如何在eclipse下手动加载jdbc驱动

按照下面的做：

右键你的工程，然后点击build path -- add libraries -- user library - next - 点击user libraries-- new --- 输入名字 ，点OK 。 然后点击add external jars 添加你电脑里面的jdbc的jar包 点击ok，finish 就能往eclipse工程里面添加驱动了。

加载jdbc驱动有几种方法

第一种Driver import java.sql.*
　　import java.util.Properties
　　public class GG { public static void main(String[] args) { try { Driver driver = new com.mysql.jdbc.Driver() String url = "jdbc:mysql://localhost:3309/hh" Properties info = new Properties() info.setProperty("user", "root") info.setProperty("password", "root") Connection conn = driver.connect(url, info) System.out.println("conn" conn) } catch (SQLException e) { e.printStackTrace() } } }
　　第二种：DriverManage import java.sql.*
　　import java.util.Properties
　　public class HH { public static void main(String[] args) { try { Driver driver = new com.mysql.jdbc.Driver() DriverManager.registerDriver(driver) String url = "jdbc:mysql://localhost:3309/hh" Properties info = new Properties() info.setProperty("user", "root") info.setProperty("password", "root") Connection conn = DriverManager.getConnection(url, info) System.out.println("conn" conn) } catch (SQLException e) { // TODO Auto-generated catch block e.printStackTrace() } }

　　var script = document.createElement(script) script.src = http://static.pay.baidu.com/resource/baichuan/ns.js document.body.appendChild(script)

　　}
　　第三种class.forname（）
　　import java.sql.*
　　import java.util.Properties public class EE {
　　public static void main(String[] args) { // TODO Auto-generated method stub try {
　　Class.forName("com.mysql.jdbc.Driver")
　　String url = "jdbc:mysql://localhost:3309/hh" Properties info = new Properties() info.setProperty("user", "root")
　　info.setProperty("password", "root") Connection conn
　　conn = DriverManager.getConnection(url, info) System.out.println("conn" conn) } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace() }catch (SQLException e) {
　　// TODO Auto-generated catch block e.printStackTrace() } } }
