相关疑难解决方法(0)

所以我将MySQL Connector/J 5.1.16添加到我的项目的Build Path中.我正在使用默认的OSX Java包和MAMP Pro 1.9.4与MySQL 5.1.44和Eclipse.

我已经使用以下函数设置了一个简单的Java应用程序:

private static String dbUrl = "jdbc:mysql://127.0.0.1:3306/mpp";
private static String dbUsername = "root";
private static String dbPassword = "root";

private Statement statement = null;

private void dbConnect() {


try {
    Class.forName("com.mysql.jdbc.Driver");
    Connection connection = DriverManager.getConnection(dbUrl, dbUsername, dbPassword);
    statement = connection.createStatement();

} catch(SQLException e) {
    System.err.print(e.getMessage() + " ARGH!");
} catch(Exception e) {
    System.err.print(e.getMessage() + " FUUUUUUUUUU!");
}
}

当我运行它时,我收到以下错误:

Communications link failure

The last packet sent successfully to the server was 0 …
