Today we are going to talk about adding front end user interface to our application, from scratch. We can add the front end to our application using something called view resolvers. Our options are Apache Tiles, JavaServer Pages (JSP), etc. there are many other options, as well. Spring Boot supports FreeMarker templates, Groovy Templates and Themyleaf via “AutoConfiguration”, as the first class citizens. As the name suggests, we should not need to do a whole lot to get going with one of these. In this video we would be looking at Thymeleaf. I find it easy to use and feature rich at the same time. Thymeleaf is mostly HTML. Finally, we will talk about Web JARs & How to add Branding to our web application, using responsive web design.

In previous episodes (Part1, Part2) we saw how to create Java Maven project from scratch using SpringBoot – followed by how to deploy the application to docker and then I also demonstrated how can you set up MySQL database server, with automated initialization of a fresh database instance.
Now, let’s see how to set up RESTful Web API to display data from database using Hibernate ORM. We’ll also see how to set up a local development environment and docker deployment environment to quickly switch between the two, and establish an efficient work-flow for your project. Next, we’d set up our project to perform CRUD operations using Hibernate. And finally, we will create our Web API endpoints which can serve the requests made from the browser, in JSON format.
Previously, in this series we talked about getting started with docker and performing some elementary operations. In this episode, we’d dive deeper into docker, and then we’d swing by some of the commands you could use to follow along, and perform some common tasks in a terminal window.
Docker command line: Getting started
If you were to run a following command, you can see all containers, including the ones which are stopped, using the following command:
$ docker container ls -a
With following command, you can see all docker images:
$ docker image ls -a
As you can probably tell, this command is almost identical to the command to list (ls) all (-a).
Following are the equivalent commands to the two commands we saw above, respectively:
$ docker ps -a
$ docker images -a
Let’s say you want to, download (pull) a docker image, say MySQL, in advance. It is just like cloning a repository from GitHub:
$ docker pull mysql
If no tag is specified, then
:latest tag is assumed by default. Now to run this newly downloaded image, you can possibly run the following command:
Running the container:
$ docker run \ -d -e MYSQL_ROOT_PASSWORD=p4$$W0rd \ -e MYSQL_DATABASE=epidemics \ -e MYSQL_USER=epidemics \ -e MYSQL_PASSWORD=epidemics \ -p 3306:3306 \ --name mysql \ --mount type=bind,source=/abs_path/,target=/docker-entrypoint-initdb.d \ mysql
I created a video, for a web conference for my school. In this video I talk about how to perform initial groundwork to perform initial set-up. In the 2nd episode, I would talk more about the docker-compose v2, v 2.1 and v2.3.
