我在：https://github.com/marcelalburg/aws-dynamodb-local

创建了一个示例项目

如果你运行mvn spring-boot：运行你得到这个例外：

非常感谢

Answer 1

这可能是由于Java Library Path问题，对我来说，在我在IDE中添加以下系统属性后它开始工作

-Djava.library.path=C:\Setups\sqlite4java-392

我必须从这个位置下载并提取sqlite4java - https://bitbucket.org/almworks/sqlite4java

我相信这也可以在构建系统中以编程方式设置。如果Amazon DynamoDB提供了更合适的错误，情况会好得多。

Answer 2

我到sqlite4的路径也有同样的错误。路径中有一个空格，该空格已转换为％20，这导致这两行无法按计划进行。

val sqliteLibPath = getClass.getClassLoader.getResource("./lib").getPath
System.setProperty("sqlite4java.library.path", sqliteLibPath)

使用Maven和Java8的Amazon DynamoDb Local
