In Spring Boot, to change the context path, update server.contextPath properties. The following examples update the context path from / to /mkyong or http://localhost:8080/mkyong

Note
By default, the context path is “/”.

P.S Tested with Spring Boot 1.4.2.RELEASE

1. Properties & Yaml

1.1 Update via a properties file.

/src/main/resources/application.properties

server.port=8080
server.contextPath=/mkyong

1.2 Update via a yaml file.

/src/main/resources/application.yml

server:
  port: 8080
  contextPath: /mkyong

2. EmbeddedServletContainerCustomizer

Update via code, this overrides properties and yaml settings.

CustomContainer.java

package com.mkyong;

import org.springframework.boot.context.embedded.ConfigurableEmbeddedServletContainer;
import org.springframework.boot.context.embedded.EmbeddedServletContainerCustomizer;
import org.springframework.stereotype.Component;

@Component
public class CustomContainer implements EmbeddedServletContainerCustomizer {

	@Override
	public void customize(ConfigurableEmbeddedServletContainer container) {

		container.setPort(8080);
		container.setContextPath("/mkyong");

	}

}

3. Command Line

Update the context path by passing the system properties directly.

Terminal

java -jar -Dserver.contextPath=/mkyong spring-boot-example-1.0.jar
