Avlesh Singh updated SOLR-1129:
-------------------------------
Attachment: SOLR-1129.patch
Adding a patch for this enhancement.
Existing test cases pass. I'll add new test cases in
{{TestDocumentObjectBinder}} shortly.
This is the approach I took.
# Dynamic fields can be annotated in the following manner
{code:java}
@Field("*_random")
public Map<String, Integer> random;
@Field("supplier_*")
public Map<String, String[]> suppliers;
@Field("oem_*")
public Map<String, List<String>> oem;
{code}
# Based on the {{value type}} of this {{Map}}, I populate all matching fields
in the response with their corresponding value(s).
# I added one more clause to the {{DocField}}'s {{storeType}} method to take
care of fields of type {{Map}}. Using {{getActualTypeArguments}} for this
{{ParameterizedType}} value, I populate the existing properties in the
{{DocField}} viz {{name, field, type, isArray, isList}} etc.
# I added a private method, {{getFieldValueByFieldName(SolrDocument sdoc,
String fieldName)}} in the {{DocField}} class, which is now being called by
the {{inject}} method for all fields. For regular index fields, the method
behavior has not changed. However, for a dynamic field (as annotated by the
client), this method prepares a {{Map}} of matching fieldNames and their
corresponding value(s). This in turn is used by the {{inject}} method to call
the client bean's corresponding setter method.
Please note that this fix is for version 1.3.
Cheers
