java - 替换System.setProperty(....)

我有这个简单的JMX客户端

    public void testTomcatBasicAuthentication() throws Exception
    {
        System.out.println("Test Server Basic Authentication");
        try
        {
            String truststore = "C:\\client.jks";
            String trustStorePassword = "password";

            JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://xxx.xxx.xxx.xxx:9999/jmxrmi");

            HashMap environment = new HashMap();
            String[] credentials = new String[]
            {
                "user", "passwd"
            };
            environment.put(JMXConnector.CREDENTIALS, credentials);
//            environment.put("javax.net.ssl.trustStore", truststore);
//            environment.put("javax.net.ssl.trustStorePassword", trustStorePassword);
//            environment.put("javax.net.ssl.keyStore", truststore);
//            environment.put("javax.net.ssl.keyStorePassword", trustStorePassword);

            KeyManager[] kms = getKeyManagers(truststore, trustStorePassword);
            TrustManager[] tms = getTrustManagers(truststore, trustStorePassword);

            System.setProperty("javax.net.ssl.trustStore", truststore);
            System.setProperty("javax.net.ssl.trustStorePassword", trustStorePassword);
            System.setProperty("javax.net.ssl.keyStore", truststore);
            System.setProperty("javax.net.ssl.keyStorePassword", trustStorePassword);

            JMXConnector jmxc = JMXConnectorFactory.connect(url, environment);
            MBeanServerConnection server = jmxc.getMBeanServerConnection();

            Set<ObjectName> s2 = server.queryNames(new ObjectName("Catalina:type=Server,*"), null);
            for (ObjectName obj : s2)
            {
                ObjectName objname = new ObjectName(obj.getCanonicalName());
                System.out.println("serverInfo " + server.getAttribute(objname, "serverInfo"));
                System.out.println("address " + server.getAttribute(objname, "address"));
                System.out.println("stateName " + server.getAttribute(objname, "stateName"));
            }
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }

如何用Java代码替换System.setProperty(....)？我不想使用System.setProperty。

编辑。我发现了这个example

我们可以使用此代码吗？

KeyManager[] kms = getKeyManagers(truststore, trustStorePassword);
            TrustManager[] tms = getTrustManagers(truststore, trustStorePassword);
            SslContext.setCurrentSslContext(new SslContext(kms, tms, null));

private static TrustManager[] getTrustManagers(String location, String password)
        throws IOException, GeneralSecurityException
    {
        // First, get the default TrustManagerFactory.
        String alg = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmFact = TrustManagerFactory.getInstance(alg);

        FileInputStream fis = new FileInputStream(location);
        KeyStore ks = KeyStore.getInstance("jks");
        ks.load(fis, password.toCharArray());
        fis.close();

        tmFact.init(ks);

        // And now get the TrustManagers
        TrustManager[] tms = tmFact.getTrustManagers();
        return tms;
    }

    private static KeyManager[] getKeyManagers(String location, String password)
        throws IOException, GeneralSecurityException
    {
        // First, get the default KeyManagerFactory.
        String alg = KeyManagerFactory.getDefaultAlgorithm();
        KeyManagerFactory kmFact = KeyManagerFactory.getInstance(alg);

        FileInputStream fis = new FileInputStream(location);
        KeyStore ks = KeyStore.getInstance("jks");
        ks.load(fis, password.toCharArray());
        fis.close();

        // Now we initialise the KeyManagerFactory with this KeyStore
        kmFact.init(ks, password.toCharArray());

        // And now get the KeyManagers
        KeyManager[] kms = kmFact.getKeyManagers();
        return kms;
    }

    private static KeyStore keyStoreFromCertificateString(String alias, String certificateString)
        throws NoSuchAlgorithmException, CertificateException, IOException, KeyStoreException
    {
        KeyStore ks = KeyStore.getInstance("jks");
        ks.load(null); // Create empty key store
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        Certificate cert = cf.generateCertificate(new ByteArrayInputStream(certificateString.getBytes()));
        ks.setEntry(alias, new KeyStore.TrustedCertificateEntry(cert), null);
        return ks;
    }

您能否给出一些想法，我们可以如何集成此代码，或者应该有其他解决方案？

最佳答案

我担心您的问题不是很完善。我写了您想替换System.setProperty，但对我来说，实际上，您想使用自定义信任/ key 存储。

这已经得到回答:Using a custom truststore in java as well as the default one

您找到的示例仅是解决方案的一半。创建连接时，必须使用相应的管理器。像这样的东西:

sslContext.init(null, trustManagers, null);
connection.setSSLSocketFactory(sslContext.getSocketFactory());

资料来源:https://planet.jboss.org/post/creating_https_connection_without_javax_net_ssl_truststore_property

但是，如果您不控制实际的连接创建，则可能必须使用全局属性。 (或者您的应用程序服务器具有的任何配置机制)
