'The matching wildcard is strict, but no declaration can be found' Error connecting mongodb to spring - mongodb

Question

I'm trying to connect Spring to Mongodb. But it doesn't work somehow. In general, I've used Spring core 5.0.1, Spring data 2.0.1 ang Mongdodb driver 3.5.0. I also used the tag mongo:mongo-client host="localhost" port="27017" in creating an MongoDb Template bean. The dependencies were fully downloaded but probems still happened.
Please help. Here is the files:

The problem may refer to the line 'mongo:mongo-client...' in SpringConfig.xml, but I haven't found any way to fix that - since 2 days ago. Thank you very much.

You can try to replace the schema declaration
http://www.springframework.org/schema/data/mongo/spring-mongo-1.0.xsd
with
http://www.springframework.org/schema/data/mongo/spring-mongo.xsd
