api.UnexpectedException: Unexpected exception[ProvisionException: Unable to provision, see the following errors:

我确认应用程序的application.conf文件中的值与我在测试文件中构建的配置对象中的值相同。我还确认privkeyString中的值在两种情况下都是相同的。

我注意到如果我提供如下配置而不是注入它，一切正常：

val config = ConfigFactory.defaultApplication()
val conf = Configuration(config)

但我明白这是做错的“错误”方式，我更愿意弄清楚为什么Guice无法建立我的课程。
