Recently we’ve seen a rise in popularity of NoSQL databases. MongoDB has rapidly gained popularity in the enterprise and the Spring community. While developing and testing Spring Boot applications with MongoDB as the data store, it is common to use the lightweight Embedded MongoDB rather than running a full-fledged server. As the embedded MongoDB runs […]Continue reading

An exciting feature in Spring Framework 5 is the new Web Reactive framework for allows reactive web applications. Reactive programming is about developing systems that are fully reactive and non-blocking. Such systems are suitable for event-loop style processing that can scale with a small number of threads. Spring Framework 5 embraces Reactive Streams to enable […]Continue reading

In service layers, I’ve seen tests referred to as unit tests, but written with dependencies on the actual service, such as a database, web service, or some message server. Those are part of integration testing. Even if […]Continue reading

Transcript Okay, I’d like do a quick code review of my Spring Boot Mongo DB example application. This is up on github. And you can find it under my repository springframeworkguru/spring-boot-mongodb. (pretty creative name there) This is an example Spring Bood Application connect to Mongo DB. Not necessarily running in Docker. I connect can connect […]Continue reading

Out of the box, Spring Boot is very easy to use with the H2 Database. Spring programmers typically prefer writing code against such lightweight in-memory database, rather than on an enterprise database server such as Microsoft SQL Server or Oracle. In-memory databases come with several restrictions making them useful only in the development stages in […]Continue reading

When developing enterprise applications, Spring programmers typically prefer writing data-centric code against a lightweight in-memory database, such as H2 rather than running an enterprise database server such as Oracle, or MySQL. Out of the box, Spring Boot is very easy to use with the H2 Database. In-memory databases are useful in the early development stages […]Continue reading
