禁用JDBC连接上的keystore

Question

我有一个使用ConnectorJ连接到MySQL DB的应用程序，没有问题。但是，我现在需要扩展应用程序，以便对另一个端点执行相互身份验证的HTTP请求。

我的问题是，为HTTP请求定义客户机密钥存储库似乎会导致在JDBC连接中也使用该密钥存储库。MySQL数据库不期望提供证书，握手失败，如下所示:

源(简化)

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class DbTester {
    private static final String JDBC_DRIVER = "com.mysql.jdbc.Driver";
    private static final String JDBC_URL = "jdbc:mysql://XXX.XXX.XXX.XXX/mysql?useSSL=true";
    private static final String JDBC_USERNAME = "xxxxxxxxxx";
    private static final String JDBC_PASSWORD = "xxxxxxxxxx";
    public static void main(final String[] args) throws Exception {
        Class.forName(JDBC_DRIVER);
        Connection connection = DriverManager.getConnection(JDBC_URL, JDBC_USERNAME, JDBC_PASSWORD);
        try (PreparedStatement statement = connection.prepareStatement("select 1 from user")){
            try (ResultSet results = statement.executeQuery()) {
                if (results.next()) {
                    System.out.println("Query Result: " + results.getString(1));
                }
            }
        }
    }
}

完整性测试运行(成功输出):

> java -cp .:mysql-connector-java-5.1.24-bin.jar DbTester
Query Result: 1

生成任意密钥:

keytool -genkey -keyalg RSA -keystore myKeystore。JKS -storepass password

使用指定的密钥重新运行(失败!!):

java -cp .:mysql-connector-java-5.1.24-bin.jar -Djavax.net.ssl.keyStore=myKeystore.jks -Djavax.net.ssl.keyStorePassword=password DbTester

EDIT/SOLVED

我通过显式地为HTTP连接加载证书(并删除jvm级环境参数)来实现此工作:

        String certPath = System.getProperty("my.cert.path");
        String certPassword = System.getProperty("my.cert.password");
        in = new FileInputStream(new File(certPath));
        KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
        ks.load(in, certPassword.toCharArray());
        in.close();
        KeyManagerFactory kmf = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
        kmf.init(ks, certPassword.toCharArray());
        KeyManager[] keymanagers = kmf.getKeyManagers();
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(keymanagers, null, null);
        SSLSocketFactory sslSocketFactory = context.getSocketFactory();
        HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
        connection.setSSLSocketFactory(sslSocketFactory);
        // do HTTP connection OPS :)

MySQL数据库不期望提供证书

但是它要求一个!如果服务器没有发送CertificateRequest消息，客户机就不会提供证书。要么你的客户端不被MySQL接受，这可以通过MySQL端配置来修复，要么MySQL不应该要求客户端证书，这也可以在MySQL端修复。
