Question

我面临一个非常奇怪的错误。这个错误今天开始发生，它在星期五工作，没有任何改变，至少我不知道。

我有一个简单的KeyStore，我存储一个密钥来加密一些数据。仅用于测试创建的单独应用程序来处理此问题。这是代码：

public static void main(String[] args) {

    Properties prop = new Properties();
    try {

       prop.load(new FileInputStream("./security/security.properties"));

       String ksFile = prop.getProperty("KSFile");
       String ksPassword = prop.getProperty("KSPassword");
       String keyAlias = prop.getProperty("KeyAlias");
       String keyPassword = prop.getProperty("KeyPassword");
       prop.getProperty("CardDataEncryptionKey");

       KeyStore ks;
       ks = KeyStore.getInstance("JCEKS");

       FileInputStream fis = null;
       fis = new FileInputStream(ksFile);

       ks.load(fis, ksPassword.toCharArray());


       // For symmetric
       char[] keycharArray = keyPassword.toCharArray();
       ProtectionParameter proParam = new KeyStore.PasswordProtection( keycharArray );

       KeyStore.Entry entry = ks.getEntry( keyAlias, proParam );
       SecretKeyEntry aeskey = (KeyStore.SecretKeyEntry) entry;         

       aeskey.getSecretKey();


       fis.close();

    } catch (Exception e) {
        e.printStackTrace();
    }
}

代码非常基础，只需打开security.properties中配置的密钥库即可。问题是现在我在以下行中收到错误：

       KeyStore.Entry entry = ks.getEntry( keyAlias, proParam );

我重复这一点并没有发生，只是突然开始。文件没问题，路径没问题，文件打开了，但是当我尝试获取KeyEntry时，我得到一个NumberFormatException，真的没有线索是否发生了什么。这是错误堆栈跟踪：

请大家，给我一点希望！谢谢！

最后这是一个Eclipse问题，也不知道它为什么会发生。在我更改域密码后，即使我重新启动Windows两次，我也开始收到此错误。

谁知道！感谢。
