java中数据库的时间字段和jsp页面显示的不一样

数据库的时间和页面的时间显示不一样,数据库的时间是:2015-05-13 12:24:03 显示到页面上:1431491043000,求解

得到的数据 应该是 日期的毫秒数· 可以通过 new java.Date(毫秒数) 转化成 Java里面的Date 应该就可以了

需要对格式进行转换,转换代码:

protected static final String DATE_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss";

    public static String format(java.util.Date date,String dateFormat) {
         if(date == null) {
            return null;
        }
         DateFormat df = new SimpleDateFormat(dateFormat);
         return df.format(date);
    }

你是不是当作整数或者timestamp输出了。
看下你的代码

你接时间的字段用String类型

请问怎样在一个JSP页面上显示有记录的信息

就是说在一个jsp上实现对数据库的添加功能之后,想在下次添加数据 的时候如果在电话号码那一栏输入了数据库中已经存在的号码,那就会 将这条号码的全部信息都调出来然后自动填入到别的框中,只需要改 不一样的就好,使用的是jeecg,希望能有代码可以参考

数据库接受不到前台传过来的数据

我遇到一个问题,问题是:我要实现的是在页面里面将金额变成手动输入的,然后在另一个页面也是这个,另一个页面保存了以后查看详细就与数据,但是这个就不行,查看了以后变成了0,我看jsp里面金额的logic都是一样内容,调用的方法里面也是一样的内容,跟踪了数据库之后数据库有金额这个字段但是值是0,请问可以帮我解决这个问题吗?在线等。。。。

怪异问题!sql在pl/sql中执行结果与java jdbc执行结果不一致

做一查询系统(struts2+myeclipse+tomcat+oracle9),一般先在pl/sql中测试sql语句,无问题后在action中使用oracle thin模式连接数据库,执行sql语句,然后将查询结果存入HashMap后输出至jsp页面。 出现如下怪异问题: 1、在pl/sql中测试sql语句时结果正常。结果中有6个字段,其中两个字段为count()函数统计出的数值。 2、将在pl/sql中测试过的sql语句写入struts2的action中,通过jdbc thin模式执行,查询结果与pl/sql中测试结果不一致。 count()函数统计的那两个字段的值不一致,暂未发现规律。数值接近,互有高低。 在struts2的action中执行sql语句前,先打印sql语句,打印语句与pl/sql中测试语句一样,查询结果一致。 在action中执行sql语句后在将rs(RecordSet)存入HashMap前,输出rs内容,count()统计出的数值结果已经不一致。 该系统中类似查询功能有几个,实现方式方法相同,唯独这个出现pl/sql和jdbc执行同一句sql结果后部分字段数值不一致的诡异情况! 烦请大家帮助分析、支招!不胜感激!!

javaEE连接mysql数据库,然后通过映射把数据显示到网页上,可是没报错却网页没有内容。

Git 实用技巧

这几年越来越多的开发团队使用了Git,掌握Git的使用已经越来越重要,已经是一个开发者必备的一项技能;但很多人在刚开始学习Git的时候会遇到很多疑问,比如之前使用过SVN的开发者想不通Git提交代码为什么需要先commit然后再去push,而不是一条命令一次性搞定; 更多的开发者对Git已经入门,不过在遇到一些代码冲突、需要恢复Git代码时候就不知所措,这个时候哪些对 Git掌握得比较好的少数人,就像团队中的神一样,在队友遇到 Git 相关的问题的时候用各种流利的操作来帮助队友于水火。 我去年刚加入新团队,发现一些同事对Git的常规操作没太大问题,但对Git的理解还是比较生疏,比如说分支和分支之间的关联关系、合并代码时候的冲突解决、提交代码前未拉取新代码导致冲突问题的处理等,我在协助处理这些问题的时候也记录各种问题的解决办法,希望整理后通过教程帮助到更多对Git操作进阶的开发者。 本期教程学习方法分为“掌握基础——稳步进阶——熟悉协作”三个层次。从掌握基础的 Git的推送和拉取开始,以案例进行演示,分析每一个步骤的操作方式和原理,从理解Git 工具的操作到学会代码存储结构、演示不同场景下Git遇到问题的不同处理方案。循序渐进让同学们掌握Git工具在团队协作中的整体协作流程。 在教程中会通过大量案例进行分析,案例会模拟在工作中遇到的问题,从最基础的代码提交和拉取、代码冲突解决、代码仓库的数据维护、Git服务端搭建等。为了让同学们容易理解,对Git简单易懂,文章中详细记录了详细的操作步骤,提供大量演示截图和解析。在教程的最后部分,会从提升团队整体效率的角度对Git工具进行讲解,包括规范操作、Gitlab的搭建、钩子事件的应用等。 为了让同学们可以利用碎片化时间来灵活学习,在教程文章中大程度降低了上下文的依赖,让大家可以在工作之余进行学习与实战,并同时掌握里面涉及的Git不常见操作的相关知识,理解Git工具在工作遇到的问题解决思路和方法,相信一定会对大家的前端技能进阶大有帮助。

150讲轻松搞定Python网络爬虫

【为什么学爬虫?】 &nbsp; &nbsp; &nbsp; &nbsp;1、爬虫入手容易,但是深入较难,如何写出高效率的爬虫,如何写出灵活性高可扩展的爬虫都是一项技术活。另外在爬虫过程中,经常容易遇到被反爬虫,比如字体反爬、IP识别、验证码等,如何层层攻克难点拿到想要的数据,这门课程,你都能学到! &nbsp; &nbsp; &nbsp; &nbsp;2、如果是作为一个其他行业的开发者,比如app开发,web开发,学习爬虫能让你加强对技术的认知,能够开发出更加安全的软件和网站 【课程设计】 一个完整的爬虫程序,无论大小,总体来说可以分成三个步骤,分别是: 网络请求:模拟浏览器的行为从网上抓取数据。 数据解析:将请求下来的数据进行过滤,提取我们想要的数据。 数据存储:将提取到的数据存储到硬盘或者内存中。比如用mysql数据库或者redis等。 那么本课程也是按照这几个步骤循序渐进的进行讲解,带领学生完整的掌握每个步骤的技术。另外,因为爬虫的多样性,在爬取的过程中可能会发生被反爬、效率低下等。因此我们又增加了两个章节用来提高爬虫程序的灵活性,分别是: 爬虫进阶:包括IP代理,多线程爬虫,图形验证码识别、JS加密解密、动态网页爬虫、字体反爬识别等。 Scrapy和分布式爬虫:Scrapy框架、Scrapy-redis组件、分布式爬虫等。 通过爬虫进阶的知识点我们能应付大量的反爬网站,而Scrapy框架作为一个专业的爬虫框架,使用他可以快速提高我们编写爬虫程序的效率和速度。另外如果一台机器不能满足你的需求,我们可以用分布式爬虫让多台机器帮助你快速爬取数据。 &nbsp; 从基础爬虫到商业化应用爬虫,本套课程满足您的所有需求! 【课程服务】 专属付费社群+每周三讨论会+1v1答疑
