通过对比 入库申请-＞入库审核流程 与 直接入库 代码实现，解决前者误修改stock_info表is_in=1或2数据的bug

入库申请->入库审核流程：

提交按键定义位置：src\views\purchase\rurchase\RurchaseAdd.vue

确认物品已入库

后台API地址：/cos/rurchase-request/rurchasePut

后台服务方法名：cc.mrbird.febs.cos.service.impl.RurchaseRequestServiceImpl#rurchasePut

后台java文件路径：D:\code\javaspringboot\dinningroomsupply\SuppliesManagementSystem\backend\src\main\java\cc\mrbird\febs\cos\service\impl\RurchaseRequestServiceImpl.java

存在的bug：80~82行，更新 stock_info表的当前物品库存总数，条件为限定is_in=0，导致is_in=1（入库）和is_in=2（出库）的历史出入库数据都被修改

stockInfoService.update(Wrappers.lambdaUpdate()

.set(StockInfo::getAmount, stockInfo.getAmount()+item.getAmount())        

.set(StockInfo::getPrice, stockInfo.getPrice())        

.eq(StockInfo::getName, stockInfo.getName())); //注意，这里更新条件用的是name不是id

从控制台打印的sql语句可以看出，更新语句的条件有误：

2023-11-22 16:26:31 | INFO  | http-nio-9527-exec-10 | p6spy | 2023-11-22 16:26:31 | 耗时 8 ms | SQL 语句： UPDATE stock_info SET amount=14,price=11.00 WHERE name = 'test';
