run maven spring boot project command line with code examples

Running a Maven Spring Boot project from the command line can be done using the mvn command followed by the appropriate arguments.

First, ensure that you have Maven installed on your system by running the following command:

mvn -v

This should display the version of Maven that is currently installed on your system.

Next, navigate to the root directory of your Spring Boot project. This is the directory that contains the pom.xml file.

To run the project, use the following command:

mvn spring-boot:run

This will compile and run the project, and the application will be available at http://localhost:8080 by default.

You can also specify a different port for the application to run on by using the following command:

mvn spring-boot:run -Dspring-boot.run.arguments=--server.port=<port number>

Alternatively, You can package the project as a JAR or WAR file using the following command:

mvn clean package

This will create a JAR or WAR file in the target directory. You can then run the project using the following command:

java -jar target/<jar_file>.jar

In addition, you can also run the project by using the following command

mvn clean install

This will compile and package the project, and also run all the tests in the project.

Finally, you can also specify specific profile for the project to run with

mvn spring-boot:run -Dspring-boot.run.profiles=<profile_name>

In this way, you can easily run a Maven Spring Boot project from the command line using various options and parameters.

In addition to running a Maven Spring Boot project from the command line, there are several other related topics that are worth discussing.

One such topic is Spring Boot configuration. Spring Boot provides a number of ways to configure the application, including using application.properties or application.yml files, command-line arguments, and environment variables. These configuration options can be used to set properties such as the server port, database connection details, and other application-specific settings.

Another related topic is Spring Boot Actuator. Actuator is a set of tools that can be used to monitor and manage a Spring Boot application. It provides a number of endpoints that can be accessed over HTTP, such as metrics, health checks, and environment information. Actuator can be used to gain insight into the running application and troubleshoot any issues that may arise.

Another related topic is Spring Boot Security. Spring Boot provides a number of built-in options for securing a web application, including basic authentication and OAuth2. Spring Security can be used to secure the application by adding security configuration to the application and securing specific endpoints or resources.

Spring Boot also provides a number of options for deploying and running a Spring Boot application in different environments. Applications can be deployed to traditional on-premises servers, cloud platforms like AWS and GCP, or containerized environments like Docker or Kubernetes.

Finally, Spring Boot provides several options for testing a Spring Boot application. The Spring Boot Test module provides a number of annotations and utilities that can be used to write unit tests, integration tests, and end-to-end tests for a Spring Boot application.

In summary, running a Maven Spring Boot project from the command line is just one aspect of developing and deploying a Spring Boot application. There are many other related topics such as configuration, Actuator, security, deployment and testing that are crucial to building a robust, scalable and secure Spring Boot application.
