Ideas and field notes on engineering, design, and the architecture behind software that lasts. Written for people who care about how things are made.
In this post, I will describe how to host multiple SSL secured domains on a Linux server with only one external IP address. For a task like this, I usually prefer Nginx as a Reverse Proxy that is used to forward incoming requests to the corresponding backend applications.
This is a quick post that explains how to read a file from the resources folder (Classpath) within a Spring Boot command line application.
In one of my recent projects, I had the task to clean up existing Java classes regarding a typical cross-cutting concern problem. Access to certain methods within a web application should be logged, basically which user invoked which method using what kind of parameters. This is a situation when Spring AOP with custom annotations can provide a clean solution. In the following post, I will walk you through the entire process using a simplified solution.
In this post, I will walk you through the process of creating a minimal Spring Boot web application. I use a starter project like this quite often for checking out new features or creating a proof of concept (POC). The web application will have two separate areas, a publicly accessible site and a user/password secured admin site. This example shows how to create a custom form based login screen using bootstrap 3.
When I set up a new Linux server, I usually take couple of steps to secure the way I connect to the box using SSH. In this post I will walk you through the process to secure SSH access using firewall rules, changing the SSH port and enabling certificate based authentication. In this example I used a CentOS 7 box.
