无法在service-locator-dns库中使用基于非基于lagom的静态项目服务

Question

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（在build.sbt中）非拉格姆项目也会通过name-translators和srv-translators，最后无法解决。

我在Github https://github.com/lightbend/service-locator-dns/issues/29提出了同样的问题

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。

服务热线

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",
)

Answer 1

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！
