1 下载安装Connector/J，下载地址：mysql/products/connector/。Connector/J是专门针对MySQL而开发的JDBC驱动程序包。
2 将安装目录下的mysql-connector-java-5.1.36-bin.jar添加到环境变量的classpath，或者添加到项目的Java Build Path。
3 JDBC基本编程的步骤：

加载驱动
其使用的方法有Class.forName()或者
Class.forName().newInstance()或者
new DriverName() 连接数据库
DriverManager.getConnection() 执行SQL语句
Connection.CreateStatement()
Statement.executeQuery()
Statement.executeUpdate() 取得结果集
while(rs.next()) 显示数据
将数据库中的各种类型转化为java中的类型（getXXX）方法 关闭
close the resultset
close the statement
close the connection

实例：

package ms;import java.sql.Connection;import java.sql.DriverManager;import java.sql.SQLException;import java.sql.Statement;import java.sql.ResultSet;public class TestMySQL {    public static void main(String[] args){        ResultSet rs = null;        Statement stmt = null;        Connection conn = null;        try{            Class.forName("com.mysql.jdbc.Driver"); //创建该字符串标识的类的实例            String url = "jdbc:mysql://localhost:3306/test"; //标识一个被注册的驱动程序            String user = "root";            String pwd = "";            conn = DriverManager.getConnection(url, user, pwd);            stmt = conn.createStatement();            String query = "select * from person where age > 18";            rs = stmt.executeQuery(query);            while (rs.next()){                String id = rs.getString("id");                String name = rs.getString(2);                int age = rs.getInt("age");                System.out.println(id + "\t" + name + "\t" + age);            }        }        catch (ClassNotFoundException e){            e.printStackTrace();        }        catch (SQLException e){            e.printStackTrace();        }        finally {            try{                if (rs != null){                    rs.close();                }                if (stmt != null){                    stmt.close();                }                if (conn != null){                    conn.close();                }            }            catch (SQLException e){                e.printStackTrace();            }        }    }}

PreparedStatement的预处理语句：

String sql = "insert into person values(?,?,?)";PreparedStatement pstmt = conn.prepareStatement(sql);pstmt.setString(1, "005");pstmt.setString(2, "Zhao");pstmt.setInt(3, 18);pstmt.executeUpdate();

statement语句的批处理：

Statement stmt = conn.createStatement();stmt.addBatch("insert into person values('006', 'Zeng', 26)");stmt.addBatch("insert into person values('007', 'Liu', 24)");stmt.addBatch("insert into person values('008', 'Zeng', 17)");stmt.executeBatch();

PreparedStatement语句的批处理

String sql = "insert into person values(?,?,?)";PreparedStatement pstmt = conn.prepareStatement(sql);pstmt.setString(1, "006");pstmt.setString(2, "Zeng");pstmt.setInt(3, 26);pstmt.setString(1, "007");pstmt.setString(2, "Liu");pstmt.setInt(3, 24);pstmt.setString(1, "008");pstmt.setString(2, "Zeng");pstmt.setInt(3, 17);pstmt.executeUpdate();
