We will cover here how to do DAO integration test when you have spring boot application with PostgreSQL DB and liquibase for schema versioning , last time we have explained how to do the same without liquibase using embedded PostgreSQL in this post but this time we will do the same but using docker with test containers which will apply your liquibase changes and making sure you DAO integration test has the same environment as production database environment if you are using docker for your data base in production .Continue reading
Here we will explain to use Junit 5 and Mockito 2 with Spring boot 2 when it comes to unit testing and integration tests .
Here we will go through how to use embedded PostgreSQL in you local development environment plus how to use it for DAO integration/unit testing if you have are using PostgreSQL as your production database , you DAO testing should use the same database as your production one to have behavior consistency and same environment precondition.
Now here we will share some possible designs when you use the spring boot event sourcing toolkit starter plus some remarks and action points .
What are some possible designs using the toolkit for event sourcing and CQRS services :
Here I am going to share a custom toolkit wrapped as a spring boot with AKKA persistence starter to act as a read made toolkit for event driven asynchronous non blocking flow API , event sourcing and CQRS implementation within spring boot services which can be part of spring cloud micro-services infrastructure .

Here we are going to cover how to use Ehcache 3 as a Spring caching in Spring boot based into JSR-107, before we start we need to just highlight what us JSR-107 :
In regards to caching, Spring offers support for two sets of annotations that can be used to implement caching. You have the original Spring annotations and the new JSR-107 annotations, for more information you can check :
When it comes to micro-services, it is really normal to have a configuration server that all your services will connect to fetch its own configuration but what about if you just need to externalize your configuration and make it manageable via source control like Git and your infrastructure is not yet ready for micro-services deployment and operation model.
What if you have spring boot app and you want to use spring cloud config semantic to do the same for you , is it possible to start embedded spring cloud config inside the your spring boot app to fetch its configuration remotely from Git for example ? the answer is yes and i am going to show how :
