In micro services, a unified gateway is usually added to all services. The gateway mainly performs routing forwarding and transverse section functions (such as authentication, log collection, current limiting and counting).

Step 1: As a maven project, add the specified package in pom.xml

 <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> //Gateway also needs to be registered with the registry eureka
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId> spring-cloud-starter-netflix-zuul</artifactId>//This is the key jar package
        </dependency>
    </dependencies>

Step 2: The configuration file application.yml is configured as follows:

  spring:
      application:
        name: gateway
    ---
    server:
      port: 8080
      tomcat:
        uri-encoding: UTF-8
    spring:
      http:
        encoding:
          charset: UTF-8
          force: true
          enabled: true# Character set setting to solve the problem of Chinese to front ends becoming garbled
      servlet:
        multipart:
          max-file-size: 2048MB
          max-request-size: 200MB
    ribbon://Load Balancing Strategy
      ReadTimeout: 600000  # http build socket timeout time, milliseconds
      ConnectTimeout: 600000  # http read response socket timeout
    hystrix://Fuse
      command:
        default:
          execution:
            isolation:
              thread:
                timeoutInMilliseconds: 2400000
    zuul://Here is the service forwarding configuration
      routes:
          uaa:
            sensitiveHeaders:
            path: /uaa/**
            url: uaa
            stripPrefix: false
          activiti:
            sensitiveHeaders:
            path: /activiti/**
            serviceId: activiti
      add-proxy-headers: true
      add-host-header: true
      host:
        socket-timeout-millis: 300000
        connect-timeout-millis: 300000

Step 3: Configure the bootstrap.yml file

spring:
  profiles:
    active: test
---
#testing environment
spring:
  profiles: test
eureka:
  instance:
    prefer-ip-address: true
    lease-expiration-duration-in-seconds: 10
    lease-renewal-interval-in-seconds: 2
  client:
    service-url:
      defaultZone: http://---: 7002/eureka/ # Here is the registry address, just write IP.

Step 4: Configure the startup class Gateway Application. Now, if the environment is okay, it should be okay to run the main class directly.

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