Spring Data MongoDB存储库查询串联如何工作？

Question

When I create a method of a Spring Data repository like findByName(…) everything works fine. But when using findByField1AndName(…) Spring Data MongoDB generates query only for the last parameter:

{ name : 'qwerty' }

But I expected it generates

{ field1 : 'something', name : 'querty' }

What's the problem? Please help.

UPD1: If anyone has such a problem, you can use @Query annotation to manually build your query, example below:

@Query("{ region: ?0, product: ?1, direction: ?2, deliveryCondition: ?3, sortament: ?4}")
QuotationKey findByRegionAndProductAndMarketDirectionAndDeliveryConditionAndSortament(
        Geography region, Product product, MarketDirection direction,
        DeliveryCondition deliveryCondition, Sortament sortament);

Answer 1

Not sure if am missing something. I tried 1.0.3 and 1.0.4 and it still doesn't work. The only working version right now looks like 1.0.1

When i tried for something like findByZipCodeAndName with 1.0.3 and 1.0.4, this is what i see in logs

MongoQueryCreator [DEBUG] Created query Query: { "zipCode" : "test"}, Fields: null, Sort: null

With 1.0.1 it works as expected:

MongoQueryCreator [DEBUG] Created query { "zipCode" : "test" , "name" : "blah"}

Apparently in the new releases only the first field is interpreted and queried for.

It seems you stumbled over a bug present in 1.0.2 and 1.1.M1. The fixes have been out for a while so upgrading to a recent version (1.0.4, 1.1 RC1) should do the trick.
