Auto-generate unique key when adding documents from SolrJ
Hello all,
First of all, I am very new to Solr.
I am using Solr version 6.4.1. I have a Solr core (non-cloud), where there
is a mandatory unique key field called "id".
I am trying to add documents to the core from Java, without having to
specify the "id" field explicitly; i.e. to have it auto-generated.
I learned that this is possible by including the following information in
the conf/solrconfig.xml file:
> <updateRequestProcessorChain name="add-unknown-fields-to-the-schema">
> <!-- UUIDUpdateProcessorFactory will generate an id if none is present
> in the incoming document -->
> <processor class="solr.UUIDUpdateProcessorFactory">
> <str name="fieldName">id</str>
> </processor>
> ...
> <processor class="solr.LogUpdateProcessorFactory"/>
> <processor class="solr.DistributedUpdateProcessorFactory"/>
> <processor class="solr.RunUpdateProcessorFactory"/>
> </updateRequestProcessorChain>
(I did restart the server after adding the above text to the xml file.)
However, when I try to add documents from Java using SolrJ (without
specifying the "id" field), I get the following exception:
> Exception in thread "main"
> org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error
> from server at http://localhost:8983/solr/sales_history: Document is
> missing mandatory uniqueKey field: id
My Java code is like this:
> SolrClient solr = new HttpSolrClient.Builder(SOLR_URL).build();
> SolrInputDocument document = new SolrInputDocument();
> document.addField(..., ...);
> document.addField(..., ...);
> UpdateResponse updateResponse = solr.add(document);
The exception is thrown from the last line above.
Is there any way to add documents from Java and have the uniqueKey field be
auto-generated?
Thank you

It is not enough to declare URP chain, you have to invoke it.
Either by marking it default or by adding the update.chain parameter
to the request handler (or in initParams) you use to update the
documents (usually /update). See, for example:
https://github.com/apache/lucene-solr/blob/master/solr/server/solr/configsets/data_driven_schema_configs/conf/solrconfig.xml#L837
