pip install awscli 命令行環境java
安裝好後 輸入 aws 測試 是否安裝成功json
在鍵入 aws configure 進行配置windows
AWS Access Key ID[None]:1oracle
AWS Secret Access Key [None]:1app
Default region name [None]:1ide
Default output format[None]:1測試
以上配置 能夠參考 dynamodb 官方文檔 ui
dynamodb windows 安裝包下載地址:url

java 運行環境 JRE 下載地址:
https://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
下載對應的jre 版本
安裝完後,須要添加環境變量
DynamoDB 的啓動 awscli 環境
java -Djava.library.path=./dynamodb_local_latest-jar DynamoDBLocal.jar -sharedDb
Windows PowerShell 運行:window 命令行
cd dynamodb_local_latest
java -D"java.library.path=./dynamodb_local_latest" -jar DynamoDBLocal.jar
輸入後 不要關閉 運行窗口
