#nacos的配置文件（DataID）默认的加载规则是： ${prefix}- ${spring.profiles.active}- ${file-extension}
#本次配置未使用spring.profiles.active

</dependency>启动文件修改【删除eureka配置】
删除@EnableEurekaClient即可
@SpringBootApplication(scanBasePackages = "com.chinaunicom.rxcx.gateway",exclude={ DataSourceAutoConfiguration.class , MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
@EnableDiscoveryClient
@EnableEurekaClient
@EnableFeignClients(basePackages="com.chinaunicom.rxcx")
@ComponentScan(basePackages="com.chinaunicom.rxcx")
public class GatewayServerApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayServerApplication.class, args);
System.out.println("网关启动成功-v9");
}
}替换为
@SpringBootApplication(scanBasePackages = "com.chinaunicom.rxcx.gateway",exclude={ DataSourceAutoConfiguration.class , MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
@EnableDiscoveryClient
@EnableFeignClients(basePackages="com.chinaunicom.rxcx")
@ComponentScan(basePackages="com.chinaunicom.rxcx")
public class GatewayServerApplication {
public static void main(String[] args) {
SpringApplication.run(GatewayServerApplication.class, args);
System.out.println("网关启动成功-v9");
}
}学习文档参考
https://nacos.io/zh-cn/docs/v2/quickstart/quick-start.html
开发环境，目前已改造gateway，其余服务通过同步工具同步至nacos，保障服务正常
错误
No Feign Client for loadBalancing defined.
spring-cloud-starter-alibaba-nacos-discovery依赖排除
