Day425&426.购物车服务 -谷粒商城

• springboot初始化

• 新增本地域名cart.achangmall.com

• 修改对应pom配置，与此次服务间版本对应
  • 引入公共依赖
  • 修改springboot版本
  • 修改springcloud版本

• 将提供的静态资源导入nginx服务，做到动静分离

• 修改页面对应的资源地址，修改只选nginx的静态地址，如：

• 主启动类com.achang.achangmall.cart.AchangmallCartApplication

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

• 配置文件achangmall-cart/src/main/resources/application.yaml

spring:
  cloud:
    loadbalancer:
      ribbon:
        enabled: false
    nacos:
      discovery:
        server-addr: localhost:8848
  thymeleaf:
    cache: false
  redis:
    host: 192.168.109.101
    port: 6379
  application:
    name: achangmall-cart

server:
  port: 30000

• 网关配置路由映射achangmall-gateway/src/main/resources/application.yml

        - id: cart_route
          uri: lb://achangmall-cart
          predicates:
            - Host=cart.achangmall.com

• 启动服务测试，访问：http://cart.achangmall.com/
