mysql - JDBC 连接 : access denied

Question

我正在尝试通过 SSL 与 mysql 建立 JDBC 连接。 我已经将有效证书导入到 cacertsSSL.jks 文件中。 我仍然无法连接。

有没有办法不扩展或更改驱动程序？

public static void getMysqlConnection() {
    Connection connection = null;
    try {

      Class.forName("com.mysql.jdbc.Driver");
      Driver driver = DriverManager.getDriver(URL);
      DriverPropertyInfo[] info = driver.getPropertyInfo(URL, null);

      String URL = "jdbc:mysql://myHost:3307/myDB?verifyServerCertificate=false&requireSSL=true&useSSL=true";
      String USER = "myUser";
      String PASSWORD = "myPwd";

      System.setProperty("javax.net.ssl.keyStore", "C:\\Development\\cacertsSSL.jks");
      System.setProperty("javax.net.ssl.keyStorePassword", "changeit");
      System.setProperty("javax.net.ssl.trustStore", "C:\\Development\\cacertsSSL.jks");
      System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

      Connection conn = DriverManager.getConnection(URL, USER, PASSWORD);
      System.out.println(conn);
    } catch (Exception e) {
      System.out.println("Connection Failed! Check output console");
      e.printStackTrace();
      return;
    }
  }

下面是连接错误堆栈跟踪

回答: 这是它起作用的原因:

  String URL = "jdbc:mysql://myHost:3307/myDB?useSSL=true";
  String USER = "myUser";
  String PASSWORD = "myPwd";

  System.setProperty("javax.net.ssl.trustStore", "C:\\Development\\cacertsSSL.jks");
  System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

在这种情况下，只有 TrustStore 就足够了，在我的情况下，只有 useSSL 有效。 谢谢。

您输入的用户名或密码有误，或者您无法以该用户身份从该主机进行连接。但这也表明 SSL 部分工作正常。
