如何用Java连接Aurora MySQL

本篇文章给大家分享的是有关如何用Java连接Aurora MySQL，小编觉得挺实用的，因此分享给大家学习，希望大家阅读完这篇文章后可以有所收获，话不多说，跟着小编一起来看看吧。

以下是使用Mysql-connector 连接Aurora for mysql：

Workbench 访问Aurora，跟mysql方式一致，如： Aurora.example.rds.cn-northwest-1.amazonaws.com.cn

用户名：root

密码：root

Eclipse 开发首先在Maven添加依赖，如下：  

<dependency>    <groupId>mysql</groupId>    <artifactId>mysql-connector-java</artifactId>    <version>8.0.15</version></dependency>

源代码：  

package Aurora.test;import java.sql.Connection;import java.sql.DriverManager;import java.sql.ResultSet;import java.sql.SQLException;import java.sql.Statement;public class ConnectAurora {    public static void main(String[] args) {        // TODO Auto-generated method stub                        //声明Connection对象                        Connection con;                        String driver = "com.mysql.cj.jdbc.Driver";                        //URL指向要访问的数据库名mydata                        String url = "jdbc:mysql:// Aurora.example.rds.cn-northwest-1.amazonaws.com.cn:3306/db3";                        //MySQL配置时的用户名                        String user = "root";                        //MySQL配置时的密码                        String passWord = "root";                        //遍历查询结果集                        try {                            //加载驱动程序                            Class.forName(driver);                            //1.getConnection()方法，连接MySQL数据库！！                            con = DriverManager.getConnection(url,user,password);                            if(!con.isClosed())                                System.out.println("Succeeded connecting to the Database!");                            //2.创建statement类对象，用来执行SQL语句！！                            Statement statement = con.createStatement();                            //要执行的SQL语句                            String sql = "select * from fileindex";                            //3.ResultSet类，用来存放获取的结果集！！                            ResultSet rs = statement.executeQuery(sql);                            System.out.println("-----------------------------------------------------------------------------------------------");                                           System.out.println("------------------------------------------------------------------------------------------------");                              System.out.println("| "+ "id" + "\t" +" | "+ "app_id"+  "\t" +" | "+  "文件名字"+ "\t" +" | " + "文件地址"+ "\t" +" | ");                              System.out.println("------------------------------------------------------------------------------------------------");                                                      String APP_ID = null;                            String id = null;                            String address = null;                            String school = null;                            while(rs.next()){                                //获取stuname这列数据                                id = rs.getString("ID");                                //获取stuid这列数据                                APP_ID = rs.getString("APP_ID");                                address= rs.getString("File_Name");                                school=rs.getString("File_url");                                //输出结果                                System.out.println(" | "+id + "\t" +" | "+ APP_ID +" | "+ "\t" +" | "+address +" | "+ "\t" +" | "+school +" | " );                                System.out.println(" ------------------------------------------------------------------");                              }                            rs.close();                            con.close();                        } catch(ClassNotFoundException e) {                               //数据库驱动类异常处理                            System.out.println("Sorry,can`t find the Driver!");                               e.printStackTrace();                               } catch(SQLException e) {                            //数据库连接失败异常处理                            e.printStackTrace();                              }catch (Exception e) {                            // TODO: handle exception                            e.printStackTrace();                        }finally{                           System.out.println("数据库数据成功获取！");                        }                    }}
