Zuul

what: micro gateway service, the equivalent of a reverse proxy server (this time with Nginx, Spring Cloud Gateway functionality is similar). Here record Spring Cloud integrated Zuul, Consul of use.

how it works：

The introduction of dependent (here registered service components with consul):

<dependency> 
    <the groupId> org.springframework.cloud </ the groupId> 
    <the artifactId> Starter-Spring-Cloud-Consul-Discovery </ the artifactId> 
</ dependency> 

<-! dependent as a self-contained spring boot starter web, actuator other dependent, dependent as it is a primer SpringBoot the project -> 
<dependency> 
    <the groupId> org.springframework.cloud </ the groupId> 
    <the artifactId> Starter-Spring-Cloud-Zuul </ the artifactId> 
    <Version> 1.4.7 .RELEASE </ Version> 
</ dependency>

Main categories:

@SpringBootApplication
@EnableZuulProxy
public class ZuulMain {
    public static void main(String[] args) {
        SpringApplication.run(ZuulMain.class, args);
    }
}

Configuration:

server:
  port: 8084

spring:
  application:
    name: sensestudy-zuul
          
  cloud:
    consul:
      enabled: true
      host: localhost
      port: 8500
      discovery:
#        serviceName: ${spring.application.name}
        tags: sensestudy, zuul
        healthCheckInterval: 15s
        fail-fast: false
        prefer-ip-address: true
#        health-check-path: ${server.servlet.context-path}/actuator/health



zuul:
#  prefix: /sensestudy # path unified prefix 
  ignored -services: '*' # default routing rules for the press service id to find the target address of the service, this configuration disables the default behavior, configure routing rules routes by the following 
  routes: 
    sensestudy - ACL: / ACL / ** 
    App1: 
      path: / coursecenter / ** 
      the serviceId: sensestudy-coursecenter

Description:

Default routing rules: for http: // localhost:? 8080 / sensestudy / myacl userId = 1, zuul it will try to initiate a request from a service registry to find the id myacl service. Disable the default rule is usually ignored-services by their own rules and specify the route.

Custom routing rules:

ACL-sensestudy: / ACL / ** : Zuul will match a request in which the specified path, and forwarded to the service id of the former. This is the most shorthand, as shown above, it can also be arranged in a plurality of rows with both the specified correspondence relationship.
