REST interfaces in Reverse Proxy?

Question

Java

You need to implement the gray element in the figure with REST(IN/OUT) interfaces. The input interface accepts a task from the sender and, depending on its type, passes it to the appropriate addressee (system 1-3). After the recipient has processed the task, its response is returned to the sender. Since there are no external systems, they should be “docked” using any tool (wiremock, json-server). The configuration of addresses of external systems should be placed in the application.properties file in the form, for example, destination.get = localhost: 8899.

I can not figure out how to implement all this correctly in 1 project on localhost. I created a project with https://start.spring.io/ (c web dependency). Thanks in advance for your reply.

What are the problems? Install nginx and proxy.
