根据我的Corda项目，我正在运行一个非常大的Spring版本（jHipster生成） . 当我运行spring服务器时，我得到了一些类星体相关的错误 . 我猜这是因为quasar-utils是服务器的gradle依赖项 . Quasar抱怨与OAuth2 spring服务有关的事情 . 到目前为止，我实际上并没有使用任何OAuth功能，所以我不确定这些错误是否是良性的 . 无论如何，我有点担心一般的类星体干扰 . 有没有办法与Corda进行RPC交互而不在服务器gradle依赖项中使用quasar-utils？
以下是错误：

只要您没有使用Quasar无法检测内部流量的任何对象，您就不会遇到任何问题 . Quasar主要用于Corda中的可悬挂纤维，这意味着序列化堆栈 . 如果所述堆栈上不存在该对象，则不应导致任何问题 .
但更重要的是;您的Corda节点和Spring Boot应用程序应在单独的进程中运行，以避免任何干扰 . 在编译Cordapps和Corda本身时，您只需要Quasar utils . 如果您的Spring启动应用程序是独立的，那么我建议在单独的gradle / maven子项目中构建它，而不依赖于quasar-utils .
