Testing your REST controllers and clients with Spring

That Spring allows you to easily develop REST APIs, is probably something we all know by now. With MockMvc and MockRestServiceServer, the same can be said to testing those REST APIs and clients. If you didn’t know this, then you’re at the right place to learn about it, as we’ll explore those options today!

Monitoring with Micrometer, Prometheus and Grafana

Monitoring is an essential aspect to the maintainability of applications, it’s no surprise that there are many platforms out there that allow you to properly monitor your applications. Usually, monitoring platforms work by using a time series database, which is a database optimised for time-based information, such as application metrics. Then on the other hand […]

Using WebSockets with Spring boot

A few years ago, I wrote an article about using WebSockets with Spring and AngularJS. However, the technologies have evolved over the years. That’s why I decided to write some up-to-date follow-up articles using the latest version of Spring boot and the latest version of the Angular framework. In this first follow-up article, I’m going […]

Generating documentation for your REST API with Spring REST Docs

Last time, we automatically generated documentation for our REST APIs written with Spring using Swagger annotations, Springfox and AsciiDoc. This allowed us to list all possible operations, models and so on. Additionally to such documentation, it could be interesting to have some examples as well. With Spring REST Docs we can automatically generate these examples […]

Generating documentation for your REST API with Spring and Swagger

A while ago, I used Springfox to include Swagger into our Spring projects. This allows us to use the Swagger UI tester to obtain some live documentation and testing for our REST APIs. However, sometimes you also want to have a static version of the documentation available, so that it can be printed, read without […]

Working with Spring Data Solr repositories

Spring Data is the go-to framework when trying to get access to a database within a Spring application. Next to relational databases it also provides support for a wide variety of noSQL databases, including document-based databases like Apache Solr. In this tutorial I’ll explore the various possibilities of using Spring Data Solr.

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.
