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.
I am new to spring boot and I am developing a simple spring boot API to store data to a couchbase db. Storing JSON objects have different formats.Is there any suitable method to achieve this?
Couchbase has given support for the JAVA SDK's that can help you easily integrate the couchbase api's and access the couchbase server to perform CRUD operation's here is the tutorial available : JAVA SDK
And also please take a look at this blog couchbase with Spring Boot sample example
How to random access chunks (start from any specific chunk, not necessarily from the first) in GridFS in Reactive MongoDB in the Spring Framework?
With the ReactiveGridFsTemplate available since Spring Boot 2.2 I cannot see any way.
Is there any low level method to do it?
NOTE: I opened a feature request in Spring Data Mongo Jira
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 have solr running at http://localhost:8983/solr/ . I have a Spring MVC app running at http://localhost:8080/login.jsp .
I would like to be able to Query only the solr data from my spring app. What is the best way to go about this? Does someone have a simple running example?
Integrate Solr with Spring using SolrJ.
SolrJ is the Solr Java Client Library which will allow you to query Solr and get back the results in java objects which you can use as Model objects with Spring MVC.
You can easily create a Repository which interacts with Solr using Solrj.
Also, secure the Solr Collections so that no one can access Solr from direct URL without authentication.
The Solrj Client with the Spring MVC app can query SOlr with Authentication.
You can also use spring-data-solr to do so. It should integrate quite nicely into an existing spring MVC application.
