How to deploy a multi-module project in Spring Boot?

You can deploy a multi-module Spring Boot project by following these steps:

1. Build the project using Maven or Gradle: Firstly, use a build tool like Maven or Gradle to assemble a multi-module project into an executable JAR file or WAR file. Make sure that the main module of the project (usually the main application or core module) includes an executable entry point.
2. Set up the deployment environment for the application: Choose an appropriate deployment environment based on your needs, such as local server, cloud server, or containerized environment (like Docker). Make sure your deployment environment meets the requirements of the project, such as Java version, memory configuration, etc.
3. To simplify the deployment process, you can create a deployment script to automate the deployment process. This script can be written using a scripting language (such as Shell script) or automation tool (such as Ansible).
4. Deploy the built executable file to the target environment: Place the built JAR or WAR file in the appropriate location of the target environment by using FTP, SCP, or other file transfer tools.
5. Start the application: In the target environment, initiate the application using the command line or deployment script. Make sure the application’s configuration files are properly loaded and that the application is running smoothly.
6. Monitoring and managing applications: Monitoring tools such as Prometheus and Grafana can be used to monitor the operational status of applications and perform necessary management operations like restarts or scaling as needed.

In summary, deploying a multi-module SpringBoot project requires building the project into an executable file, configuring the deployment environment, writing deployment scripts, deploying the files to the target environment, and starting the application.
