我正在使用带区域约束的开放源代码运行的帐户测试Corda 4.3。
我有4个节点，分别是Node A，Node B，Node C和Notary（Notary是Corda 4.1的CE版本），并使用PostgreSQL作为数据库。
首先，我在节点A上创建一个帐户 testadm1 并与节点B共享
然后我在节点B上创建一个帐户 seller1 和 seller2 并与节点A共享
使用以下流程
CreateAccountFlow
@StartableByRPC
@StartableByService
@InitiatingFlow
class CreateNewAccount(private val acctName:String) : FlowLogic<String>() {
@Suspendable
override fun call(): String {
//Create a new account
val newAccount = accountService.createAccount(name = acctName).toCompletableFuture().getOrThrow()
val acct = newAccount.state.data
return ""+acct.name + " team's account was created. UUID is : " + acct.identifier
}
}
ShareAccountFlow
@StartableByRPC
@StartableByService
@InitiatingFlow
class ShareAccountTo(private val acctNameShared: String,
private val shareTo: Party) : FlowLogic<String>(){
@Suspendable
override fun call(): String {
//Create a new account
val allmyAccounts = accountService.ourAccounts()
val sharedAccount = allmyAccounts.single { it.state.data.name == acctNameShared }.state.data.identifier.id
accountService.shareAccountInfoWithParty(sharedAccount,shareTo)
return "Shared " + acctNameShared + " with " + shareTo.name.organisation
}
}
然后我尝试使用以下流程从节点A上的testadm1帐户向节点B上的Seller1帐户发行StateA：
object IssueStateA {
@InitiatingFlow
@StartableByRPC
class Initiator(private val documentNumber: String,
private val amount: BigDecimal,
private val whoAmI: String,
private val whereTo: String) : FlowLogic<SignedTransaction>() {
private lateinit var myKey: PublicKey
private lateinit var myAnonymousParty: AnonymousParty
private lateinit var targetAcctAnonymousParty: AnonymousParty
@Suspendable
override fun call(): SignedTransaction {
logger.info("IssueStateA whoAmI: $whoAmI")
val myAccount = accountService.accountInfo(whoAmI).single().state.data
logger.info("IssueStateA myAccount: $myAccount")
myKey = subFlow(NewKeyForAccount(myAccount.identifier.id)).owningKey
logger.info("IssueStateA myKey: $myKey")
myAnonymousParty = AnonymousParty(myKey)
logger.info("IssueStateA myAnonymousParty: $myAnonymousParty")
logger.info("IssueStateA whereTo: $whereTo")
val targetAccount = accountService.accountInfo(whereTo).single().state.data
logger.info("IssueStateA targetAccount: $targetAccount")
targetAcctAnonymousParty = subFlow(RequestKeyForAccount(targetAccount))
logger.info("IssueStateA targetAcctAnonymousParty: $targetAcctAnonymousParty")
val (stx, sessions) = collectSignature(verifyAndSign(build()))
return subFlow(FinalityFlow(stx, sessions))
}
private fun build(): TransactionBuilder {
val stateOut = StateA(
buyer = myAnonymousParty,
documentNumber = documentNumber,
lifecycle = StateAContract.Lifecycle.ISSUED,
seller = targetAcctAnonymousParty,
amount = amount
)
val result = TransactionBuilder(firstNotary).apply {
// Add outputs
withItems(StateAndContract(stateOut, StateAContract.CONTRACT_ID))
// Add commands
addCommand(StateAContract.Commands.Test(), listOf(targetAcctAnonymousParty.owningKey, myKey))
}
return result.toLedgerTransaction(serviceHub)
}
private fun verifyAndSign(transaction: TransactionBuilder): SignedTransaction {
transaction.verify(serviceHub)
return serviceHub.signInitialTransaction(transaction)
}
@Suspendable
private fun collectSignature(transaction: SignedTransaction): Pair<SignedTransaction, Set<FlowSession>> {
val sessions = transaction.sessionsOfParticipants()
return subFlow(CollectSignaturesFlow(
transaction,
sessions,
listOf(ourIdentity.owningKey, myKey))) to sessions
}
}
@InitiatedBy(Initiator::class)
class Responder(private val otherFlow: FlowSession) : FlowLogic<SignedTransaction>() {
@Suspendable
override fun call(): SignedTransaction {
return subFlow(ReceiveFinalityFlow(otherFlow))
}
}
}
我得到了这个错误

这是StateA的样子
@BelongsToContract(StateAContract::class)
data class StateA(
val buyer: AnonymousParty,
val documentNumber: String,
val issuedDate: Instant = Instant.now(),
val lifecycle: StateAContract.Lifecycle,
val seller: AnonymousParty,
val amount: BigDecimal,
override val linearId: UniqueIdentifier = UniqueIdentifier()) : LinearState, QueryableState {
override val participants: List<AbstractParty> get() = listOf(buyer, seller)
override fun supportedSchemas(): Iterable<MappedSchema> = listOf(StateASchema)
override fun generateMappedObject(schema: MappedSchema): PersistentState {
if (schema is StateASchema) {
return StateASchema.StateAEntity(
buyer = buyer,
documentNumber = documentNumber,
issuedDate = issuedDate,
lifecycle = lifecycle.toString(),
seller = seller,
amount = amount.quantity
)
} else {
throw IllegalStateException("Cannot construct instance of ${this.javaClass} from Schema: $schema")
}
}
}
这是Schema类
object StateSchema
object StateASchema : MappedSchema(
schemaFamily = StateSchema::class.java,
version = 1,
mappedTypes = listOf(StateA::class.java)
)
@Entity
@Table(name = "stateA")
data class StateAEntity(
@Column(name = "linear_id")
var linearId: String? = null,
@Column(name = "buyer")
val buyer: AbstractParty? = null,
@Column(name = "external_id")
var documentNumber: String? = null,
@Column(name = "issued_date")
var issuedDate: Instant? = null,
@Column(name = "seller")
val seller: AbstractParty? = null,
@Column(name = "amount")
val amount: BigDecimal? = null
) : PersistentState()
我已经检查了我的postgres数据库，并使用此sql在帐户表中看到节点A具有节点B的帐户
select * from accounts
join vault_states
on vault_states.transaction_id = accounts.transaction_id
and vault_states.output_index = accounts.output_index
and vault_states.state_status = 0
我做错了什么还是我错过了什么？

我找到了根本原因
首先，我以Corda 4.1版启动该节点，并创建具有3列 external_id，public_key_hash 和 id （不为null）
的表pk_hash_to_ext_id_map表但是我不对数据库做任何事情就将Corda版本更改为4.3。我认为在4.3中，它不再需要 id ，因此当它尝试放入数据库时，它会将id发送为null。
所以我要做的是清除数据库并重新启动所有节点，现在重新启动带有2列 external_id，public_key_hash 的pk_hash_to_ext_id_map表，

我怀疑这是您的generateMappedObject函数。我认为您不希望返回StateA，因为它不是PersistentState。您可以创建一个PersistentState并返回它吗？
