如何在 Spring 启动应用程序中注入普罗米修斯度量 bean?

Question

我有一些类，我想将 Prometheus Config 中的 bean 作为构造函数参数注入其中。

@Component
class Foo(
private val counterMetric: Metric
) {
}
@Component
class Bar(
private val counterMetric: Metric
) {
}

@Configuration
class PrometheusConfig {
@Bean
fun counterMetric() = Counter.build()
.name("invite_requests")
.help("Number of invite requests")
.labelNames("method")
.register()
}

我无法注入这个豆子，因为 Spring Boot 有@PrometheusMetricsExportAutoConfiguration注释。我该如何处理？

已经注册了PrometheusConfig类，请重命名为其他名称，例如PrometheusConfiguration.
