Remote debugging SpringBoot application

We all know how to run SpringBoot application in debug mode from our favorite IDEs(Eclipse/IntellijIDEA etc) and debug the code. Recently I had to debug a SpringBoot application which is running on a remote server. There is already lot of information on the Internet on how to remote debug java applications, but some approaches didn’t work for me. So, here I would like to share my findings. If application is running on localhost Suppose you are running your application on localhost only and remote debug from your IDE.

What I Learned in Week-14, 2020

It’s been tough time for everyone due to the Corona virus situation. Staying at home for weeks and weeks is not easy, but it is very necessary thing to do so that we don’t spread the virus. However, if I look on the bright side I used to spend minimum 3 hours for office commute everyday. Now I am using that time for various other activities including learning some new things.

Imposing Code Structure Guidelines using ArchUnit

While building the software we all agree, as a team, to follow a set of guidelines which are typically considered as best practices. But during the development, developers might violate those guidelines unknowingly or ignorance. Typically we rely upon code reviews or code quality checking tools like SonarQube, PMD etc to check for such violations. But some of the guidelines could be opinionated decisions which might not be able to automate using SonarQube, PMD etc.

What I Learned in Week-11, 2020

I come across many blog posts from various sources like Twitter, StackOverflow etc and some of them are very helpful. Also, in day to day work I learn few new things, explore some new tools. Usually I keep track of this information using Browser Bookmarks and Pocket. I thought may be this information could be useful for others too. So, I am going to share it weekly on my blog.

Selecting The Technology Stack for JCart

Selecting the right technology stack is very crucial and plays an important role in project success. Many of the architects (unknowingly??!!) try to make complex designs by trying to use all kinds of latest and greatest stuff. On the other hand some architects try to be in their comfort zone by limiting their technology stack to the technologies with which they are comfortable. Both approaches are dangerous. One should understand the business needs and pick the technologies that are necessary for project.

Developing a simple e-commerce application from scratch to production using SpringBoot

We can find plenty of information on any technical topic, be it Java, .NET, Python or any frameworks like Spring, Hibernate, CDI, JSF etc. You can find hundreds of well written blogs on many of these topics. For example, you can find lot of tutorials on how to use SpringBoot or how to use various mappings in JPA/Hibernate or how to do form validations in JSF etc. Also, there are plenty of books published by well established publishers on most of the technologies.

Clean Code: Don’t mix different levels of abstractions

We spend more time on reading code than writing. So if the code is more readable then obviously it will increase the developer productivity. Many people associate readability of code with coding conventions like following standard naming conventions, closing file, DB resources etc etc. When it comes to code reviews most of the people focus on these trivial things only, like checking for naming convention violations, properly releasing resources in finally block or not.

Keep The Code Clean: WatchDog & SpotTheBug Approach

Before going to discuss WatchDog & SpotTheBug Approach, let me give a brief context on what is the needs for this. Three months back I was asked to write core infrastructure code for our new application which uses all the latest and greatest technologies. I have written the infrastructure code and implemented 2 usecases to demonstrate which logic should go into which layer and the code looks good(atleast to me :-)).

Are frameworks making developers dumb?

Last week I got to take interviews to hire senior java developers with around 5 years of experience. But after the interview process is over I felt like the frameworks makes developers life easier but at the same time making them dumb. Everyone puts almost all the new frameworks on their resume claiming they have “Strong, working experience on Spring, Hibernate, Web Services etc”. Here is how the interviews went on.
