gateway 注册到nacos

先要排除web-starter这个依赖

 

 <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
            <version>2.2.5.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>
            <version>2.2.5.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bootstrap</artifactId>
            <version>3.0.4</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
            <version>2.2.5.RELEASE</version>
        </dependency>

application.yml 配置如下

spring:
  application:
    name: mall-gateway
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.1.137:8848
    gateway:
      routes:
        - id: route1
          uri: http://www.baidu.com
          predicates:
            - Query=url,baidu
        - id: route2
          uri: http://www.jd.com
          predicates:
            - Query=url,jd
server:
  port: 140

bootstrap.yml 配置如下

spring:
  application:
    name: mall-gateway
  cloud:
    nacos:
      config:
        server-addr: 192.168.1.137:8848

如果 你继承了父类模块中有mybatis等数据库链接的依赖  那么需要加上exclude来排除这些依赖 
但是也可以不继承父模块依赖  自己手动导入可以
package com.msb.mall.gateway;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@EnableDiscoveryClient
@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})/*因为comms服务中有mybatis依赖  需要将数据源配置手动排除*/
public class MallGatewayApplication {
    
    public static void main(String[] args) {
        SpringApplication.run(MallGatewayApplication.class, args);
    }
    
}
