2个回答

no matching editors or conversion strategy found//没有发现匹配的编辑器或版本策略。
可能是版本不匹配。
你看看你的配置有没有错误,没有错误就大概是这个问题了

'urlMapping' 这没有在web-config.xml中配置bean

整合Spring+SpringMVC+Hibernate时,无法进入控制层
整合Spring+SpringMVC+Hibernate时,启动正常,可以打开登录页面,但是进行登录时,无法进入controller层,而且不报错,只输出三行日志。 DispatcherServlet with name 'springMVC' processing POST request for [/SSH/user/login.do] No mapping found for HTTP request with URI [/SSH/user/login.do] in DispatcherServlet with name 'springMVC' Successfully completed request 意思大概是找不到路径,但应该不是路径的问题,如果路径有问题,页面上message会显示有问题的路径,而不是什么都没有。 HTTP Status 404 - type Status report message description The requested resource is not available.

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

一个读研让我损失了一百万的真实故事
关注我!只要10分钟,包你学会数据分析 毕业后,应该就业还是考研? 我刚出国留学那会儿,就惊讶的发现,外国local95%都不会选择读研 他们说,硕士学费很贵,时间宝贵,老板不认,所以很费 当几乎所有人都是本科学历时,硕士学历反而像个异类 在老板眼里,三年硕士远远不如3年的工作经验实用 他们甚至专门为拒绝高学历者发明了一个词,叫overoccupie...

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
动态规划难吗?说实话,我觉得很难,特别是对于初学者来说,我当时入门动态规划的时候,是看 0-1 背包问题,当时真的是一脸懵逼。后来,我遇到动态规划的题,看的懂答案,但就是自己不会做,不知道怎么下手。就像做递归的题,看的懂答案,但下不了手,关于递归的,我之前也写过一篇套路的文章,如果对递归不大懂的,强烈建议看一看:为什么你学不会递归,告别递归,谈谈我的经验 对于动态规划,春招秋招时好多题都会用到动态...
程序员一般通过什么途径接私活?
二哥,你好,我想知道一般程序猿都如何接私活,我也想接,能告诉我一些方法吗? 上面是一个读者“烦不烦”问我的一个问题。其实不止是“烦不烦”,还有很多读者问过我类似这样的问题。 我接的私活不算多,挣到的钱也没有多少,加起来不到 20W。说实话,这个数目说出来我是有点心虚的,毕竟太少了,大家轻喷。但我想,恰好配得上“一般程序员”这个称号啊。毕竟苍蝇再小也是肉,我也算是有经验的人了。 唾弃接私活、做外...

压测学习总结(1)——高并发性能指标:QPS、TPS、RT、吞吐量详解
一、QPS,每秒查询 QPS:Queries Per Second意思是“每秒查询率”,是一台服务器每秒能够相应的查询次数,是对一个特定的查询服务器在规定时间内所处理流量多少的衡量标准。互联网中,作为域名系统服务器的机器的性能经常用每秒查询率来衡量。 二、TPS,每秒事务 TPS:是TransactionsPerSecond的缩写,也就是事务数/秒。它是软件测试结果的测量单位。一个事务是指一...

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...

GitHub 标星 1.6w+,我发现了一个宝藏项目,作为编程新手有福了!
大家好,我是 Rocky0429,一个最近老在 GitHub 上闲逛的蒟蒻… 特别惭愧的是,虽然我很早就知道 GitHub,但是学会逛 GitHub 的时间特别晚。当时一方面是因为菜,看着这种全是英文的东西难受,不知道该怎么去玩,另一方面是一直在搞 ACM,没有做一些工程类的项目,所以想当然的以为和 GitHub 也没什么关系(当然这种想法是错误的)。 后来自己花了一个星期看完了 Pyt...
