i want to create a setup in which i have template code(s) which when starting a new spring boot project can be easily added into the new project.
I tried finding stuff on net which mostly showed adding a custom service or a dependency in the project.
You can create a Spring Boot project that contains nested maven projects is called the multi-module project. this approach give you option to add or remove module (addon project or template)

For years, I've used Spring Initializr (at https://start.spring.io/) to create the initial SpringBoot application and then modify it to create the app. This works fine.
Is there a maven archetype I can use to create a SpringBoot app? Or is the Spring Initializr the only way to do this.
Searching I found this:
What archetype to choose for a simple java project
Which shows the command:
mvn archetype:generate -Dfilter=org.apache.maven.archetypes:
Which gives me a list of 14 items to choose from. None of them mention SpringBoot.
The closest match is org.apache.maven.archetypes:maven-archetype-webapp, so I tried it and it created a WebApp (*.war) which is not what I'm looking for.
The aim of the Maven archetype is for generating a project skeleton. The Spring Initialiser also does the same but I think you should find it more user friendly to use when compared to executing a maven archetype command.
If you insist to use maven archetype , you can simply search Github to see if there are people share their archetypes (search result at here)
If your aim is just to use command to generate a spring-boot project skeleton , Spring Initializr actually provide an HTTP API to do it.
Also you can checkout JHipster, which is another tool to generate a spring-boot project skeleton.
You could also use Spring Boot CLI to scaffold new Spring Boot projects:
spring init --dependencies=web,data-jpa my-new-project
It works just as Spring Initializr, but on the command line.
See section 2.4 "Initialize a New Project" on Spring Boot CLI documentation here: https://docs.spring.io/spring-boot/docs/current/reference/html/cli.html#cli.using-the-cli.initialize-new-project
I can initialize a spring boot project with initializr in idea, but what should i do if i want to add a new module. For example: I select web moduel first. And letter I want to add mybatis in the project.
You can add new module to your project in IntelliJ by
right-clicking your project -> New-> Module
You can follow this link
https://www.jetbrains.com/help/idea/creating-and-managing-modules.html#multimodule-projects
This will create a new module and also add your module to the settings.gradle file making it a multi module project
I have an existing project. I need to make it a Spring boot based project and I am using IntelliJ CE.
What would be correct procedure for doing it?
Edit:
Project has no initial structure. It is a totally empty project. So no existing modules etc.
Spring Boot is an Ultimate feature, so first you would need to try/buy the IntelliJ IDEA Ultimate.
From there, you can add Spring support to existing project modules or use the Spring Initializr wizard to select the necessary configuration when creating a new project or module.
In your maven pom.xml or build.gradle file, I would add the spring boot starter dependency:
spring-boot-starter (the group id is org.springframework.boot)
If the application is a web application, I would also add the web starter spring-boot-starter-web also with the same group id (org.springframework.boot)
For convenient features, applying the spring boot plugin would help in creating a runnable jar with all required dependencies bundled called a fat jar.
A great tool I use is the spring boot project generator. It allows you to configure the modules you want and create a project template.
Spring Boot requires IntelliJ IDEA Ultimate. If you want to use IntelliJ CE, please create a project using Spring Initilizer then import the same to your IntelliJ CE (File -> Open -> Choose the project root folder). After you import the project, wait for some time so that IntelliJ can download the dependency and build your project. You can check from (Build -> Build your project). Then find the main class of spring boot and run it using the green play button
I have previous experience in Spring MVC but I am new to Spring Boot.
I am Using IntelliJ for the first time.
What I noticed is that when you create a Spring boot project with security dependencies added during the time of creation, Then the IDE creates the project already configured With Basic Authentication whereas if I add dependencies to pom.xml after creation, then the application won't get configured with basic authentication automatically.
Can anyone explain this behavior of IntelliJ and can anyone help me with steps for configuring the pre-created project with Basic Authentication?
IntelliJ is using
https://start.spring.io/
to initialise your project. After the project is initialised, the IDE doesn't modify your code in any way. That is the normal behaviour and it is not Spring Boot related.
NOTE: The dependency that you add in your pom.xml is just pulling down that dependency, but if you need to use it you do the code yourself. (More information about Maven: https://en.wikipedia.org/wiki/Apache_Maven)
We need to be able to pull out domain classes (i.e. entities) from a Spring Roo project in order to reuse them for a Spring Batch project.
Is this possible?
Bearing in mind that we rely on Maven as our build and dependency management tool, and that our Roo project is already created, can we switch to a multi-module architecture?
If so how?
I don't think there is a roo command for converting a single module maven project to a multi module project.
One option would be to use roo to create a separate persistence module in your current project and manually migrate your entities and configuration over.
