Spring Boot application change port

There are two ways to change the port of a Spring Boot application:

1. Using the server.port property: This is the most common way to change the port of a Spring Boot application. You can set the server.port property in the application.properties or application.yml file. For example, to set the port to 9000, you would add the following line to your configuration file:

server.port=9000

2. Using the --server.port command-line argument: You can also change the port of a Spring Boot application using the --server.port command-line argument. For example, to start the application on port 9000, you would use the following command:

java -jar my-application.jar --server.port=9000

Which method you use to change the port of your Spring Boot application depends on your preference. If you are deploying your application to a production environment, it is generally recommended to set the server.port property in your configuration file. This will make it easier to manage the port of your application.

Note: If you are using Spring Boot Actuator, you will also need to change the port of the actuator endpoints. You can do this by setting the management.port property in your configuration file.

Here is an example of a Spring Boot configuration file that sets the port to 9000 and the actuator port to 9001:

server.port=9000
management.port=9001

Once you have changed the port of your Spring Boot application, you can start the application as usual.
