我正在使用CordaRPCClient作为Corde Node的中间件来构建Spring Boot Web服务器。从节点查询当前时间可以正常工作。但是在打电话时
设置matchingParties = CordaClient.getInstance（）。proxy.partiesFromName（“ PartyB”，false）;
我正在获取以下堆栈跟踪：
com.esotericsoftware.kryo.KryoException: java.lang.ClassCastException: org.bouncycastle.asn1.DLSequence cannot be cast to org.bouncycastle.asn1.ASN1Integer
Serialization trace:

任何人都可以看到该问题，并告诉我如何解决吗？
答案 0 :(得分：0)
众所周知，这是由RPC客户端使用的Corda版本与节点使用的Corda版本之间的差异引起的。如果两者都使用相同版本的Corda，则应该可以使用。
