i managed to connect my spring boot application with postgres without hibernate, but with r2dbc for a reactive application.
I was wondering if i can connect spring boot to oracle database without hibernate for a non reactive application ?
Spring Data provides two basic modules for integrating applications with relational databases. Spring Data JDBC is for imperative applications while Spring Data R2DBC is for reactive ones. They both use the same interfaces and patterns. If you're familiar with Spring Data R2DBC, it will be straightforward to work with Spring Data JDBC.

I've migrated an entire project to reactive WebFlux, the only missing thing is the DB queries. At the moment I'm using JdbcTemplate and Hikari Datasources and I need to make DB calls reactive?
I tried to use vertx-db2-client but it seems it does not work fine with Webflux (or I'm not capable to use it correctly).
What options do I have? Can you show any working example with Webflux and DB2?
Thanks
You would need to find that the database DB2 is supported by Spring data reactive libraries. When I look at https://spring.io/projects/spring-data-r2dbc I don't see DB2 being in the list of database they support.
I was trying to create a CRUD app using spring boot and postgres ,alongwith spring native.But I couldn't find any proper documentation related to it apart from spring native documentation.
The part of how to integrate it with postgres,is what I am looking for.Thankyou
You can use Spring Data like you would in a standard Spring Boot application. Depending on the type of application, you can use Spring Data JDBC, Spring Data JPA (if you need the Hibernate features), or Spring Data R2DBC (for reactive apps). If you bootstrap your application from start.spring.io, you can directly select the PostgreSQL dependency from there.
To get started with Spring Data, you can refer to this guide on the Spring website: relational data access with Spring Data JDBC. It uses H2, but you can replace it with PostgreSQL. More details are available on the project documentation.
On my GitHub, you can find an example of Spring Boot application with a REST API, security, and data persistence with PostgreSQL. And packaged as a native executable through Spring Native. If you're new to Spring Native, I wrote an article about how to get started with it.
We want to try GraphQL in our Spring based application. (its not based on spring boot). Our data repository is MongoDB. I saw various examples based on node, which makes use of graphQL + Mongo. There is also library which is with spring boot!
Can it be used directly? Or there is non spring-boot lib available?
The main thing you'd gain from Spring Boot is auto configuration for Spring Data's Mongo driver.
If you're comfortable injecting the MongoRepository into the GraphQL data sources and resolves on your own, then no, you don't need Spring Boot
I need to connect a Oracle 12c DB and query a table and fetch the results.I am using Spring Boot 1.2.4.Now if I use Spring Data Jpa will it suffice this requirement or Do I need to use JPA provider like Hibernate or Open JPA is a must along with Spring Data JPA.
Is there any examples which use only Spring Data JPA without any third party JPA provider?
I am writing a rest service using Jersey. The data access layer will be developed using Spring JPA. I will be interested to know how can I pass database properties to the Repository layer.
