How to configure the tomcat port in springboot

In Spring Boot projects, the port of the Tomcat server is usually through a configuration file (or) to set it. Here are some common configuration methods:

use

existsrc/main/resources/In the file, you can set the port of Tomcat through the following properties:

=8080

use

If you prefer to use YAML configuration files, you cansrc/main/resources/Set this in the file:

server:
port: 8080

Setting through environment variables

You can also change the port by setting environment variables, which is very useful in containerized applications such as Docker. For example, on Linux or Mac, you can set environment variables before starting the Spring Boot app:

export SERVER_PORT=8080

On Windows, you can use:

set SERVER_PORT=8080

Then launch your Spring Boot app.

Setting through command line parameters

You can also set the port through command line parameters when starting the Spring Boot application:

java -jar  --=8080

Or if you use Maven or Gradle plugin to run the application, you can set it up like this

./mvnw spring-boot:run -=--=8080

Or for Gradle:

./gradlew bootRun --args='--=8080'

Set it programmatically (not recommended)

While this is not recommended, as configuration files or environment variables provide better flexibility and maintainability, if you do need to set the port in your code, you can do it by implementing itWebServerFactoryCustomizerInterface to implement:

import ;
import ;
import ;
@Component
public class TomcatPortCustomizer implements WebServerFactoryCustomizer<TomcatServletWebServerFactory> {
@Override
public void customize(TomcatServletWebServerFactory factory) {
(8080);
}
}

Choose the best method for your needs to set up the port of Tomcat. Generally, using configuration files or environment variables is the easiest and most straightforward way.
