Spring Cloud Gateway registered to the server center (Consul)

Spring Cloud Gateway registered to the server center (Consul)

Preparing the environment

Start Consul (./ consul agent -dev) as a service center, the default is port 8500, and then start the spring-cloud-provider (9001 ports) and spring-cloud-provider-second ( 9002 ports) two projects as micro-services.
In the background you can see the two Consul management service starts:

Add a dependency Spring Cloud Gateway project

POM dependent increase in the following:

                <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-consul-discovery</artifactId>
        </dependency>

Modify Spring Cloud Gateway project configuration

server:
 port: 9000
spring:
  cloud:
    consul:
      host: 127.0.0.1
      port: 8500
      discovery:
        register: true
    gateway:
      routes:
        - id: test_route
          uri: lb://service-provider
          predicates:
            - Path=/service-provider/{segment}
          filters:
            - SetPath=/{segment}
  application:
    name: PC-ApiGateWay

• host: IP address of Consul
• port: Consul port number
• register: whether to register itself to the Consul
• lb: // service-provider: Consul service name to {lb: // access service name}
• Path: the routing path to match the format
• SetPath: Filter setting the path, is to match the access path can be set according to the delimiter
• name: to register themselves in the name of Consul

Start Spring Cloud Gateway Project

After starting Consul background you can see the registered content Spring Cloud Gateway project

Test Access

Access "127.0.0.1:9000/service-provider/hello?name=sws" this address, and refresh the page load balancing test gateway.

It can be seen backstage micro gateway proxy functionality services, and act as polling access.
