Third-party Methods of Generating ExternalId

Universe MDM provides the ability to implement third-party methods of generating External ID. The implemented methods become available for selection when configuring the entity/reference set and code attribute properties.

To use third-party generation methods:

1. Implement a Java interface that describes the algorithm for the third-party strategy. Example:

   public interface ExternalIdGenerator {
    /**
    * Generate external id by ctx
    * @param ctx ctx
    * @return return external id
    */
    Object generateExternalId(ExternalIdResettingContext ctx);
   }
   

2. Place the JAR file containing the implementation of the strategies in the <TOMCAT_HOME>/universe-integration directory.

3. Include third-party strategies in the universe-conf.xml file in the externalIdStrategies section. Configuration example:

   <conf:configuration xmlns:conf="http://conf.mdm.universe.com/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://conf.mdm.universe.com/">
         <conf:externalIdStrategies>
   <conf:strategy id="randomIdStrategy" name="Random ID Strategy" description="Generates random "long" value" class="com.unidata.mdm.backend.common.integration.strategy.RandomLongExt ernalIdGeneratorTest"/>
   ...
   
       </conf:externalIdStrategies>
     <conf:exits>
   

4. The id and name fields are mandatory. It is recommended to add a description of the strategy in the description.

5. Restart the system server.
