我如何让 AmazonDynamoDB Local 的用户为我工作。尽管提供了所有配置信息，但我在服务器端和客户端超时时遇到错误。

您需要运行 java 命令，以便-Djava.library.path引用您提取本地 DynamoDB 包的路径。.in表示“-Djava.library.path=.当前目录”，应用程序需要能够加载本地 DynamoDB 目录中的原生 SQLite 库。

因此，您可以从本地 DynamoDB 目录中运行此命令：

java -Djava.library.path=. -jar DynamoDBLocal.jar

或者您必须提供两者的完整路径：

java -Djava.library.path=c:\path\to\dynamodb\ -jar c:\path\to\dynamodb\DynamoDBLocal.jar

试试这个 Maven 插件，它为你做了这一切：http ://www.jcabi.com/jcabi-dynamodb-maven-plugin/index.html

我知道这是一个旧请求，但从那时起我开始使用其他解决方案，例如 localstack。我建议工程师使用localstack。它可以通过调用 docker 来运行！
