Question

我正在尝试做类似

的事情

URL clientks = com.messaging.SubscriptionManager.class.getResource( "client.ks" );
String path = clientks.toURI().getPath();
System.setProperty( "javax.net.ssl.keyStore", path);

其中client.ks是存储在我正在运行的jar文件中的com / messaging中的文件。

读取javax.net.ssl.keyStore的东西需要一个到jar中的client.ks文件的路径。如果可能的话，我宁愿不提取文件并放入客户端的机器上。那么可以在jar中引用文件吗？

这不起作用，因为getPath（）返回null。还有另一种方法吗？

仍然致力于实现，但我相信可以通过InputStream从jar加载密钥库，并以编程方式显式设置TrustStore（vs设置系统属性）。请参阅文章：Setting multiple truststore on the same JVM

搞定了！

InputStream keystoreInput = Thread.currentThread().getContextClassLoader()
    .getResourceAsStream(<path in jar>/client.ks");
InputStream truststoreInput = Thread.currentThread().getContextClassLoader()
    .getResourceAsStream(<path in jar>/client.ts");
setSSLFactories(keystoreInput, "password", truststoreInput);
keystoreInput.close();
truststoreInput.close();

private static void setSSLFactories(InputStream keyStream, String keyStorePassword, 
    InputStream trustStream) throws Exception
{    
  // Get keyStore
  KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());    

  // if your store is password protected then declare it (it can be null however)
  char[] keyPassword = keyStorePassword.toCharArray();

  // load the stream to your store
  keyStore.load(keyStream, keyPassword);

  // initialize a key manager factory with the key store
  KeyManagerFactory keyFactory = 
  KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());    
  keyFactory.init(keyStore, keyPassword);

  // get the key managers from the factory
  KeyManager[] keyManagers = keyFactory.getKeyManagers();

  // Now get trustStore
  KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());    

  // if your store is password protected then declare it (it can be null however)
  //char[] trustPassword = password.toCharArray();

  // load the stream to your store
  trustStore.load(trustStream, null);

  // initialize a trust manager factory with the trusted store
  TrustManagerFactory trustFactory = 
  TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());    
  trustFactory.init(trustStore);

  // get the trust managers from the factory
  TrustManager[] trustManagers = trustFactory.getTrustManagers();

  // initialize an ssl context to use these managers and set as default
  SSLContext sslContext = SSLContext.getInstance("SSL");
  sslContext.init(keyManagers, trustManagers, null);
  SSLContext.setDefault(sslContext);    
}

您可以在jar文件中获取InputStream资源，但不能获得File。如果最终读取密钥库的“事物”需要File或文件路径，那么您唯一的选择就是将其提取到文件系统。

这是user2529737's answer的清理版本，如果有帮助的话。它删除了不需要的信任存储设置，并添加了所需的导入，密钥库类型和密钥密码的参数。

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.KeyManager;
import javax.net.ssl.KeyManagerFactory;
import javax.net.ssl.SSLContext;
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import java.security.KeyStore;

public class PlainJavaHTTPS2Test {

    public void setUp() throws Exception {
        final String KEYSTOREPATH = "clientkeystore.p12"; // or .jks

        // store password can be null if there is no password
        final char[] KEYSTOREPASS = "keystorepass".toCharArray();

        // key password can be null if there is no password
        final char[] KEYPASS = "keypass".toCharArray();

        try (InputStream storeStream = this.getClass().getResourceAsStream(KEYSTOREPATH)) {
            setSSLFactories(storeStream, "PKCS12", KEYSTOREPASS, KEYPASS);
        }
    }
    private static void setSSLFactories(InputStream keyStream, String keystoreType, char[] keyStorePassword, char[] keyPassword) throws Exception
    {
        KeyStore keyStore = KeyStore.getInstance(keystoreType);

        keyStore.load(keyStream, keyStorePassword);

        KeyManagerFactory keyFactory =
                KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());

        keyFactory.init(keyStore, keyPassword);

        KeyManager[] keyManagers = keyFactory.getKeyManagers();

        SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(keyManagers, null, null);
        SSLContext.setDefault(sslContext);
    }
}

如何在jar中使用javax.net.ssl.keystore中的文件？
