    Embedded Zuul Reverse Proxy

    -

    Spring Cloud has created an embedded Zuul proxy to ease the development of a very common use case where a UI application wants to proxy calls to one or more back end services. To enable it, annotate a Spring Boot main class with @EnableZuulProxy. This forwards local calls to /proxy/* to the appropriate service. The proxy uses Ribbon to locate an instance to forward to via Eureka. Forwarding to the service is protected by a Hystrix circuit breaker. Rules are configured via the Spring environment. The Config Server is an ideal place for the Zuul configuration. Configuration rules look like the following:

    Since zuul, by default, intercepts all requests (/*), to enable actuator, you should set the management.port.
