Ubuntu下Eclipse部署MySQL JDBC驱动

Ubuntu下Eclipse部署MySQL JDBC驱动

1.MySQL JDBC驱动包下载地址：http://dev.mysql.com/downloads/connector/j/

   版本：mysql-connector-java-5.1.17.zip

2.下载后任意目录解压到/mysql-connector-java-5.1.17/mysql-connector-java-5.1.17-bin.jar；

    /mysql-connector-java-5.1.17/目录下还有docs和src文件夹，src文件夹里有lib目录；

3.前提：mysql和eclipse环境都安装好，参照前面blog关于Ubuntu安装j2ee环境和mysql的文章；

4.打开eclispe，进入菜单windows->prefrences，进入Java->Build Path->user libraries，选择新建，命名为mysql，路径为：/mysql-connector-java-5.1.17/mysql-connector-java-5.1.17-bin.jar；

5.创建java project，命名为mysqlcon，右键其，选择Build Path->Add libraries，从列表中选择user library，在next界面中选择上面部署的mysql安装包即可；

6.开发，mysqlcon工程下新建class，命名为my，包为cn，即cn.my的java文件：

Package cn;

import java.sql.*;

public class my{ public static void main(String args[]) { try { Class.forName("com.mysql.jdbc.Driver"); //加载MYSQL JDBC驱动程序 System.out.println("Success loading Mysql Driver!"); } catch (Exception e) { System.out.print("Error loading Mysql Driver!"); e.printStackTrace(); } try { Connection connect = DriverManager.getConnection( "jdbc:mysql://localhost:3306/dbname","root","password"); System.out.println("Success connect Mysql server!");

 //select code Statement stmt = connect.createStatement(); ResultSet rs = stmt.executeQuery("select * from t_auth");//t_auth为表的名称  while (rs.next()) { System.out.println(rs.getString("auth_path"));//auth_path是表t_auth的一个字段

 }

 //insert into code

 PreparedStatement Statement=connect.prepareStatement("INSERT INTO t_auth VALUES(?,?)"); Statement.setString(1,"2"); Statement.setString(2,"系统管理"); Statement.executeUpdate(); } catch (Exception e) { System.out.print("get data error!"); e.printStackTrace(); } } }

能正确显示和插入即成功！
