以下是使用mysql-connector 連接Aurora for mysql：

Workbench 訪問(wèn)Aurora，跟mysql方式一致，如： Aurora.example.rds.cn-northwest-1.amazonaws.com.cn

用戶名：root

密碼：root

Eclipse 開(kāi)發(fā)首先在maven添加依賴，如下：  

    mysql
    mysql-connector-java
    8.0.15

源代碼：  

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
                        //聲明Connection對(duì)象
                        Connection con;
                        String driver = "com.mysql.cj.jdbc.Driver";
                        //URL指向要訪問(wèn)的數(shù)據(jù)庫(kù)名mydata
                        String url = "jdbc:mysql:// Aurora.example.rds.cn-northwest-1.amazonaws.com.cn:3306/db3";
                        //MySQL配置時(shí)的用戶名
                        String user = "root";
                        //MySQL配置時(shí)的密碼
                        String password = "root";
                        //遍歷查詢結(jié)果集
                        try {
                            //加載驅(qū)動(dòng)程序
                            Class.forName(driver);
                            //1.getConnection()方法，連接MySQL數(shù)據(jù)庫(kù)！！
                            con = DriverManager.getConnection(url,user,password);
                            if(!con.isClosed())
                                System.out.println("Succeeded connecting to the Database!");
                            //2.創(chuàng)建statement類(lèi)對(duì)象，用來(lái)執(zhí)行SQL語(yǔ)句！！
                            Statement statement = con.createStatement();
                            //要執(zhí)行的SQL語(yǔ)句
                            String sql = "select * from fileindex";
                            //3.ResultSet類(lèi)，用來(lái)存放獲取的結(jié)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()){

                                System.out.println(" | "+id + "\t" +" | "+ APP_ID +" | "+ "\t" +" | "+address +" | "+ "\t" +" | "+school +" | " );
                                System.out.println(" ------------------------------------------------------------------");  
                            }
                            rs.close();
                            con.close();
                        } catch(ClassNotFoundException e) {   
                            //數(shù)據(jù)庫(kù)驅(qū)動(dòng)類(lèi)異常處理
                            System.out.println("Sorry,can`t find the Driver!");   
                            e.printStackTrace();   
                            } catch(SQLException e) {
                            //數(shù)據(jù)庫(kù)連接失敗異常處理
                            e.printStackTrace();
