无法使用非基于lagom的静态项目服务与service-locator-dns库

提问于

我们成功地将“service-locator-dns”集成到Lagom并部署在Kubernetes中,Lagom项目中的所有服务都通过Kubernetes SRV请求正确解决 .

但即使是静态定义的(在build.sbt中)非lagom项目也会经历 name-translatorssrv-translators ,最终无法解决 .

我在Github中提出了相同的问题https://github.com/lightbend/service-locator-dns/issues/29

我们可以通过名称翻译器本身的变化来避免这种情况,还是我们需要进行任何额外的更改?

如果您提供支持或参考任何文档,它将对我们非常有帮助 .

服务特质

trait PremiumCalculator extends Service {
  def getPremiums(channelName: String): ServiceCall[JsValue, JsValue]
  override final def descriptor = {
    import Service._
    named("premium-calculator")
      .withCalls(
        restCall(Method.POST, "/api/v2/premium/:channelName", getPremiums _))
      .withAutoAcl(true)
  }
}

在build.sbt中

lagomUnmanagedServices in ThisBuild := Map(
  "premium-calculator" -> "https://test.in",
)

    要在Kubernetes的Lagom中找到非Lagom /第三方服务,我们必须使用Lagom的服务定位器 . 像这样:

    lagom.services {
      "premium-calculator" = "https://test.in"
    }
    

    此外,我们必须使用 ConfigurationServiceLocator 来定位服务:

    if(environment.isProd()) {
      bind(ServiceLocator.class).to(ConfigurationServiceLocator.class);
    }
    

    这里 ConfigurationServiceLocator 通过配置定位服务(顾名思义) .

    我希望这有帮助!
