there is an evident BUG in Query.java line 245 ( getReadPreference method)

[baggior]

spring-data-mongodb/spring-data-mongodb/src/main/java/org/springframework/data/mongodb/core/query/Query.java

Line 245 in 1ca64d9

return getMeta().getFlags().contains(CursorOption.SECONDARY_READS) ? ReadPreference.primaryPreferred() : null;

in method
public ReadPreference getReadPreference()

return getMeta().getFlags().contains(CursorOption.SECONDARY_READS) ? ReadPreference.primaryPreferred() : null;

I think should be

return getMeta().getFlags().contains(CursorOption.SECONDARY_READS) ? ReadPreference.secondaryPreferred() : null;

thank you for getting in touch - secondaryPreferred() forces reads to a secondary where as primaryPreferred() allows reads from secondary which is in line with what CursorOption.SECONDARY_READS says.
