Spring Data MongoDB - Where to create an index programmatically for a Mongo collection?
If you need to do it in programmatic way, you can just create new Spring's @Configuration and perform such initialization:
@Configuration@DependsOn("mongoTemplate")public class CollectionsConfig { @Autowired private MongoTemplate mongoTemplate; @PostConstruct public void initIndexes() { mongoTemplate.indexOps("collectionName") // collection name string or .class .ensureIndex( new Index().on("name", Sort.Direction.ASC) ); }}
