Use Apollo as Configuration Center

To use Apollo as configuration source in ServiceComb Java Chassis services:

  • Start Apollo service and create a project to associate with Chassis service, then generate a token

    How to use Apollo configuration center

  • Import config-apollo in pom:

    <dependency>
      <groupId>org.apache.servicecomb</groupId>
      <artifactId>config-apollo</artifactId>
 </dependency>

  • Configurations for Apollo itself in microservice.yaml, for example:

    apollo:
  config:
    serverUri: http://127.0.0.1:8070	#Apollo portal server address
    serviceName: apollo-test		#service name use AppId in apollo
    env: DEV				#default value DEV
    clusters: default		#default value default
    namespace: application		#default value application
    token: 				#get token from Apollo web pages

  • Start Chassis service and update configurations in Apollo portal service.

    Compile the source code, and use mvn exec to execute the main class MainServer.

    mvn clean install
cd config-apollo-sample/
mvn exec:java -Dexec.mainClass="MainServer"

  • Verify configurations can be configured dynamically.

    Before publishing a new configuration items from apollo portal, MainServer will just print DynamicProperty: {name=timeout, current value=default}

    After timeout configuration is published with value 100, MainServer will print DynamicProperty: {name=timeout, current value=100}
