Połaczenie z baza danych

0

Koledzy co moge zrobić w przypadku kiedy moje połączenie z baza nie wymaga podania jej nazwy, w moim hostingu wystarczy nazwa hosta. Natomiast przy próbie połączenia przez :

<beans:bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource"

		p:url="jdbc:mysql://mysqNazwahosta"
		p:driverClassName="com.mysql.jdbc.Driver " p:username="user"
		p:password="password">
	</beans:bean>

dostaje exception :

Podobno działa na tej zasadzie że np.
Tworze sobie baze danych i ona ma Zewnętrzna nazwa hosta:mysql415.cp.az.pl. Kiedy tworze kolejna Zewnętrzna nazwa hosta to mysql485.cp.az.pl. Czyli wg histingu zeby polaczyc sie z baza danych nalezy wpisac jedynie adres.
Polaczenie z baza 1 wpisujesz mysql415.cp.az.pl.
Polaczenie z baza 2 wpisujesz mysql485.cp.az.pl.
ok dałoby rade ale jezeli w parametrach nie podam nazw bazy wywala mi błąd.

com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Access denied for user 'xxxxxxx_test'@'%' to database 'xxxxxx_baza'
jak dla mnie problemem jest tutaj użytkownik. Może nie ma uprawnień?

Spróbowałem zalogować sie uzytkownikiem ktory jest domyślnym użytkownikiem do zarządzania bazą danych i jest ta sama sytuacja. Cale polaczenie jest ok kiedy testuje to w ponizszy sposob tutaj nie podaje nazwy bazy:

 
public class Runner {

	public static void main(String[] args) {

                String username = "xxxx";
		String password = "yyyy";
		String url = "jdbc:mysql://mysql415.cp.az.pl";// bez podania nazwy bazy

		
		

		System.out.println("-------- MySQL JDBC Connection Demo ------------");
		try {
			Class.forName("com.mysql.jdbc.Driver");
		} catch (ClassNotFoundException e) {
			System.out.println("MySQL JDBC Driver not found !!");
			e.printStackTrace();
			return;
		}
		System.out.println("MySQL JDBC Driver Registered!");
		Connection connection = null;
		try {
			connection = DriverManager.getConnection(url, username, password);
			System.out.println("SQL Connection to database established!");

		} catch (SQLException e) {
			System.out.println("Connection Failed! Check output console");
			e.printStackTrace();
			return;
		} finally {
			try {
				if (connection != null)
					connection.close();
				System.out.println("Connection closed !!");
			} catch (SQLException e) {
				e.printStackTrace();
			}
		}
