基于springmvc+mybatis的登录表单提交后404

关于服务器安装com组件读取表格的问题
服务器是win2008 r2 64位服务器,,数据库是sql2008 r2。程序是用C#开发的,有个excel表格读取功能,安装了office软件,用DCOM组件调用。 1、已经在服务器上设置了调用com组件,用的是“交互式用户”用户加了network service授权。 2、web.config中设置了超级管理员权限 <identity impersonate="true" userName="Administrator" password="123456"/> 问题 1、我试了n多办法,如果不用“交互式用户”,选了“启动用户 ”就无法读取excel信息。 只有"交互式用户 “才可以读取 . 2、只有服务器处于登录状态才可以读取出excel信息,如果不登录,还是无法读取信息。客户端还是无法读取,必须服务器的adeministrfator用户 处于登录状态 才可以读取 请高人帮我看看,非常感谢了。 核心文件:https://pan.baidu.com/s/1qYTgB2c

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过

神经⽹络可以计算任何函数的可视化证明

聊聊C语言和指针的本质
坐着绿皮车上海到杭州,24块钱,很宽敞,在火车上非正式地聊几句。 很多编程语言都以 “没有指针” 作为自己的优势来宣传,然而,对于C语言,指针却是与生俱来的。 那么,什么是指针,为什么大家都想避开指针。 很简单, 指针就是地址,当一个地址作为一个变量存在时,它就被叫做指针,该变量的类型,自然就是指针类型。 指针的作用就是,给出一个指针,取出该指针指向地址处的值。为了理解本质,我们从计算机模型说起...
为什么你学不过动态规划?告别动态规划,谈谈我的经验

Vue快速实现通用表单验证
本文开篇第一句话,想引用鲁迅先生《祝福》里的一句话,那便是:“我真傻,真的,我单单知道后端整天都是CRUD,我没想到前端整天都是Form表单”。这句话要从哪里说起呢?大概要从最近半个月的“全栈工程师”说起。项目上需要做一个城市配载的功能,顾名思义,就是通过框选和拖拽的方式在地图上完成配载。博主选择了前后端分离的方式,在这个过程中发现:首先,只要有依赖jQuery的组件,譬如Kendoui,即使使用...

面试官:关于Java性能优化,你有什么技巧
通过使用一些辅助性工具来找到程序中的瓶颈,然后就可以对瓶颈部分的代码进行优化。 一般有两种方案:即优化代码或更改设计方法。我们一般会选择后者,因为不去调用以下代码要比调用一些优化的代码更能提高程序的性能。而一个设计良好的程序能够精简代码,从而提高性能。 下面将提供一些在JAVA程序的设计和编码中,为了能够提高JAVA程序的性能,而经常采用的一些方法和技巧。 1.对象的生成和大小的调整。 J...

人脸生成黑科技:实现人脸转变特效,让人脸自动戴墨镜
上一节我们通过VAE网络完成了人脸生成效果。VAE网络一个特性是会把人脸编码成一个含有200个分量的向量,反过来说在特定分布范围内的含有200个分量的向量就对应一张人脸。由于向量之间可以进行运算,这就意味着我们把两张不同人脸A,B分布转换成两个不同向量z_A,z_B,然后我们使用向量运算例如z_AB = z_A *(1 - alpha) + z_B *alpha,就能将两个向量以一定比例合成一个新...
