Creating a PROXY service in Spring Boot, that listens on multiple ports, and redirects the GET requests to a new URL

Question

Creating a PROXY service in Spring Boot, that listens on multiple ports, and redirects the GET requests to a new URL

Old URL from where requests will still be coming from - http://localhost:7010/DNTService?cptyXXX=89959623213123&portfolioXXX=03880774324234 To the new URL - http://wasp-uat-na.net/DNTService?cptyXXX=89959623213123&portfolioXXX=03880774324234

Is there a way in Spring that can help me achieve this???

So far using the steps in this "https://bitbucket.org/asimio/springboot-tomcat-multiple-ports/src/master/" I am able to listen on multiple ports but on adding the implementation for spring-cloud-gateway i get the below error:
