bootstrap.xml

server:
  port: 9100

spring:
  application:
    name: scgateway-demo
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
        namespace: b2b3c55a-abe5-47a4-a47e-03c57138d1d7
      config:
        file-extension: yml
        prefix: ${spring.application.name}
        server-addr: 127.0.0.1:8848
        namespace: b2b3c55a-abe5-47a4-a47e-03c57138d1d7
        group: DEFAULT_GROUP

启动类：

@EnableDiscoveryClient
@SpringBootApplication
public class SCGatewayApp {

    public static void main(String[] args) {
        SpringApplication.run(SCGatewayApp.class, args);
    }

}

nacos端配置：

 

spring:
  cloud:
    gateway:
      routes:
        - id: nacos
          uri: lb://nacos-payment-provider
          predicates:
            - Path=/payment-service/**
          filters:
            - StripPrefix=1
