I had an interesting problem come up at work last week and I would like to share it with you today. A coworker was having an issue with a Gradle build. Whenever he tried to compile the project it threw an error saying it couldn’t find the Groovy class he was trying to call from Java.
In this article, we are going to walk through setting up a project that will illustrate this problem. We will then examine what normal behavior is in a Gradle build and how we can make a change to fix this problem that we were facing.
After a few delays, Java 9 has finally been released. This is the first major release of Java since March 2014.
Java 9 is headlined by Jigsaw which is Java’s new modularity system. This is a huge change to how we will write Java programs going forward but there are also a lot of other great features being released in 9. In this article, we will talk briefly about some of the highlights in Java 9.
I am currently working on wrapping up a new section on MicroServices for my new course on JHipster. We could easily create a whole course around MicroServices alone so I am trying to keep this to more of an introduction.
I think one of the questions I hear most is “When should I use a MicroServices architecture in place of a Monolithic application?”. In this article, we will review what both of these are as well as give some recommendations on when to use Monolithic and when to use MicrosServices.
Angular CLI recently released its next major version, 1.3 (Hopper). There are some pretty great features in this release and I can’t wait to talk about a few of them here.
In this article, we are going to discuss how to check what version of the CLI you are running, how to upgrade and what new features 1.3 is giving us.
This question came in from a student in my Apache Groovy Development Course. It was actually quite interesting because it tripped me up at first before I understand what was going on behind the scenes.
The student was asking why when they created an integer but assigned to large of a number to it did the results end up like this.
int i = 2356524235623432414235234234
println i.class // java.lang.Integer
println i // 1413517242
I have been working really hard lately to wrap up my latest course on JHipster.
In one of the exercises, I have the students create their own application. In this application, one of the requirements is to make UI changes. When working with Angular you have probably come to expect to see those changes automatically reflected in the browser. In this tutorial, we will look at how to work with JHipster in Development.
In this tutorial, we are taking a look at a student’s question from my Spring Boot Introduction Course. This question has to do with the Spring CLI which is a great tool that allows you to quickly prototype with Spring.
I have created the spring boot application through spring CLI in the same way you showed in the video but my question is, How can we add multiple dependencies in our application through spring CLI? You have shown it for only one dependency i.e “web” using -d option but what if we want to add more dependencies through CLI?
In this article, I am going to talk through what the Spring CLI, how to install it and use it and of course answer the question above.
I think if I was given the choice to only keep a single website around I would have to go with YouTube. I love it for both entertainment and education and I love creating content on my channel.
I am going to share with you 3 YouTube channels I think you should subscribe to. The reason I chose these 3 is that they have all put out some really great content lately.
Last week I wrote an article on the improvements in Spring Boot 1.4 of startup errors. Specifically, we saw that we got a really informative error message when we try and run an application and port 8080 is already in use.
I received a question from a reader that went like this
“I get the port 8080 is already in use error from time to time and I am not sure how to fix it, what can I do?”
This is actually pretty easy to fix and happens to all of us. In this short article, I will show you how to do it on macOS and link to another article I wrote on how to do this on Windows.
In this tutorial, we are taking a look at a student’s question from my Spring Boot Introduction Course.
How can I use the @Query to specify an aggregation function in a select statement like…
“select post_date, sum(value) from post group by post_date”
retrieve it to a DTO and show on screen?
This is actually pretty easy to do using the @Query annotation. In this tutorial, I will show you how to do this using JQL and native SQL.
