when I debug query of criteria $in, i find a bug in the jar: [spring-data-mongodb-1.2.0.RELEASE-sources.jar
] file path: org.springframework.data.mongodb.core.query.Criter ia
the expect result is :{ "age" : { "$in" : [ 11 , 12 , 13]}}, but in fact the query is :{ "age" : { "$in" : [[ 11 , 12 , 13]]}}
my paramter is a list,
the result is :
2013-09-06 14:44:14,921-[HL] DEBUG main org.springframework.data.mongodb.core.MongoTemplat e - find using query: { "age" : { "$in" : [[ 11 , 12 , 13]]}} fields: null for class: class domain.model.Customer in collection: customer
but expected value is:
So I copy the "Criteria.java" in my project ,note the two mothod, add a new method,for example:
and it work!!!
