1、配置好環境,主要是安裝mysql和下載串連需要的包(我用的是mysql-connector-java-5.1.3-rc-bin.jar)

2、註冊驅動  Class.forName("com.jdbc.mysql.Driver");

3、建立串連  Connection con = DriverManager.getConnection("jdbc:mysql://127.0.0.1/test",user,password);

4、建立運算式 Statement stmt = con.createStatement();

5、執行sql語句並獲得相應的結果集 ResultSet rs = stmt.executeQuery("select * from tables");

6、擷取結果while(rs.next()){System.out.println(rs.getString(1));}

7、關閉串連rs.close();stmt.close();con.close();

public class Jdbc01 {public static void main(String[] args) throws Exception {  Driver  d = new Driver();  DriverManager.registerDriver(d);//Class.forName("com.mysql.jdbc.Driver");Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb","root","123456");//本機  ,連接埠是預設的,資料庫。使用者名稱,密碼。Statement stmt = conn.createStatement();ResultSet rs = stmt.executeQuery("select *from student");//執行查詢語句while(rs.next()){int id = rs.getInt("id");String name = rs.getString("name");int age = rs.getInt("age");String sex = rs.getString("sex");String address = rs.getString("address");System.out.println(id+"  "+name+"   "+age +"   "+ sex+"   " + address);}rs.close();stmt.close();conn.close();}}
