在启动类中，要排除数据源自动自动装配类，因为不使用数据库，所以不配置数据源

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

Bootstrap.yml文件

spring:
  application:
    name: gateway-service
  cloud:
    nacos:
      config:
        server-addr: 192.168.0.250:8848
        username: nacos
        password: nacos
        name: gateway-service.yml
        namespace: worker-dev_dev
        file-extension: yaml
        group: dev

因为配置了nacos，application.yml失效，所以下面的动态配置的yml内容在nacos中

server:
  port: 8000
  tomcat:
    uri-encoding: UTF-8
    max-swallow-size: 1024

spring:
