这是源码
import java.sql.*;
public class sqltest {
public static void main(String args[]) {
try {
Class.forName("com.mysql.jdbc.Driver"); //加载MYSQL JDBC驱动程序
//Class.forName("org.gjt.mm.mysql.Driver");
System.out.println("Success loading Mysql Driver!");
}
catch (Exception e) {
System.out.print("Error loading Mysql Driver!");
e.printStackTrace();
}
try {
Connection connect = DriverManager.getConnection(
"jdbc:mysql://localhost:3306/shopping","root","123456");
//连接URL为 jdbc:mysql//服务器地址/数据库名，后面的2个参数分别是登陆用户名和密码
System.out.println("Success connect Mysql server!");
Statement stmt = connect.createStatement();
ResultSet rs = stmt.executeQuery("select * from login");
//user 为你表的名称
while (rs.next()) {
System.out.println(rs.getString("name"));
}
}
catch (Exception e) {
System.out.print("get data error!");
e.printStackTrace();
}
}
}
