问题 I created a Java application that can use SQL Server or Neo4j as a database without touching the application layer, I just modify the provider and the connection information, like follows: <?xml version="1.0" encoding="UTF-8"?> <persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd" version="2.0"> <persistence-unit

MongoDB to Java integration

由 北战南征 提交于 2019-11-30 13:24:04
We am trying to convert our old Oracle sql application into NO-SQL and we have chosen Mongo DB. Are there any ORM support for Mongo DB like Hibernate that reduces our coding? Can we use JPA specification to build an application for Mongo DB ? If JPA, which ORM Vendor is best to choose and why ? Have they come up with no-sql dialect for Mongo DB so that we can build an application using a non relational DB ? DataNucleus JPA provides full persistence to MongoDB using real JPA (as opposed to Spring-Data, Morphia etc which have their own APIs, hence you don't have direct portability - but that may

What's the difference between Spring Data MongoDB and Hibernate OGM for MongoDB?

I have not used Spring Data before but I've used Hibernate ORM a number of times for MySQL based application. I just don't understand which framework to choose between the two for a MongoDB based application. I've tried searching for the answer but I can't find the answer which does a comparison between the two in a production environment. Has anyone found problems working with these two frameworks with MongoDB ? Disclaimer: I am the lead of the Spring Data project, so I'll mostly cover the Spring Data side of things here: I think the core distinction between the two projects ist that the

Hibernate with MongoDB

问题 I'm looking for resources showing how to integrate MongoDB with Hibernate (preferably from within spring) so that I can switch between a RDBMS and a NoSql alternative: does anyone have experience doing this? 回答1: You can't easily do this. The point of Hibernate is to map Java Objects to a relational database. Although Hibernate abstracts a lot of details away you still need to understand how relational databases work with things such as foreign and primary keys, and the performance
