Override Workspace property value

Spring Boot has many options to set or override the Workspace application properties. On startup, it loads properties from all places and saves them into objects—PropertySource. Then, the PropertySource objects are arranged in the order of priority.

When a Work.AI component tries to use any property value, Spring Boot starts searching this property from the first PropertySource by priority. For more details, refer to the official Spring Boot documentation.

Also, Work.AI uses the Spring Cloud Config ZooKeeper solution, and these properties are loaded into the system before all others.

Review loaded properties​

According to the information below and Workspace configuration, you can add the following properties:

  • Those set in ZooKeeper with a specific profile
  • Those set in ZooKeeper
  • Java System properties saved in the JAVA_OPS variable in the /bin/setenv.sh Tomcat file
  • OS environment variables
  • worksapce.properties file in the /conf Tomcat folder
  • application-{profile}.yml in war/jar
  • application.yml in the war/jar file
  • The default value set in the property object annotated by @ConfigurationProperties
  • bootstrap.yml

Pay attention to the following considerations:

  • In application.yml, you can set profile-specific properties:

    #application.yml properties
      spring:
        main:
          web-application-type: servlet
      ---
      # application-ws2.yml properties
      spring:
        profiles: ws2

  • The bootstrap.yml file has the least priority, but it is loaded at the Bootstrap phase where only Java System properties, OS environment variables, and bootstrap.yml are loaded.

Set properties in ZooKeeper​

You can set properties in ZooKeeper using the ZooNavigator UI.

  • URL: https://{instance-name}-wfaw-{aws-account}-ct1.workfusion.com:10999/zoonavigator

  • Connection string: {instance-name}-wfaw-{aws-account}-int1.workfusion.com:2181

To set ZooKeeper with a specific profile property, do as follows:

  1. Go to the /config/workspace,{your profile name} node, where {your profile name} is the name of your profile.
  2. Type in a new property and click the Create new node button.
  3. In the data window, set this property value.

In the example below, the property is app.value with the zookeeper-ws2 for the ws2 profile. This property value will be used if the ws2 profile is enabled.
