In this post we will continue exploring the capabilities of Spring WebFlux by means of creating a basic CRUD application. We will not be using a database in this post because I did not want to be distracted with database stuff at this moment 😉 Adding a database will be handled in part 2. Furthermore, we will implement a few CRUD operations and see how we can unit test a Flux. Source code can be found at GitHub.
This post will be about how I got started with Spring WebFlux. A few weeks ago, I started to read in detail about Spring WebFlux, Reactive Streams, etc. Looking back at my journey, I did things in the wrong order. In this post I have tried to structure the information, in order to give you a plan for getting started with Spring WebFlux. The examples can be found on GitHub.

Did you ever had the problem that you did not know which version of your application was deployed on e.g. a test environment? Or you had to manually adapt version information for each release in order to make it available in an About-dialog? Then the Maven git commit id plugin comes to the rescue! In this post, we will build a Spring Boot application with a RESTful webservice for retrieving versioning information. The only thing we will have to do, is to configure the Maven git commit id plugin and create the webservice. After this, versioning information is automatically updated during each build!
In this last post about Java 9 modules we will take a closer look at some of the modules directives. We will explain what they mean and show the usage by means of an example. We will build upon the example used in part 1 and part 2, it is advised to read these posts before continue reading. The sources used in this post are available on GitHub in branch feature/modules-directives.
In this post we will take a closer look at Java 9 Modules. The focus lies on how modules affect us when using an IDE like IntelliJ and using a build tool like Maven. It is advised to read the post Java 9 Modules introduction (part 1). We will use the same example, starting with a single module application and afterwards converting it into a multi-module application. The examples used, can be found on GitHub.
In this post we will introduce the Java Platform Module System (JPMS) which is the biggest change in the Java 9 release. In this post we will take a look at some basics of JPMS (Why do we need modules? What has changed to the JDK?). After that, we will take a look at how a single module application can be created, compiled and executed. At the end, we will take a look at how a multi module application can be created, compiled and executed. In this post we will only use command line tools. The examples used, can be found on GitHub.
This week we will take a look at lambda expressions. We will take a look at some basics, show some of the standard functional interfaces, show how lambdas can be used with Streams and at the end it is shown how method references can be used. After reading this, you will have some basic knowledge of lambda expressions. The examples can be found at GitHub in the repository https://github.com/mydeveloperplanet/mylambdaplanet
