I am using MongoDB with Spring, and Apache Shiro for session management. Since I encountered the same issue mentioned in this question, I resorted to using MongoTemplate directly instead of extending MongoRepository for implementing Realm class required by Shiro. This realm is simply a DAO that deals with MongoDB for user & role persistence.
At the moment, I have a strange issue with the Bean Definition XML. It throws an SAXParserException, and I cannot comprehend why.
I have provided some information below. Could you kindly help me with this?
