Corda 和 Corda Enterprise 节点交互时出现序列化方案错误

问题描述 投票：0回答：1

我有一个包含两个节点的网络：

  • NodeA
    运行 Corda Enterprise 3
  • NodeB
    运行 Corda（开源）3

当 

NodeA
使用 Corda Finance CorDapp 将现金转移到 
NodeB
时，我会收到 
Serialization scheme not supported.
形式的例外情况。

如果 Finance CorDapp 是针对 Corda Enterprise 3.2 编译的，我会得到以下堆栈跟踪：

如何解决这个问题？

这是 Corda 3 中的一个错误，其中：

  • 针对 Corda Enterprise 3 编译的 CorDapp 无法在 Corda 3 节点上运行
  • 针对 Corda 3 编译的 CorDapp 无法在 Corda Enterprise 3 节点上运行

这是因为 Corda 3 使用 Kryo 进行 RPC，而 Corda Enterprise 3 使用 AMQP 进行 RPC。

有两种解决方法：

  • 编译 CorDapp 两次 - 一次用于 Corda 3 节点，一次用于 Corda Enterprise 3 节点
  • 升级到 Corda 4
