corda - Corda4 上的 Corda Settler

问题描述

我将 Corda-Settler 升级到 Corda 4 版本，并添加了波纹库ripple-core 和ripple-bouncycastle，以使其独立于本地安装。部署节点时，出现以下错误：

我既没有触及 oracle 的构建文件，也没有触及相应的类或 xrp.conf。我很感激任何帮助！提前谢谢了！

解决方案

这是我的解决方案：在com.r3.corda.finance.obligation.oracle.services.XrpOracleService代码的小改动是必要的，ClassLoader 的添加起到了神奇的作用

private val nodes by lazy { ConfigFactory.parseResources(javaClass.getClassLoader(), configFileName).getStringList("nodes").mapNotNull(::URI) }
+    //private val nodes by lazy { ConfigFactory.parseResources(configFileName).getStringList("nodes").mapNotNull(::URI) }
