    这是不可能的,但不是因为原因 manish 如上所述。

    从Corda 3开始,将交易发送给监管机构进行签署将导致 java.io.NotSerializableException

    这种行为是有意义的——在看不到输入和输出状态的事务上签名的目的是什么?如果您确实希望提供签名,则可以通过发送 FilteredTransaction 如果所有的状态都被过滤掉了,以及监管机构没有的任何其他组件的类定义。然后使用 serviceHub.createSignatures(filteredTransaction) .

    注:这里是一个例子,我收到的stacktrace时,我试图发送一个交易对手 SignedTransaction 对于没有类定义的组件:
