it only working with spring-boot-starter-web::2.0.0.RELEASE

I have tried

server.servlet.context-path=/test

But nothing happened to me still serve on url http://localhost:8080/

Answer 1

If you use the servlet API then the property is now called

server.servlet.context-path=/myapp

Answer 2

As confirmed by Andy Wilkinson @andy-wilkinson of the Spring Boot team via Gitter

There’s no concept of context path in WebFlux so there’s no equivalent property

i.e WebFlux doesn't support context path configuration

Answer 3

In reference to Spring Boot 2.x. below configuration apply for application.yml

server:
  port: 8080
  servlet:
    context-path: /test

For application.properties configuration are

server.port=8080
server.servlet.context-path= /test

Answer 4

For use cases where WebFlux application is behind load balancer/proxy you can use dedicated class - ForwardedHeaderTransformer that will extract path context from X-Forwarded-Prefix and will add it to ServerHttpRequest.

Doing so you won't need to modify global context-path (which does not make sense in WebFlux)
