Hello everyone,
I was working with SolrJ and the v2 API and realized that some response
attributes were missing. The most notably is the collections attribute in
CollectionsApi.ListCollections response. This issue throws the error
UnrecognizedPropertyException during deserialization / parsing of the
response, if the api model has additional attributes.
After further investigation, I saw that there is an issue in the
api.mustache template file, in the constructor of line 73:
public static class {{operationIdCamelCase}}Response extends
JacksonParsingResponse<{{returnType}}> {
public {{operationIdCamelCase}}Response() {
super({{returnType}}.class);
}
}
The issue occurs for cases where the {{operationIdCamelCase}}Response
resolves to the same name as {{returnType}}. In the case of the example
above,
- {{operationIdCamelCase}}Response resolves to ListCollectionsResponse
- {{returnType}} resolves to ListCollectionsResponse
However, both point to
org.apache.solr.client.solrj.request.ListCollectionsResponse.
{{returnType}} should however point to
org.apache.solr.client.api.model.ListCollectionsResponse. This leads to
missing attributes defined in the API model.
This bug affects probably about 35 responses. This can be checked by
looking up all imports in org.apache.solr.client.solrj.request that match
the following regex:
import org.apache.solr.client.api.model.[A-Z-a-z]+Response;
The easiest fix would probably be to use fully qualified names in
returnType. Should I open an issue on Jira or has this already been
addressed elsewhere?
Best Regards,
Christos
