Ubuntu下eclipse部署mysql jdbc驱动

时间:2016-05-04 22:57来源:linux.it.net.cn 作者:IT

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!
