This article takes a more in depth view to the @SpringBootApplication annotation and its implemenation and implications.

Spring Fu is an experimental Kotlin micro-framework that makes it easy to create lightweight Spring-powered applications with functional APIs instead of annotations

Vendor-neutral application metrics facade

How Spring 5 leverages Java 8’s functional syntax and a new, reactive programming model.

As part of micro services development many of us are using Spring Boot along with Spring Cloud features. In micro services world we will have many Spring Boot applications which will be running on same/different hosts.

A demo for using jasper within a Spring Boot App I made for a Jasper session.

Mostly uses concept of JasperReportsViewResolver as defined here http://stackoverflow.com/questions/27532446/how-to-use-jasperreports-with-spring-mvc [Check the answer with the tick there :)]

Also the report included using my custom db and data so try putting your own .jrxml report there before trying to run.

The jasper endpoints shall be like http://localhost:8080/report/{reportname}?format={format}&id={id} (id param are optional,you can add ur custom report params there)

Cheers!

Java Rich Client Framework

Let's familiarize ourselves with the Spring RCP. New life seems to have been blowing into this project: after almost two years of hiatus, the 1.0.0 release came out a few months ago. Let's leave aside the question about its direction and so on and, instead, let's look purely at the technology itself to see exactly what it offers.

Either approaches mean you get smart completion of routing rules in your IDE whether in your Java or XML editor.
