Maven将applicationContext.xml从src / main / resources复制到target / myproject / WEB-INF(Maven copying applicationContext.xml from src/main/resources to target/myproject/WEB-INF)

 基于其他答案，下面是一种使用软锁API来防止节点同时进入涉及两种状态的事务的方法： 
 
@InitiatingFlow
@StartableByRPC
class AtomicFlow(val stateRefToSpend: StateRef, val stateRefToLock: StateRef) : FlowLogic<Unit>() {
    @Suspendable
    override fun call() {
        try {
            serviceHub.vaultService.softLockReserve(runId.uuid, NonEmptySet.of(stateRefToSpend, stateRefToLock))
        } catch (e: StatesNotAvailableException) {
            logger.error("A transaction is already underway using S2.")
            return
        }

        val stateToSpend = serviceHub.loadState(stateRefToSpend)

        // Continue with transaction...
    }
}

Building on the other answers, here's one way of using the soft-locking API to prevent a node from entering into transactions involving both states at once:
 
@InitiatingFlow
@StartableByRPC
class AtomicFlow(val stateRefToSpend: StateRef, val stateRefToLock: StateRef) : FlowLogic<Unit>() {
    @Suspendable
    override fun call() {
        try {
            serviceHub.vaultService.softLockReserve(runId.uuid, NonEmptySet.of(stateRefToSpend, stateRefToLock))
        } catch (e: StatesNotAvailableException) {
            logger.error("A transaction is already underway using S2.")
            return
        }

        val stateToSpend = serviceHub.loadState(stateRefToSpend)

        // Continue with transaction...
    }
}
