该文总结近期功能实现：
科室库出库：接受前端传入数据后，根据数量完成stock与stock_detail库的修改。
接收数据，调用outFromBranch方法
@ApiOperation("移出科室库")
@RequestMapping(value = "/outFromBranch", method = RequestMethod.POST)
@ResponseBody
public CommonResult outFromBranch(@RequestBody ReagentStock stock) {
int count = stockService.outFromBranch(stock);
return CommonResult.success(1);
}
改变quantuty，调用updateByPrimaryKeySelective并传入
public int outFromBranch(ReagentStock stock){
long Quantity=stock.getQuantity();
long Number=stock.getoutNumber();
stock.setQuantity(Quantity-Number);
stockMapper.updateByPrimaryKeySelective(stock);
return stockMapper.outFromBranch(stock.getStockNo(),Number);
}
调用数据库并写入（需判断if，否则容易出问题）
<update id="updateByExampleSelective" parameterType="map">
update reagent_stock
<set>
<if test="record.id != null">
id = #{record.id,jdbcType=BIGINT},

delete_by = #{record.deleteBy,jdbcType=VARCHAR},
</if>
</set>
<if test="_parameter != null">
<include refid="Update_By_Example_Where_Clause" />
</if>
调用outFromBranch
<delete id="outFromBranch" parameterType="jp.co.nss.hrm.backend.model.ReagentStock">
delete from reagent_stock_detail
where stock_no = ${stock_no}
limit ${Number}
完成detail库操作，根据数量删除
