我创建了一个用java中的Achilles Object映射编写的Cassandra客户端(使用IntelliJ + Gradle).我的客户端在IntelliJ中本地工作正常,但在docker容器中部署时抛出异常.我目前在我的docker容器中遇到以下异常.
java.lang.NoClassDefFoundError:无法在com.datastax.driver.core.NettyOptions.afterBootstrapInitialized(NettyOptions.java:144)com.datastax.driver.core.Connection $ Factory.newBootstrap初始化类io.netty.buffer.PooledByteBufAllocator.

但是,io.netty.buffer.PooledByteBufAllocator作为其中
netty-buffer-4.0.56.Final.jar一部分的类已经是类路径的一部分.
当我尝试从我的Intellij IDE本地测试东西时,一切正常.但是在部署之后,我在我的docker容器中遇到了这个问题.
该服务在我的docker容器中启动,如下所示:
