alibaba-nacos-discovery 延迟注册到nac

1、配置文件修改（关闭自动注册）

spring:

    cloud:

        nacos:

            discovery:

                registerEnabled: false

2、加载配置类（手动注册）

（注意该类，放在spring可以扫描到的包下）

import com.alibaba.cloud.nacos.registry.NacosServiceRegistry;

import lombok.extern.slf4j.Slf4j;

import org.springframework.beans.BeansException;

import org.springframework.boot.CommandLineRunner;

import org.springframework.cloud.client.serviceregistry.Registration;

import org.springframework.context.ApplicationContext;

import org.springframework.context.ApplicationContextAware;

import org.springframework.stereotype.Component;

/**

        Registration registration =applicationContext.getBean(Registration.class);

        nacosServiceRegistry.register(registration);

        log.info("项目加载nacos完成");

    }
