Class ReversedProxyHandlerMapping

java.lang.Object
org.springframework.context.support.ApplicationObjectSupport
org.springframework.web.reactive.handler.AbstractHandlerMapping
io.microsphere.spring.webflux.handler.ReversedProxyHandlerMapping
All Implemented Interfaces:
EventListener, org.springframework.beans.factory.Aware, org.springframework.beans.factory.BeanNameAware, org.springframework.context.ApplicationContextAware, org.springframework.context.ApplicationListener<io.microsphere.spring.web.event.WebEndpointMappingsReadyEvent>, org.springframework.core.Ordered, org.springframework.web.reactive.HandlerMapping
public class ReversedProxyHandlerMapping extends org.springframework.web.reactive.handler.AbstractHandlerMapping implements org.springframework.context.ApplicationListener<io.microsphere.spring.web.event.WebEndpointMappingsReadyEvent>
The performance optimization HandlerMapping to process the forwarded request from the reversed proxy web server, e.g, Spring Cloud Netflix Zuul, Spring Cloud Gateway or others. The request must have a header named "microsphere_wem_id", which is a string presenting the id of endpoint, used to locate the actual endpoint easily, such as HandlerMethod, HandlerFunction.

As a result, ReversedProxyHandlerMapping has the higher precedence than others, which ensures that it prioritizes getting the handler and avoid the duplication that was executed by the reversed proxy. As regards the details of endpoint, it's recommended to read the JavaDoc of WebEndpointMapping.getEndpoint().

For now, ReversedProxyHandlerMapping only supports to get the handlers from RequestMappingHandlerMapping.
