Spring boot change context path and server port

If you want to change the application context path (application root) and server port for any spring boot application, you can utilize any of below two methods:

1. application.properties file

Use server.port and server.contextPath properties.

#server port
server.port=9000

#application root
server.contextPath=/springexamples

2. Customize WebServerFactoryCustomizer

Implement WebServerFactoryCustomizer interface and override customize() method.

import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;
import org.springframework.stereotype.Component;

@Component
public class CustomizationBean implements WebServerFactoryCustomizer<ConfigurableServletWebServerFactory> {

	@Override
	public void customize(ConfigurableServletWebServerFactory server) {
		server.setPort(9000);
		server.setContextPath("/springexamples");
	}

}
