How to check your version and upgrade JHipster

A quick tutorial on checking and updating your version of JHipster

The last few months of my life have been full of Angular + Spring Boot projects and I have been having a blast. When you start building these types of applications you need to start looking into JHipster. 

Greetings Java Hipster

If you’re new to JHipster I wrote up a tutorial titled “What is JHipster & Why you need to start using it today”. In this short post, we are going to look at how to tell what version of JHipster you’re running and how to tell if there are updates available. If there are updates available you will wanna upgrade to the current version. This is not a tutorial on upgrading a current application from one version to another as there is a little more work involved in that.

The first release of Spring Boot 2.0 is now available!

We have our first available release of what promises to be an awesome release

I have had a lot of fun watching the Spring Boot project grow into an amazing product over the last few years. A month ago I looked at the Spring 2.0 Roadmap and today we get to start walking down that road. 

Spring Boot 2.0

It is so exciting to see all of the new features coming in both Spring Framework 5 and Spring Boot 2.0. In this article, we are going to look at the first milestone release of Spring Boot 2.0. We will talk about how to update your current projects, start a new one and a brief look at the new features. 

Spring Beans @Component vs @Bean

What is the difference between @Component and @Bean.

I received a question from a student in my Spring Boot Introduction course that I would like to share with you. 

Dan uses @Service annotation for the NotificationService to add it to the application context yet the User class doesn’t need any annotation to be added to the class itself.  He just used the @Bean annotation in the SpringBeansApplication class for it to be added to the application context.  Why is that? 

Spring Beans

This is actually something that a lot of people are confused by. In this article, we will look at the difference between @Component (Spring Stereotype Annotations) and @Bean.

Getting Started with the Spring Boot Actuator

What is the Spring Boot Actuator and how can we use it in our applications?

Spring Boot includes a number of additional features to help you monitor and manage your application when it’s pushed to production. You can choose to manage and monitor your application using HTTP endpoints, with JMX or even by a remote shell (SSH or Telnet). Auditing, health and metrics gathering can be automatically applied to your application.

In this article, we will take a look at how to include the actuator in your next project and what endpoints are available.

When I hear people talk about taking online courses I hear the usual marketplaces mentioned. While these are great places to learn I find it a little odd that iTunes U is usually a place that people forget about.

In this article, I am going to give you 6 courses that can help you grow as a Software Developer. While some of the courses on iTunes U are a little out of date I believe these courses can be of help to you right now.

Moving from Tomcat to Jetty in your Spring Boot Application

Spring Boot does include some sensible defaults but it will not stand in your way.

I love getting questions from students because it gives me a great idea of the real world problems people are trying to solve. Today’s question comes from a student in my Spring Boot Introduction Course and has to do with using something other than the default. 

When I start a new Spring Boot Project and I include the web dependency I get Tomcat as the default servlet container. If I want to change that to something else like Jetty can I?

Moving from Tomcat to Jetty

The great thing about Spring Boot is that while it comes with some sensible defaults to get you up and running it doesn’t stand in your way if you need to change something. The answer to this question is Yes and in this short tutorial, we will look at how you can do this.

How to Make your weakness your strength

We need to identify our weaknesses and make them our strengths

I have been writing software for a fairly long time now. I have worked on applications that range from open source projects to a suite of applications that run a $5B dollar company. If you want to stay relevant in this industry though you have always got to be learning and improving your craft. One of the best things you can do is identify an area of weakness and work on improving it.

Computer Science Problem Sets

A friend of mine is preparing for an interview next week and asked for some help. I haven’t been on an actual coding interview in probably 10 years so I might not be the best person to ask but, what are friends for.

In this article, we are going to look at some exercises he was trying to tackle. These questions led me to realize that I have a weakness that I would like to improve on. 

How to start writing Angular & Spring Applications

A quick guide to getting started with Spring Boot & Angular 4

If your story reads anything like mine this is going to be an exciting post. I have worked with Angular JS 1.x in both projects and large scale projects at work. I honestly liked the framework but always felt that it was a bit too boilerplate and complex.

Do More with Angular & Spring Boot

Now that Angular 2, and subsequently Angular 4 has been released I have spent the last few months catching up. If you ever felt like I did towards Angular 1.x I am here to tell you that it is time to give Angular another look. 

I absolutely love building Angular 2 & Spring Applications and in this article, I am going to give you some resources to help kick start your journey.
