根据我的 Corda 项目，我正在运行一个相当大的 Spring 版本（生成 jHipster）。运行 spring 服务器时，我遇到了一些与类星体相关的错误。我猜这是因为 quasar-utils 在服务器的 gradle 依赖项中。Quasar 正在抱怨与 OAuth2 春季服务相关的事情。到目前为止，我实际上没有使用任何 OAuth 功能，所以我不确定这些错误是否是良性的。无论如何，我有点担心类星体的干扰。有没有办法在服务器 gradle 依赖项中没有 quasar-utils 的情况下与 Corda 进行 RPC 交互？

以下是错误：

只要您不使用任何 Quasar 无法在内部流中检测的对象，您就不会遇到任何问题。Quasar 主要在 Corda 中用于可悬挂的纤维，这意味着一个序列化的堆栈。如果该对象不存在于所述堆栈上，则不应引起任何问题。

但更重要的是；您的 Corda 节点和 Spring Boot 应用程序应该在不同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 Boot 应用程序是独立的，那么我建议将其构建在一个单独的 gradle/maven 子项目中，而不依赖于 quasar-utils。

派对有点晚了，但是看看quasar-utils 这里的源代码，你可以在根构建中为被忽略的包设置一个扩展属性：

ext.quasar_exclusions = [
        'co.paralleluniverse**',
        'groovy**',
        'com.esotericsoftware.**',
        'jdk**',
        'junit**',
        'kotlin**',
        'net.rubygrapefruit.**',
        'org.gradle.**',
        'org.apache.**',
        'org.jacoco.**',
        'org.junit**',
        'org.slf4j**',
        'worker.org.gradle.**',
        'com.nhaarman.mockito_kotlin**',
        'org.assertj**',
        'org.hamcrest**',
        'org.mockito**',
        'org.opentest4j**',
        'org.springframework**',
        'reactor.core.publisher**',
        'com.github.manosbatsis.corbeans.spring.boot**'
]

此外，4.0.45 版似乎允许quasar扩展，例如：

quasar {
    /// ...
    // defaults to quasar_exclusions property
    excludePackages = [
        'glob for package not to be instrumented',
        //...
    ]
}
