Question

我创建了一个密钥库（.jks），我使用以下代码在IDE中访问它

KeyStore ks = KeyStore.getInstance("JKS");
FileInputStream ksfis = new FileInputStream(keyStorePath);
BufferedInputStream ksbufin = new BufferedInputStream(ksfis);
ks.load(ksbufin, spass.toCharArray());

但是当我制作JAR文件时它出错了。在搜索问题之后，我开始知道我必须使用

InputStream is = this.getClass().getClassLoader().getResourceAsStream(FilePath);

但是此代码为我提供了InputStream，我的代码希望ksfis为FileInputStream。有人可以建议我替代期望FileInputStream的代码。

更新 - MCVE

package com.token;

import java.io.BufferedInputStream;
import java.io.InputStream;
import java.security.KeyPair;
import java.security.KeyStore;
import java.security.PrivateKey;
import java.security.PublicKey;

public class test {

   static final String keyStorePath = "Keys/keystore_pkcs8.jks";
   static final String alias = "mykey";
   static final String spass = "passwordhere";
   static final String kpass = "passwordhere";

   private static KeyPair getKeyPairFromKeyStore() throws Exception {

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

    //problem with this part of code
    Config conf = new Config();
    InputStream ksfis = conf.getFileInputStream(keyStorePath);
    BufferedInputStream ksbufin = new BufferedInputStream(ksfis);
    ks.load(ksbufin, spass.toCharArray());

    PrivateKey privateKey = (PrivateKey) ks.getKey(alias, kpass.toCharArray());
    java.security.cert.Certificate cert = ks.getCertificate(alias);
    PublicKey publicKey = cert.getPublicKey();

    return new KeyPair(publicKey, privateKey);
}

public static void main(String[] args) {
    try {
        KeyPair ks = getKeyPairFromKeyStore();
    }
    catch(Exception e) {
        System.out.println(e.toString());
    }
  } 
}

配置类 -

package com.token;

import java.io.InputStream;

class Config {
    public InputStream getFileInputStream(String FilePath) throws Exception{
        InputStream is = this.getClass().getClassLoader().getResourceAsStream(FilePath);
        return is;
    }
}
