Java代碼實(shí)現(xiàn)商品的審核問題？

你這個(gè)只是一個(gè)方法，而且是數(shù)據(jù)分析，應(yīng)該放在服務(wù)層，而且你這里還沒有返回值，怎么告訴控制層？

目前創(chuàng)新互聯(lián)已為千余家的企業(yè)提供了網(wǎng)站建設(shè)、域名、虛擬主機(jī)、網(wǎng)站托管、企業(yè)網(wǎng)站設(shè)計(jì)、瀍河網(wǎng)站維護(hù)等服務(wù)，公司將堅(jiān)持客戶導(dǎo)向、應(yīng)用為本的策略，正道將秉承"和諧、參與、激情"的文化，與客戶和合作伙伴齊心協(xié)力一起成長，共同發(fā)展。

第一：服務(wù)層：

public String audit(Long spuId,String status) {

Spu spu =new Spu();

spu.setId(spuId);

spu.setStatus(status);

if ("1".equals(status)){//審核通過

spu.setIsMarketable("1");//自動(dòng)上架

}else{

如果不是，怎么怎么樣

}

spuMapper.updateByPrimaryKeySelective(spu);

return 某個(gè)狀態(tài)值

}

第二：控制層：

前端傳進(jìn)來參數(shù)，調(diào)用服務(wù)層方法，返回前端

System.out.println("請(qǐng)輸入商品價(jià)格：");

}

System.out.println("");

for(int i= 0;iprice.length;i++){

totalPrice+=price[i];

}

System.out.println("商品總價(jià)格是："+totalPrice);
