Mongo db with spring data document
3 likes1,902 views
This document discusses using MongoDB with Spring Data. It shows how to configure MongoDB drivers and templates as beans in Spring. It also demonstrates how to perform CRUD operations on MongoDB documents using Spring Data's MongoRepository interface, including implicit conversion between Java objects and MongoDB documents. Key features of MongoRepository discussed include query methods, custom queries, and asynchronous support.
