Is there any way to print Redis queries on console if we're doing any CRUD operation on Redis database from Spring Boot application like the way we do using jpa.show_sql ?
I did a web search but did find any yet.
I have created Bug here: https://jira.spring.io/browse/DATAREDIS-1014

I am looking to implementing User Session in Spring Boot application using Redis.
I have came across two great dependencies that aims to achieve these goals. Spring Data Redis and Spring Session Data Redis.
However, I have tried looking for differences of these dependencies, but to no avail.
From my understanding, if I am looking at only using Redis for Session Management, then I should use Spring Session Data Redis (even though Spring Data Redis works as well, but not as elegant).
On the other hand, if I am looking at using Redis for Session Management && Caching, then Spring Data Redis is a better option.
In general terms, Spring Session provides support for session management in Spring applications. It supports various different backends for storing session data, one of which is Redis. This Redis support is provided by Spring Session Data Redis.
Spring Session Data Redis builds on top of Spring Data Redis, using it to simplify its code that stores session data in Redis. Given this relationship between the two, this isn’t really a question of choosing one versus the other. Uses Spring Session Data Redis for session management while at the same time using Spring Data Redis to store you application’s own data is a common usage of the two projects.
Yes your understanding is correct. You can find the documentation for spring session data redis here and Spring Data redis here
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
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.
