1、注册“gulimall-gateway”到Nacos

1）创建“gulimall-gateway”

SpringCloud gateway

2）添加“gulimall-common”依赖和“spring-cloud-starter-gateway”依赖

        <dependency>
            <groupId>com.bigdata.gulimall</groupId>
            <artifactId>gulimall-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-gateway</artifactId>
        </dependency>

　　

3）“com.bigdata.gulimall.gulimallgateway.GulimallGatewayApplication”类上加上“@EnableDiscoveryClient”注解

4）在Nacos中创建“gateway”命名空间，同时在该命名空间中创建“gulimall-gateway.yml”

5）创建“bootstrap.properties”文件，添加如下配置，指明配置中心地址和所属命名空间

spring.application.name=gulimall-gateway
spring.cloud.nacos.config.server-addr=192.168.137.14:8848
spring.cloud.nacos.config.namespace=1c82552e-1af0-4ced-9a48-26f19c2d315f

　　

6）创建“application.properties”文件，指定服务名和注册中心地址

spring.application.name=gulimall-gateway
spring.cloud.nacos.discovery.server-addr=192.168.137.14:8848
server.port=88

　　

7）启动“gulimall-gateway”

启动报错：

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class

　　

解决方法：在“com.bigdata.gulimall.gulimallgateway.GulimallGatewayApplication”中排除和数据源相关的配置

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})

　　

重新启动

访问：http://192.168.137.14:8848/nacos/#，查看到该服务已经注册到了Nacos中
