Answer 1

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 目录中的本机 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

智能

如果您在 IntellJ 中运行配置，则可以使用对话框“编辑配置”| “添加 jar”。修改选项 | 修改 classpath，并添加 jar 的路径。
