adservice-springcloud

This repo re-implements opentelemetry-demo-webstore's adservice with nacos registry and sentinel.

integrate list

• nacos
• sentinel

curl

grpcurl -plaintext -d '{"context_keys": ["binoculars","telescopes"]}' localhost:8080 hipstershop.AdService/GetAds

metrics

adservice-springcloud will emit two metrics:

Name	Description	Unit	Type
adservice_grpc_call_total	record grpc call totals	N/A	Counter
adservice_grpc_duration_seconds_bucket	record grpc call latency	ms	histogram

mock latency

the hipstershop.AdService/GetAds API will do a matrix calculation internally, you can use -Dspring.matrixRow=200 to specific the matrix size

mock error

the hipstershop.AdService/GetAds API will return error randomly(50%), you can use -Dspring.randomError=false to disable this feature.

Integrate to Nacos and Sentinel

• Please notes the bootstrap.yml file:

  adservice/src/main/resources/bootstrap.yml
  

• Make sure your Dockerfile has: JAVA_OPTS env:

  $JAVA_OPTS -jar /bin/xxx.jar
