2019-07-29 站长为什么user的id是0了
逼格力



这个session里取到的值user的id是0,是因为我的idea是新版的原因还是因为jpa的原因.........
public Object cart(HttpSession session) {
        User user =(User)  session.getAttribute("user");

你不是说你2.1.5不怕吗 哈哈哈 在线翻车

how2j 答案时间:2019-07-31
换版本,风险很大

逼格力 答案时间:2019-07-31
应该是springboot的原因,站长是1,我是2.1.5,所以有的可能不一样

how2j 答案时间:2019-07-30
不应该呀,我的可运行项目也这样吗?



回答已经提交成功,正在审核。 请于 我的回答 处查看回答记录,谢谢
答案 或者 代码至少填写一项, 如果是自己有问题,请重新提问,否则站长有可能看不到





2019-06-17 购物车结算
咸鱼搬砖
点击购物车结算,url路径显示为buy?oiid=3&oiid=5 但是后台数组只能获取5,请问是什么原因? @GetMapping("forebuy") public Map<String,Object> buy(String[] oiid,HttpSession session)




1 个答案

how2j 答案时间:2019-06-18
不会吧,这样做就是为了接受多个参数,怎么会只有5呢

关于 实践项目-天猫整站Springboot-查看购物车页面 的提问

尽量提供截图代码异常信息,有助于分析和解决问题。 也可进本站QQ群交流: 881555796
提问尽量提供完整的代码,环境描述,越是有利于问题的重现,您的问题越能更快得到解答。
对教程中代码有疑问,请提供是哪个步骤,哪一行有疑问,这样便于快速定位问题,提高问题得到解答的速度
在已经存在的几千个提问里,有相当大的比例,是因为使用了和站长不同版本的开发环境导致的,比如 jdk, eclpise, idea, mysql,tomcat 等等软件的版本不一致。
请使用和站长一样的版本,可以节约自己大量的学习时间。 站长把教学中用的软件版本整理了,都统一放在了这里, 方便大家下载: http://how2j.cn/k/helloworld/helloworld-version/1718.html
