Corda 4.0：如何检索旧 CorDapp 执行的交易？

时间：2021-05-09 03:42:49

标签： spring-boot corda

我们正在使用 Corda 4.0 和 Springboot Web 服务器构建 POC。

以下是用于构建 POC 的 Corda 平台、Springboot 服务器和其他基本依赖项的版本-

cordaReleaseGroup=net.corda
cordaVersion=4.0
gradlePluginsVersion=4.0.45
kotlinVersion=1.2.71
junitVersion=4.12
quasarVersion=0.7.10
spring_version = '4.3.11.RELEASE'
spring_boot_version = '2.0.2.RELEASE'
spring_boot_gradle_plugin_version = '2.1.1.RELEASE'
jvmTarget = "1.8"
log4jVersion =2.11.2
platformVersion=4
slf4jVersion=1.7.25
nettyVersion=4.1.22.Final

为POC开发的CorDapp有四个节点-

Notary Node
Provider Company Node
Consumer Company 1 Node
Consumer Company 1 Sub Contact Node

在节点数据库中，上述节点之间有 10 个交易流。

后来由于新的需求，新的字段被添加到事务架构中，Cordapp 被重新创建并分发到节点。

当 Web 应用程序运行时，我无法查看 10 个事务。

节点抛出以下错误：

问题： 是否可以检索具有旧架构的事务？请指导

更新

我正在使用以下代码从保管库中检索记录：

val vaultStatesAndRefs = services.proxy.vaultQueryBy<State>().states
val vaultStates = vaultStatesAndRefs.map { it.state.data }
resultset = vaultStates.map { it.toJson() }.toString()

1 个答案:

答案 0 :(得分：0)

一些建议：

您如何运行架构查询？我好像没有在这里看到。

如果您仍在构建 Corda 4，请注意 Corda 5 将于今年晚些时候发布，而我们目前使用的是 4.8，因此可能值得尝试升级。

如果您正在寻找有关构建应用程序和更新依赖项的指南，请查看 cordapp 模板：https://github.com/corda/cordapp-template-kotlin

现在就如何查询而言，您可能想在流中查询您的架构，看看它是否以您期望的方式存储？

你应该能够在你的流程中加入这样的东西（假设它是一个线性状态）

            List<UUID> listOfLinearIds = Arrays.asList(stateLinearId.getId());
            QueryCriteria queryCriteria = new QueryCriteria.LinearStateQueryCriteria(null, listOfLinearIds);
            Vault.Page results = getServiceHub().getVaultService().queryBy(IOUState.class, queryCriteria);
            StateAndRef inputStateAndRefToSettle = (StateAndRef) results.getStates().get(0);
            IOUState inputStateToSettle = (IOUState) ((StateAndRef) results.getStates().get(0)).getState().getData();
