Hi Spring fans! In this installment (the first of 2018!) of Spring Tips we look at stream processing in Spring Boot applications with Apache Kafka, Apache Kafka Streams and the Spring Cloud Stream Kafka Streams binder.

Hi Spring fans! What a week! This week I'm in beautiful Dallas, TX, for the Spring One Tour Dallas event which is, like so many of the other cities already, utterly and completely sold out! What a crowd!

Since the first release of Spring Boot, it has been possible to bind properties to classes by using the @ConfigurationProperties annotation. It has also been possible to specify property names in different forms. For example, person.first-name, person.firstName and PERSON_FIRSTNAME can all be used interchangeably. We call this feature “relaxed binding”.

Unfortunately, in Spring Boot 1.x, “relaxed binding” turned out to be a little bit too relaxed. It was quite hard to define exactly what the binding rules were and when specific formats could be used. We also started to get reports of issues that were very hard to fix with our 1.x implementation. For example, in Spring Boot 1.x it is not possible to bind items to a java.util.Set…

What is it?

Micrometer is a dimensional-first metrics collection facade whose aim is to allow you to time, count, and gauge your code with a vendor neutral API. Through classpath and configuration, you may select one or several monitoring systems to export your metrics data to. Think of it like SLF4J, but for metrics!

Micrometer is the metrics collection facility included in Spring Boot 2’s Actuator. It has also been backported…
