src/main/resources/elasticapm.properties
server_url=${PROJECT_ELASTICAPM_URL}

当服务器 url 作为 ENV 参数传递给 docker 启动的服务时，elasticapm.properties 中的环境变量不会在运行时解析。而是抛出以下错误

ch.client.WIRE       : [7f640f1e] Received raw response: 200 OK

您可以通过直接server_url为变量提供值来提供 via 环境变量的值ELASTIC_APM_SERVER_URL。例如：

environment:
  - ELASTIC_APM_SERVICE_NAME=backend-java
  - ELASTIC_APM_SERVER_URL=http://apm-server:8200
  - ELASTIC_APM_APPLICATION_PACKAGES=com.riferrei.backend.*
