注意:
基于Spring Initializr方式创建商品服务模块zmall-product

在主模块pom.xml中加入商品服务子模块zmall-product

请求链路要求:客户端发送请求先经过nginx,再用nginx转至内部访问网关gateway,最后由网关服务的路由规则转发到微服务的内部服务。
在公共模块zmall-common中导入微服务相关依赖
com.alibaba.cloud spring-cloud-starter-alibaba-nacos-discovery
org.springframework.cloud spring-cloud-starter-openfeign
com.alibaba.cloud spring-cloud-starter-alibaba-nacos-config
配置商品服务模块zmall-product的application.yml文件
spring:application:name: zmall-productcloud:nacos:discovery:server-addr: localhost:8848
修改启动类,向nacos进行注册

这里请注意了,之前在商品服务模块zmall-product中已经配置了项目的静态资源,为什么还要在gateway网关服务中再配置一次呢?这是因为当请求经过gateway网关服务后会进行断言条件匹配和条件路径截取等操作,从而导致gateway网关路由转发后静态资源失效404的问题,所以特此在gateway网关服务中也配置一次项目网页素材中的公共静态资源js/css/images,确保能正常访问。
解决方案:(使用nginx动静分离方式实现)
配置静态资源访问服务器,将各个微服务模块中的静态访问资源迁移到静态资源访问服务器中,然后通过http方式访问即可。
