谷粒商城后台管理-前端概述

renren-fast注册nacos

引入gulimall-common依赖
renren-fast application.yml添加配置

application:
    name: renren-fast
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848

若配置不生效 则添加bootstrap.properties配置

启动后台项目事项

spring版本冲突
renren-fast版本 2.6.6
谷粒商城版本

<spring.boot.version>2.7.4</spring.boot.version>
<spring.cloud.version>2021.0.4</spring.cloud.version>
<spring.cloud.alibaba.version>2021.0.1.0</spring.cloud.alibaba.version>

API网关配置

gateway添加断言

将前端/api接口请求全部发送到renren-fast服务下

spring:
  cloud:
    gateway:
      routes:
      - id: admin_route
        uri: lb://renren-fast
        predicates:
        - Path=/api/**
        filters:
        - RewritePath=/api(?<segment>/?.*),/renren-fast/$\{segment}

503错误添加loadbalance依赖

<!--负载均衡-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-loadbalancer</artifactId>
        </dependency>

跨域问题

网关模块新增 注释renren-fast跨域配置CorsConfig

package com.atguigu.gulimall.gateway.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.reactive.CorsWebFilter;
import org.springframework.web.cors.reactive.UrlBasedCorsConfigurationSource;

@Configuration
public class GulimallCorsConfiguration {

    @Bean
    public CorsWebFilter corsWebFilter(){

        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.addAllowedHeader("*");
        configuration.addAllowedMethod("*");
        configuration.addAllowedOrigin("*");
        configuration.setAllowCredentials(true);
        source.registerCorsConfiguration("/**",configuration);
        return new CorsWebFilter(source);
    }
}
