在驱动程序(NodeDriver.kt)创建的本地网络上运行流时，Corda服务不存在 [英] Corda service does not exist when running flow on local network created by driver (NodeDriver.kt)

问题描述

在cordapp流程中访问服务时出现以下异常

I am getting following exception when accessing a service in flow of a cordapp

java.lang.IllegalArgumentException:Corda服务com.example.services.MyService不存在

java.lang.IllegalArgumentException: Corda service com.example.services.MyService does not exist

我正在使用cordaV2，并尝试使用

i am using cordaV2 and have tried to edit NodeDriver.kt with

driver(isDebug = true，extraCordappPackagesToScan =listOf("com.example.services"))

driver(isDebug = true, extraCordappPackagesToScan = listOf("com.example.services"))

但这没有帮助.

如何更新在NodeDriver.kt创建的网络上本地运行的cordApp代码，并且不会引发此异常！

How can i update cordApp code that it runs locally on network created from NodeDriver.kt and it doesn't throw this exception!

推荐答案

我重新检查了代码，发现我没有在服务类中使用ServiceHub参数.添加后，它是固定的.

I rechecked my code and realized i wasn't using ServiceHub parameter in my service class. After adding that it was fixed.

MyService类( val服务:ServiceHub ):SingletonSerializeAsToken()

class MyService(val services: ServiceHub) : SingletonSerializeAsToken()
