---------------------------------
Summary: SolrJ document object binding / BigDecimal
Key: SOLR-6539
URL: https://issues.apache.org/jira/browse/SOLR-6539
Project: Solr
Issue Type: Improvement
Components: SolrJ
Affects Versions: 4.10, 4.9, 4.10.1
Reporter: Bert Brecht
Fix For: 4.10.1
We are using BigDecimals in our application quite often for calculating. We
store our values typically as java primitives (int, long/double, float) and
using the DocumentObjectBinder (annotations based document object binding).
Unfortunately, we must have exactly the type given in solr schema for type used
as field/accessor. We found out, that the following patch would allow us to
define BigDecimal as type as we just use BigDecimal as a type in our mapped
POJO. This would help to make the mapping more powerful without loosing
anything.
