在 lambda aws 测试期间,抛出 class not found 异常
During lambda aws test, a class not found exception is thrown
Serverless Functions with Spring Cloud Functions 是我使用的 Baeldung 文章。我更改了他们推荐的 aws-adapter 依赖项,因为在 maven 中导入失败,所以我找到了版本 3.0.1.RELEASE 并改用它。所有错误都消失了,我将项目上传为 .jar 文件。我尝试了 "maven package" 和 "maven clean shade" 命令来创建一个 .jar 文件并直接上传到 lambda 函数。我按照他们的说明在 lambda 函数中指定处理程序。有谁知道我可能 运行 陷入这个问题的任何其他原因。

您似乎同时使用了一些混合且不兼容的函数版本 1.0.1.RELEASE 和 3.0.1.RELEASE 尽管您的问题可能无关紧要,但如果没有看到您的代码就无法判断。
好消息是:
对于 3.0.1 版本,我们只是添加了一个 Getting Started guide which takes you step by step. We've also updated the example,它也在入门中引用。有了它,您应该会在 5-10 分钟内起床 运行。
