I am facing issues while creating a Multitenant application using spring boot and Redis. I have used the same solution which is mentioned in How to implement multitenancy for Redis in spring boot. But it didn't work. Is there a different way to implement Redis multitenancy with Spring boot.
I found the solution by adding a check if the data source not available in the cache then pull from the required source and create a connection. Also changed calling afterPropertiesSet() explicitly which is mentioned in How to implement multitenancy for redis in spring boot

I have read the Spring Boot documentation and I got knowledge about Spring Session from this document.
But I see that HttpSession class works without adding any dependencies in my code.
JDBC
Redis
Hazelcast
MongoDB
So...
I'm guessing that Spring Boot provides Session Storage by default. Does anyone know about this? I looked at spring docs but couldn't find it.
How to you run your app? Do you use Tomcat or Jetty embedded server or deploy it in those servers? They all have their own session storage implementation. Tomcat uses file-bases session storage by default.
The session storage that you mentioned by default is provided by the Servlet container.It is just an internal java.util.Map.
Spring Session is a Spring sub-project. It is optional and its purpose is to allow you swap the session stroage mechanism provided by the container with the one provided by Spring Session which can be RDBMS, Redis ,Hazelcast Cluster or MongoDB .HttpSession is then stored in the container agnostic way such that you can have session persistence /session clustering more easier. You no longer need to consult the Servlet container documentation for how to configure a cluster etc.
If you want to use Spring session, you still have to include the dependencies from the spring session project.
I was learning Microservice architecture from Spring Microservices In Action book.
As one of things I wanted to migrate examples which were built on Spring Boot 1.4.4 and Spring Cloud Camden.SR5 to Spring Boot 2.1.6 and Spring Cloud Greenwich.SR1.
Now, I'm having problems with migrating of OAuth2 Auth server and resource servers since Spring decided to change packages/placement of classes and I feel completly lost since nothing seems to work.
Documentation seems to be splitted into SpringBoot/SpringSecurity/SpringOAuth2 depedencies.
What is the proper way of implementing OAuth2 AuthServer and ResourceServer in current (2.1.6) version of SpringBoot with Spring cloud Greenwich?
I have a Spring Boot application that uses Spring Batch. I want now to implement an admin panel to see all job statuses. For this, Spring has "spring-batch-admin" But I see that is deprecated long time ago:
The functionality of Spring Batch Admin has been mostly duplicated
and
expanded upon via Spring Cloud Data Flow and we encourage all users to
migrate to that going forward.
But then Spring Cloud Data Flow says:
Pipelines consist of Spring Boot apps, built using the Spring Cloud
Stream or Spring Cloud Task microservice frameworks
So in order to use this functionality do I really need to convert my spring boot app to a microservice? Isn't this an overkill just to see some batch statuses? Also I can not install docker on my production server(for various reasons) Can I still use Spring Cloud Data Flow without docker?
Yes, spring boot batch should be wrapped as spring cloud task, which should not be too complicated.
If Docker does not suit your needs - https://docs.spring.io/spring-cloud-dataflow/docs/current/reference/htmlsingle/#getting-started-local-deploying-spring-cloud-dataflow
I want to have read and write datasources for replication purposes in spring boot app. Are there any examples on how to implement this behavior?
This could help you
Spring Boot Configure and Use Two DataSources
also you could take a look on this blog
This is what I was looking for http://fedulov.website/2015/10/14/dynamic-datasource-routing-with-spring/
I'm trying to find an out-of-the-box health check for my spring app. However, I can only find support for Spring Actuator. I'm not able to use Spring Actuator because my application is a Spring application and not a Spring boot app. Is there another library that I could make use of without having to write my own? I would ideally want an endpoint that could possibly give me data about whether my DB is up and possibly some of the java opts passed into that particular node
