我现在有点迷路了。我建立了一个 Kubernetes 集群,部署了一个 Spring Boot API 和一个运行良好的 LoadBalancer。现在我想在 LoadBalancer 上启用代理协议以保留真实的客户端 IP,但是一旦我这样做了,我的 Spring Boot API 总是返回一个400 Bad Request
并IllegalArgumentException
抛出一个。
这是简短的堆栈跟踪(我屏蔽了 IP 地址):

我正在使用 Hetzner 的hcloud-cloud-controller-manager。
这是我的负载平衡器:
apiVersion: v1
kind: Service
metadata:
labels:
service: auth-service
name: auth-service-service
annotations:
load-balancer.hetzner.cloud/name: "lb-backend"
load-balancer.hetzner.cloud/health-check-port: "80"
load-balancer.hetzner.cloud/uses-proxyprotocol: "true"
spec:
ports:
- name: http
port: 80
targetPort: 8080
selector:
service: auth-service
externalTrafficPolicy: Local
type: LoadBalancer
这是我的弹簧配置:

driver-class-name: org.postgresql.Driver
flyway:

您可能已经注意到,我已经尝试基于此问题启用前向标头。
谢谢你的帮助!
