Summarize the structure of Spring cloud:1, the request unifies through the API Gateway (Zuul) to access the internal service.2, the gateway received the request, from the registry (Eureka) to obtain available services3, after the balanced load by the ribbon, distributed to the backend specific examples4, micro-services through the feign communication processing b
Zuul as a business gateway needs to control its internal services, the use of OAUTH2 resources server integration into the Zuul can be very good protection of Zuul internal services, need to build a service registry, certification center, authentication Center, three major sections, The authentication center is integrated with

In the micro-service architecture, several basic service governance components are needed, including service registration and discovery, service consumption, load balancing, circuit breakers, intelligent routing, configuration management, etc., which are co-organized by these basic components to form a simple microservices system. A brief micro-service system such as:Note: A service and b services can be called each other, when the drawing is forgotten. And the configuration service is also regi
configuration, Spring Security provides a filter to intercept requests and authenticate users. If the user authentication fails, the page is redirected to /login?error , and the page displays the appropriate error message. If the user wants to log out of the login, the /login?logout page will display the corresponding success message by accessing the request and completing the logout.Here, we enable the ap
I. Background
Under the microservices architecture, our systems are split into multiple, single-duty microservices based on business.
Each service has its own set of APIs to provide to other service calls, so how to ensure security.
It is not that you want to invoke the call, we must have the authentication mechanism, is the request from our internal service, we can call our interface.

I. Background
Under the micro-service architecture, our system is broken down into a number of single service micro services based on business.
Each service has its own set of APIs to provide other service calls, so how to ensure security.
Not that you want to call can be invoked, must have a certification mechanism, is our internal services issued by the request before we can call our interface.
Need to pay attention to is that we are talking about
In previous versions of Edgware.release, the Zuul Gateway had a Zuulfallbackprovider interface with the following code:Public interface Zuulfallbackprovider {/** * The route this fallback would be a used for. * @return The route the fallback WI ll be used for. */public String Getroute ();/** * provides a fallback response. * @return the fallback response. */public clienthttpresponse fallbackresponse ();}where the Fallbackresponse () method allows the
