【尚上优选】SpringBoot微服务项目

p1-p5.项目介绍以及基本的配置：

项目流程：

从具体模式看，主要围绕平台、团长、用户三个角色展开：

1. 团长创建一个群，提前发布优惠商品的链接供用户购买，团长从中抽取佣金
2. 用户提前一天下单
3. 平台在收集好订单之后，调动供应链，从仓库发货到自提点
4. 用户前往自提点提货
   

核心技术：

SpringBoot：简化新Spring应用的初始搭建以及开发过程

SpringCloud：基于Spring Boot实现的云原生应用开发工具，SpringCloud使用的技术：（Spring Cloud Gateway、Spring Cloud OpenFeign、Spring Cloud Alibaba Nacos等）

MyBatis-Plus：持久层框架

Redis：缓存数据库

Redisson：基于redis的Java驻内存数据网格，实现分布式锁

RabbitMQ：消息中间件

ElasticSearch +Kibana: 全文检索服务器 +可视化数据监控

ThreadPoolExecutor：线程池来实现异步操作，提高效率

OSS：文件存储服务

Knife4j（Swagger）：Api接口文档工具

Nginx：负载均衡

MySQL：关系型数据库

微信支付

微信小程序

Docker：容器技术

DockerFile：管理Docker镜像命令文本

后端环境搭建

p8-p10配置其他配置类

全局异常处理器

package com.atguigu.ssys.common.exception;

import com.atguigu.ssys.common.result.Result;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * 全局异常处理器，处理所有的异常，通过error方法，
 * 打印异常信息并返回错误结果类
 */
@ControllerAdvice
public class GlobalExceptionHandler {

//    将返回对象转成json数据，把所有异常进行处理
    @ResponseBody
    @ExceptionHandler(Exception.class)
    public Result error(Exception e){
        e.printStackTrace();
        return Result.fail(null);
    }

    /**
     * 自定义异常处理器
     * @param e
     * @return
     */
    @ResponseBody
    @ExceptionHandler(SsyxException.class)
    public Result Ssyxerror(SsyxException e){
        e.printStackTrace();
        return Result.build(null,e.getCode(),e.getMessage());
    }


}

自定义异常处理

package com.atguigu.ssys.common.exception;

import com.atguigu.ssys.common.result.ResultCodeEnum;

//自定义异常类
public class SsyxException extends RuntimeException {
    //异常状态码
    private Integer code;

    public Integer getCode() {
        return code;
    }

    public void setCode(Integer code) {
        this.code = code;
    }


    /**
     * 通过状态码和错误消息创建异常对象
     * @param message
     * @param code
     */
    public SsyxException(String message, Integer code) {
        super(message);
        this.code = code;
    }

    /**
     * 接收枚举类型对象
     * @param resultCodeEnum
     */
    public SsyxException(ResultCodeEnum resultCodeEnum) {
        super(resultCodeEnum.getMessage());
        this.code = resultCodeEnum.getCode();
    }

编写Swagger配置类

common模块添加依赖

<dependency>
    <groupId>com.github.xiaoymin</groupId>

p11-p13 前端环境，登录接口

前后端端口对应好后，写一下登录的控制器类，因为不是重点，所以先简单写一下，伪造基本信息，就好了。

package com.atguigu.ssyx.acl.controller;


import com.atguigu.ssys.common.result.Result;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.*;

import java.util.HashMap;
import java.util.Map;
import java.util.logging.Handler;


@Api(tags = "登录接口")
@RestController
@RequestMapping("/admin/acl/index")
public class IndexController {


    /**
     * 1、请求登陆的login
     */
    @ApiOperation("登录接口")
    @PostMapping("login")
    public Result login() {
        Map<String,Object> map = new HashMap<>();
//        用户在登录时，会创建一个token发给前端
        map.put("token","admin-token");
        return Result.ok(map);
    }


    /**
     * 2 获取用户信息
     */
    @ApiOperation("获取信息")
    @GetMapping("info")
    public Result info(){
        Map<String,Object> map = new HashMap<>();
//      暂时锚死了用户信息，封装成map返回给前端
        map.put("name","atguigu");
        map.put("avatar","https://wpimg.wallstcn.com/f778738c-e4f8-4870-b634-56703b4acafe.gif");
        return Result.ok(map);
    }

    /**
     * 3 退出
     */
    @ApiOperation("退出登录")
    @PostMapping("logout")
    public Result logout(){

        return Result.ok();
    }
}
