我已下载AWS dynamodb zip文件并解压缩到D：/ dynamoDB文件夹尝试使用

通过命令提示符运行时

java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar

发生以下异常

我在Windows 32系统中使用Java7 sdk。

Answer 1

如果应用程序试图访问或修改对象的指定字段，并且该对象不再具有该字段，则抛出

NoSuchFieldError个异常“。在这种情况下，可能是jar是针对一个版本的java（或其他依赖项）编译的，并且您使用的是不兼容的不同版本。

我建议自support for Java7 ended as of April 2015以来更新到Java8。另外，检查您的jetty版本（因为JVM之外的最后一次调用是由org.eclipse.jetty.util.DateCache.<init>(DateCache.java:88)引起的），以确保它兼容。
