- Running a Spring batch at a schedule
Last time, I wrote a Spring batch application to index local markdown files into Apache Solr. While the default configuration of Spring batch is great, I don’t want to re-run the application to re-index all documents. In this tutorial I’ll show you how you can run a batch job at a certain schedule.
- Validating the input of your REST API with Spring
When handling input of a user, validation is a common task. In fact, it’s so common, that there’s even a specification for it called JSR 303 bean validation and JSR-380 which contains version 2 of the same specification. With Spring, we can utilize this specification to the fullest extent, and make validation an easier task.
- Indexing documents with Spring batch
Batch processing of information is a common thing to do when developing applications. Spring has its own framework to handle batch processing, called Spring batch. In this tutorial, I’ll use Spring batch to index markdown documents on my local disk onto Solr to make them easier to search for.
- Setting up Apache Solr with Tika using Docker
When indexing documents, Apache Solr is a possible solution. Combined with Apache Tika, you can also use Solr to index various types of documents, such as PDFs, Word documents, HTML files, … . In this tutorial, I’ll be setting up Solr with Tika using Docker compose.
- Writing GraphQL mutations with Spring boot
A few weeks ago, we created a beautiful API using GraphQL. We only had one problem… the application was completely read-only and no updates were allowed. This time, we’re about to change this, and implement our own mutations with GraphQL.
I've been blogging for quite a while!

- Rapid prototyping with Spring Boot and AngularJS
Recently I wrote an article about writing modern webapps with Spring Data REST and AngularJS. It’s not that hard to write, but it can be done even easier with Spring Boot as pointed out in the comments by Greg Turnquist. I already planned on trying out Spring Boot after some amazing articles about Spring Boot […]
- Using WebSockets with Spring, AngularJS and SockJS
A while ago I wrote a tutorial about writing a web application using Spring, AngularJS and WebSockets. However, that tutorial only used a fraction of what WebSockets could do, so in this tutorial I will explain how you can write a small chat app using the same frameworks; Spring, AngularJS, Stomp.js and SockJS.
- Writing real time applications using Spring and AngularJS (Part 3: AngularJS)
In the previous two tutorials I made the entire back-end for the real time application. You probably have noticed that the configuration part actually took longer than actually writing the application itself, this is because there’s a lot of magic behind the screens (think about the data access layer we didn’t have to write). This […]
- 2017: Year in review
While 2017 was mostly an inactive year for me, that doesn’t mean that we didn’t have any visitors! So let’s review what happened last year. Visitors The amount of visitors is similar to last year. While we gained a bit more visitors, we got less pageviews overall, but that makes sense, since we didn’t really […]

- CloudFlare, good or bad?
If you’re a developer like me and you spent some of your time on Reddit or StackOverflow, you probably might have encountered some articles about CloudFlare last week, like CloudFlare is ruining the internet (for me) and CloudFlare is ruining Stack Overflow for me with its recaptcha. Reading these articles made me want to evaluate […]
