JDBC：連接到遠程mySQL數據庫？

Question

    public void readDataBase() throws Exception {
    try {
        // This will load the MySQL driver, each DB has its own driver
        Class.forName("com.mysql.jdbc.Driver");
        // Setup the connection with the DB
        connect = DriverManager
                .getConnection("jdbc:mysql://185.28.21.11/u505743489_db?"+ "user=u505743489_db&password=password");

        // Statements allow to issue SQL queries to the database
        statement = connect.createStatement();
        // Result set get the result of the SQL query
        resultSet = statement
                .executeQuery("select * from FEEDBACK.COMMENTS");
        writeResultSet(resultSet);

        // PreparedStatements can use variables and are more efficient
        preparedStatement = connect
                .prepareStatement("insert into  FEEDBACK.COMMENTS values (default, ?, ?, ?, ? , ?, ?)");
        // "myuser, webpage, datum, summary, COMMENTS from FEEDBACK.COMMENTS");
        // Parameters start with 1
        preparedStatement.setString(1, "Test");
        preparedStatement.setString(2, "TestEmail");
        preparedStatement.setString(3, "TestWebpage");
        preparedStatement.setDate(4, new java.sql.Date(2009, 12, 11));
        preparedStatement.setString(5, "TestSummary");
        preparedStatement.setString(6, "TestComment");
        preparedStatement.executeUpdate();

        preparedStatement = connect
                .prepareStatement("SELECT myuser, webpage, datum, summary, COMMENTS from FEEDBACK.COMMENTS");
        resultSet = preparedStatement.executeQuery();
        writeResultSet(resultSet);

        // Remove again the insert comment
        preparedStatement = connect
                .prepareStatement("delete from FEEDBACK.COMMENTS where myuser= ? ; ");
        preparedStatement.setString(1, "Test");
        preparedStatement.executeUpdate();

        resultSet = statement
                .executeQuery("select * from FEEDBACK.COMMENTS");
        writeMetaData(resultSet);

    } catch (Exception e) {
        throw e;
    } finally {
        close();
    }

}

我嘗試了這段代碼，但是它給出了：
線程“主”中的異常java.sql.SQLException：null，來自服務器的消息：“主機'mobile-130-126-255-40.near.illinois.edu'不允許連接到此MySQL服務器”

我用谷歌搜索，似乎必須授予數據庫特權，但是我不知道我的MySQL命令提示符在哪里。 有什么辦法可以在phpMyAdmin中授予特權？
任何幫助，將不勝感激！

Answer 1

點擊Windows + r，然后在其中鍵入“ cmd”，然后按Enter。這將打開Windows的命令提示符。

然后去.. mysql -u用戶名-p press_enter_key

然后輸入密碼

即

第1行：mysql -u root -h localhost -p

第2行：管理員

其中“ admin”是您的密碼。

然后..

mysql>將所有在databasename。*上的權限授予“ password”標識的cmsuser @ localhost；
