AWS S3 KMS Java：提供属性文件 MultiLangDaemon

Question

我想创建一个示例代码来将加密文件上传和下载到 AWS S3。 当我尝试运行代码时，出现以下错误：

您必须提供一个属性文件java com.amazonaws.services.kinesis.multilang.MultiLangDaemon

我不知道，为什么这里会影响运动。 即使我在项目目录中创建了一个名为 config.properties 的文件，它也无法识别。

我的代码：

我是一个绝对的初学者。 因此，如果您对代码有其他改进（除了错误的修复），请告诉我。 提前致谢！

你得到的错误是由于JDK中的一些变化，你必须将JDK--version升级到11或更新的更新版本，jdk-8不能支持一些新功能。 必须添加以下依赖项：

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.33</version>
</dependency>

<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.33</version>
</dependency>
