Most people do not understand the knowledge points of this article "how to use Zuul Gateway in Spring Cloud Microservice Architecture", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this article "how to use Zuul Gateway in Spring Cloud Microservice Architecture".

Brief introduction

Zuul is the micro-service API gateway in the Spring Cloud family bucket. All requests from the device or website will go through Zuul to the back-end Netflix application

Zuul mainly provides routing (request forwarding) and filtering

Zuul will eventually be injected into Eureka

Provide three major functions: proxy, filtering and routing

Use

Import dependency

Org.springframework.cloud spring-cloud-starter-zuul 1.4.6.RELEASE org.springframework.cloud spring-cloud-starter-netflix-eureka-client 2.0.2.RELEASE

Configuration file

Server: port: 9527spring: application: name: springcloud-zuuleureka: client: service-url: defaultZone: http://eureka1:7001/eureka/,http://eureka2:7002/eureka/,http://eureka3:7003/eureka/ instance: instance-id: zull9527.com # alias

Enable support

@ SpringBootApplication@EnableZuulProxy// enables zuul support and registers to Eurekapublic class Zuul9527Application {public static void main (String [] args) {SpringApplication.run (Zuul9527Application.class,args);}} by default

At this point, we can access it by address: Port number / service name / service.

Note: add 127.0.01 www,zuultest.com to the host file here

In order not to expose our service name, we can add to the configuration file

Zuul: routes: xxx.serviceId: provider-name # xxx represents any name xxx.path: / mydept/** ignored-services: provider-name # No longer access through this path, that is, direct access through the service name prefix: / lin # access path must be prefixed with / lin

This can only be accessed through the address: Port number / lin/mydept/ service

Add: why serviceId and path are used in configuration files and route is stored as key-value pairs in zull

Public void setRoutes (Map routes) {this.routes = routes;}

And in ZuulProperties,

/ * Represents a Zuul route. * / public static class ZuulRoute {/ * The path (pattern) for the route, e.g. / foo/**. * / private String path; / * * The service ID (if any) to map to this route. You can specify a physical URL or * a service, but not both. * / private String serviceId;} the above is about the article "how to use Zuul Gateway in Spring Cloud Micro Service Architecture".
