Ubuntu下eclipse部署mysql jdbc驱动

配置JDBC用到的

原文地址：/article/8660449.html

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！
