PS：在之前的博客中详细的介绍了JAVA怎么用JDBC连接数据库，包括SQL Server和Oracle，用JDBC连接MySQL除了加载驱动和获得连接不同，其他都是一样的操作。

附上以前的博客：Java操作Oracle、Java操作数据库

加载驱动

Class.forName("com.mysql.jdbc.Driver");

获取连接

ct = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/mydb1?useUnicode=true&characterEncoding=UTF-8","root", "密码");

案例：

package com.jdbc;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.PreparedStatement;
import java.sql.SQLException;
/*** * @author Switch* @function Java通过JDBC操作MySQL数据库* */
public class JDBC3 {public static void main(String[] args) {Connection ct = null;PreparedStatement ps = null;ResultSet rs = null;try {// 1、加载驱动Class.forName("com.mysql.jdbc.Driver");// 2、获得连接// 连接带上参数保证不会出现中文乱码ct = DriverManager.getConnection("jdbc:mysql://127.0.0.1:3306/mydb1?useUnicode=true&characterEncoding=UTF-8","root", "密码");// 3、创建PreparedStatementps = ct.prepareStatement("select * from t3");// 4、执行操作rs = ps.executeQuery();// 5、操作结果while (rs.next()) {System.out.println(rs.getInt(1) + " " + rs.getString(2) + " "+ rs.getString(3));}} catch (Exception e) {// TODO: handle exceptione.printStackTrace();} finally {try {rs.close();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}rs = null;try {ps.close();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}ps = null;try {ct.close();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}ct = null;}}
}
