已经解决， 问题原因：调用send方法会取Response body内容 cn.think.in.java.impl.DefaultNode.ElectionTask image 问题解决： 在异步取值，直接转换为body对象即可 image

还遇到一些问题，是对象没有实现序列化接口，把entity包下面的实体实现序列化接口即可

您好，我在测试领导选举的时候，总是收到 2023-01-28 17:46:56,500 Raft thread ERROR [cn.think.in.java.impl.DefaultNode:lambda$run$2:581] - ElectionTask RPC Fail , URL : localhost:8779 2023-01-28 17:46:56,500 Raft thread ERROR [cn.think.in.java.impl.DefaultNode:lambda$run$2:581] - ElectionTask RPC Fail , URL : localhost:8776 2023-01-28 17:46:56,500 Raft thread ERROR [cn.think.in.java.impl.DefaultNode:lambda$run$2:581] - ElectionTask RPC Fail , URL : localhost:8777 2023-01-28 17:46:56,500 Raft thread ERROR [cn.think.in.java.impl.DefaultNode:lambda$run$2:581] - ElectionTask RPC Fail , URL : localhost:8778 2023-01-28 17:46:56,500 Raft thread INFO [cn.think.in.java.impl.DefaultNode:run:631] - node Peer{addr='localhost:8775'} maybe become leader , success count = 0 , status : CANDIDATE

能请教下您有遇到这个问题吗？是如何解决的？

问题已经解决，确实是entity包下面的实体没有实现序列化接口的问题，感谢 @xiedi-w

在验证日志复制的时候，在客户端的get和put方法同样存在类型转换异常，求如何解决

我也遇到了这个问题，请问您将实体实现序列化接口后就可以了吗？
