How to use

configure kubernetes

Spring Cloud Kubernetes use Fabric8 Kubernetes Java Client to call Kubernetes API. So you can use settings from different sources. For example, I copy my Kubernetes Cluster's Kube config file to .kube directory which is under os user root directory

configure dev environment

Create a kubernetes namespace named wm-test which is defined in bootstrap.yml. Then you can create a Kubernetes ConfigMap to externalize the parameters to pass to cn4j like application-{profile}.yaml.

kind: ConfigMap
apiVersion: v1
metadata:
  name: gateway-dev
  namespace: wm-test
data:
  application.yml: |-
    backend-service-alias: ''
    spring:
      profiles: dev
      cloud:
        kubernetes:
          discovery:
            enabled: false 
        gateway: 
          routes:
            # 认证中心
            - id: auth
              uri: http://localhost:7000
              predicates:
                - Path=/auth/**
              filters:
                - StripPrefix=1
            # 系统服务
            - id: system
              uri: http://localhost:8001
              predicates:
                - Path=/system/**
              filters:
                - StripPrefix=1
      redis:
        host: #YOUR-REDIS-ADDRESS
        database: 0

kind: ConfigMap
apiVersion: v1
metadata:
  name: auth-dev
  namespace: wm-test
data:
  application.yml: |-
    local:
      feign:
        server:
          system:
            url: http://localhost:8001
    spring:
      profiles: dev
      redis:
        host: #YOUR-REDIS-ADDRESS
        database: 0

kind: ConfigMap
apiVersion: v1
metadata:
  name: system-dev
  namespace: wm-test
data:
  application.yml: |-
    spring:
      profiles: dev
    springfox:
      documentation:
        swagger-ui:
          enabled: true

active spring profile to dev

paging

GET http://localhost:8001/dict/type/list?pageNum=1&pageSize=10&orderByColumn[]=dictName,dictType&orderDesc[]=true,false

orderByColumn and orderDesc need one-to-one correspondence
