1.1 数据库环境

l 本项目的重点在前端和后端，提供的数据库，没有分库分表。

1.2 后端环境

1.2.1 父工程：changgou4_parent_ali

l 修改pom.xml文件，确定spring boot、spring cloud、spring cloud Alibaba 等版本

  cloud:
    nacos:
      discovery:

    gateway:
      discovery:
        locator:
          enabled: true               #开启服务注册和发现的功能，自动创建router以服务名开头的请求路径转发到对应的服务
          lowerCaseServiceId: true    #将请求路径上的服务名配置为小写

l 拷贝跨域配置类 GlobalCorsConfig

package com.czxy.changgou4.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpMethod;
import org.springframework.http.HttpStatus;
import org.springframework.http.server.reactive.ServerHttpRequest;
import org.springframework.http.server.reactive.ServerHttpResponse;
import org.springframework.web.cors.reactive.CorsUtils;
import org.springframework.web.server.ServerWebExchange;
import org.springframework.web.server.WebFilter;
import org.springframework.web.server.WebFilterChain;
import reactor.core.publisher.Mono;

/
 * @author manor
  
 */
@Configuration
public class GlobalCorsConfig {

    @Bean
    public WebFilter corsFilter2() {
        return (ServerWebExchange ctx, WebFilterChain chain) -> {
            ServerHttpRequest request = ctx.getRequest();
            if (CorsUtils.isCorsRequest(request)) {
                HttpHeaders requestHeaders = request.getHeaders();
                ServerHttpResponse response = ctx.getResponse();
                HttpMethod requestMethod = requestHeaders.getAccessControlRequestMethod();
                HttpHeaders headers = response.getHeaders();
                headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_ORIGIN, requestHeaders.getOrigin());
                headers.addAll(HttpHeaders.ACCESS_CONTROL_ALLOW_HEADERS,
                        requestHeaders.getAccessControlRequestHeaders());
                if (requestMethod != null) {
                    headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_METHODS, requestMethod.name());
                }
                headers.add(HttpHeaders.ACCESS_CONTROL_ALLOW_CREDENTIALS, "true");
                headers.add(HttpHeaders.ACCESS_CONTROL_EXPOSE_HEADERS, "*");
                if (request.getMethod() == HttpMethod.OPTIONS) {
                    response.setStatusCode(HttpStatus.OK);
                    return Mono.empty();
                }
            }
            return chain.filter(ctx);
        };
    }

}

l 创建启动类

package com.czxy.changgou4;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

/
 * @author manor
  
 */
@SpringBootApplication
@EnableDiscoveryClient
public class CGGatewayApplication {
    public static void main(String[] args) {
        SpringApplication.run(CGGatewayApplication.class, args );
    }
}

1.3 前端环境

1.3.1 构建项目：changgou4-fore

l 步骤一：使用脚手架构建项目

npx create-nuxt-app changgou4-fore

l 步骤二：npm打包方式、axios第三方模块、SSR渲染模式

1.3.2 整合axios

l 步骤一：创建~/plugins/apiclient.js文件

l 步骤二：编写nuxt整合模板，用于统一管理ajax请求路径

const request = {
  test : ()=> {
    return axios.get('/test')
  }
}

var axios = null
export default ({ $axios, redirect }, inject) => {

  //赋值
  axios = $axios

  //4) 将自定义函数交于nuxt
  // 使用方式1：在vue中，this.$request.xxx()
  // 使用方式2：在nuxt的asyncData中，content.app.$request.xxx()
  inject('request', request)
}

l 步骤三：配置apiclient.js插件，修改nuxt.conf.js配置文件完成操作

 plugins: [
    { src: '~plugins/apiclient.js'}
  ],

l 步骤四：修改nuxt.conf.js配置文件，配置axios通用设置

axios: {

baseURL: ‘http://localhost:10010’

l 步骤五：测试 apiclient.js是否配置成功，访问test时，出现404

async mounted() {

let { data } = await this.$request.test()

console.info(data)

1.3.3 拷贝静态资源

l 将所有静态资源拷贝到static目录中

l 通过浏览器访问静态页面

http://localhost:3000/index.html

1.3.4 修改Nuxt项目默认项

l 1）修改默认布局，删除已有样式

l 2）删除pages目录下的所有内容

1.3.5 配置公共js和css

l 修改默认布局，添加公共js和css

<template>
  <div>
    <nuxt />
  </div>
</template>

<script>
export default {
  head: {
    title: '首页',
    link: [
      {rel:'stylesheet',href: '/style/base.css'},
      {rel:'stylesheet',href: '/style/global.css'},
      {rel:'stylesheet',href: '/style/header.css'},
      {rel:'stylesheet',href: '/style/footer.css'}
    ],
    script: [
      { type: 'text/javascript', src: '/js/jquery-1.8.3.min.js' }
    ]
  }
}
</script>

<style>

</style>
