Apache Dubbo Component

Java SDK (apache/dubbo)

Dubbo Version

Dubbo:3.3.2 JDK: 21 k8s: 1.23.6

Steps to reproduce this issue

dubbo3 registered to k8s, set the weights of v1 and v2 provider, but the consumer call provider has no effect

What you expected to happen

Both dubbo consumer and provider have been registered in k8s, VirtualService and DestinationRule have been added to the provider for weighting, the yaml of the provider in k8s is as follows, provider yaml

apiVersion: networking.istio.io/v1alpha3
kind: DestinationRule
metadata:
  name: k8s-provider-rule
spec:
  host: k8s-provider-svc
  trafficPolicy:
    loadBalancer:
      simple: ROUND_ROBIN
  subsets:
    - name: v1
      labels:
        version: v1
    - name: v2
      labels:
        version: v2
---
apiVersion: networking.istio.io/v1alpha3
kind: VirtualService
metadata:
  name: k8s-provider-vs
  namespace: dubbo-app
spec:
  hosts:
    - k8s-provider-svc
  tcp:
    - route:
        - destination:
            host: k8s-provider-svc
            subset: v1
          weight: 9999
        - destination:
            host: k8s-provider-svc
            subset: v2
          weight: 1

consumer yaml

apiVersion: v1
kind: Service
metadata:
  name: k8s-consumer-svc
  namespace: dubbo-app
spec:
  type: ClusterIP
  sessionAffinity: None
  selector:
    app: k8s-consumer
  ports:
    - protocol: TCP
      port: 8811
      targetPort: 8811
      name: tcp
    - name: grpc-tri
      protocol: TCP
      port: 50052
      targetPort: 50052

the consumer code

··· @DubboReference(version = "1.0.0", retries = 0, providedBy = "k8s-provider-svc", timeout=5000, providerPort = 50052, check = false, cluster="failsafe", protocol = "tri",mock = "org.example.k8s.api.service.mock.ApiOrderMock") ApiOrder apiOrder; ···

Consumer tries to add loadbalance = “roundrobin” but it still affects Istio weights

@DubboReference(version = "1.0.0",
            retries = 0,
            providedBy = "k8s-provider-svc",
            timeout=5000,
            providerPort = 50052,
            loadbalance = "roundrobin",
            check = false,
            cluster="failsafe",
            protocol = "tri",mock = "org.example.k8s.api.service.mock.ApiOrderMock")
    ApiOrder apiOrder;

check the lastest dubbo codes because PRs was not backported to 3.2 anymore.
