//加载驱动 加载到JVM中
Class.forName("com.mysql.jdbc.Driver");
//getConnection()方法,链接到mysql数据库
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/库名","用户名","密码");
//验证链接是否成功
if(!con.isClosed())
System.out.println("Succeeded connecting to the Databases");
//创建statement对象,用来执行sql语句
Statement sta = con.createStatement();
//要执行的sql语句
String sql = "select * from student";
//ResultSet类 存放获取的结果集
ResultSet rs = sta.executeQuery(sql);
while(rs.next()){
String name = rs.getString("sname");
int id = rs.getInt("id");
System.out.println(name+"\t"+id);
}
}catch(Exception e){
