Class.forName("org.gjt.mm.mysql.Driver").newInstance();

String url ="jdbc:mysql://localhost/softforum?user=soft&password=soft1234&useUnicode=true&characterEncoding=8859_1"

前提是你有JDBC驱动....

//function:query data from databse coffeebreak,TABLE COFFEES
import java.sql.*;
public class Query
{
public static void main(String [] args)
{
String url = "jdbc:mysql://localhost/coffeebreak";
Connection con;
Statement stmt;
String qu = "select COF_NAME, PRICE from coffees where PRICE<9.0";
try
{
Class.forName("com.mysql.jdbc.Driver");//看起来虽然不顺眼，但是可以支持中文
}
catch(ClassNotFoundException e)
{
System.err.println("Class Not Found!");
System.err.println("e.getMessage()");

}
try
{
con = DriverManager.getConnection(url,"root","");
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(qu);
System.out.println("Coffee Break Coffees and Prices:");
while(rs.next())
{
String name = rs.getString("COF_NAME");
float price = rs.getFloat("PRICE");
System.out.println("Coffee Name: "+name+" Price: "+price);
}

}
catch(SQLException e)
{
System.err.println("SQLException:"+e.getMessage());
}
}
}
