Java AWS Lambda错误加载类

我是亚马逊网络服务的新手 . 我创建了一个lambda函数，但是当我从亚马逊控制台运行它时，我收到以下错误：

加载类的错误com.aws.codestar.projecttemplates.handler.UserHandler：com / amazonaws / services / dynamodbv2 / AmazonDynamoDB：class java.lang.NoClassDefFoundError java.lang.NoClassDefFoundError：com / amazonaws / services / dynamodbv2 / AmazonDynamoDB at java . java.lang.Class.forName（Class.java:348）中的lang.Class.forName0（本机方法）由java.net.URLClassLoader.findClass引起的：java.lang.ClassNotFoundException：com.amazonaws.services.dynamodbv2.AmazonDynamoDB （URLClassLoader.java:381）java.lang.ClassLoader.loadClass（ClassLoader.java:424）java.lang.ClassLoader.loadClass（ClassLoader.java:357）... 2更多

如何解决问题？
