在当今数字化时代，高效的商品进销存管理系统对于企业运营至关重要。本文将深入介绍基于 JavaWeb 的 Spring Boot 商品进销存系统，涵盖其技术架构、核心代码实现以及关键功能模块。
技术架构概览
本系统采用了一系列先进的技术，构建了一个稳定、高效且易于维护的架构。核心技术栈包括：
后端：Spring + Spring Boot + MyBatis + Maven
前端：Vue
数据库：MySQL
开发工具：Jdk1.8、Mysql、HBuilderX（或 Webstorm）、Eclispe（或 IntelliJ IDEA、MyEclispe、Sts）
适用
课程设计，大作业，毕业设计，项目练习，学习演示等

接口返回数据格式
系统定义了统一的接口返回数据格式，确保数据传输的一致性和可理解性。
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;import java.io.Serializable;@Data
@ApiModel(value = "接口返回对象", description = "接口返回对象")
public class Result<T> implements Serializable {private static final long serialVersionUID = 1L;@ApiModelProperty(value = "成功标志")private boolean success = true;@ApiModelProperty(value = "返回处理消息")private String message = "操作成功！";@ApiModelProperty(value = "返回代码")private Integer code = 0;@ApiModelProperty(value = "返回数据对象 data")private T result;@ApiModelProperty(value = "时间戳")private long timestamp = System.currentTimeMillis();public Result() {}public Result success(String message) {this.message = message;this.code = CommonConstant.SC_OK_200;this.success = true;return this;}public static Result ok() {Result r = new Result();r.setSuccess(true);r.setCode(CommonConstant.SC_OK_200);r.setMessage("成功");return r;}public static Result ok(String msg) {Result r = new Result();r.setSuccess(true);r.setCode(CommonConstant.SC_OK_200);r.setMessage(msg);return r;}public static Result ok(Object data) {Result r = new Result();r.setSuccess(true);r.setCode(CommonConstant.SC_OK_200);r.setResult(data);return r;}public static Result error(String msg) {return error(CommonConstant.SC_INTERNAL_SERVER_ERROR_500, msg);}public static Result error(int code, String msg) {Result r = new Result();r.setCode(code);r.setMessage(msg);r.setSuccess(false);return r;}public Result error500(String message) {this.message = message;this.code = CommonConstant.SC_INTERNAL_SERVER_ERROR_500;this.success = false;return this;}public static Result noauth(String msg) {return error(CommonConstant.SC_JEECG_NO_AUTHZ, msg);}
}
用户信息控制器
用户信息控制器负责处理与用户相关的请求，如权限验证、文件上传等。
