無法加載AWS憑證使用java訪問dynamoDB（本地）時發生錯誤

我已經安裝了本地版本的dynamoDB，並設置了一個Maven Java項目來訪問數據庫。當我運行代碼時，出現以下錯誤。由於我已經在本地安裝服務器（它運行兒子localhost：8000），我沒有任何憑據提供... 任何想法如何解決它？無法加載AWS憑證使用java訪問dynamoDB（本地）時發生錯誤

       System.out.println(table.getTableName());

}

在這種迷迷糊糊的時候我正在尋找同樣的問題。經過半天的浪費，設法解決了這個問題。在這裏發帖，以防有人再次遇到這種情況。

而最糟糕的是？我需要經過數千頁的解決方案才能實現這個解決方案，並希望能夠獲得關於該問題的一些信息。至少，文檔應該提到一些注意事項！

解決辦法：

Configuring AWS Credentials：去通過建立一些憑證。將其配置爲任何隨機事物，這並不重要。

是的，這是它！

對於那些PPL誰仍然懶惰（像我一樣;-)）要經過，只要按照最簡單的方法：

打開默認的配置文件：~/aws/credentials

變化它的任何值（喜歡這裏空字符串）

[default] 
aws_access_key_id='' 
aws_secret_access_key=''

運行程序。您可以稍後感謝我：D
