return “ok”?
这个不对吧
response.getWriter().print(“ok”);
return null;
你改成这样!

debug 下 看看哪地方空指针了。应该某个值 是空了
at org.apache.jsp.WEB_002dINF.common.message_jsp._jspService(message_jsp.java:86)
重点看下这个JSP页面

dashabenmao data: "roleNames=" + roleNames, 你这JSON 格式 不对。。 这地方要放JSON格式。你这不对。后台所以取不到你的之 你需要放 unction sonclick(){ var roleNames=$("#roleName").val(); var data={ roleNames:roleNames }; $.ajax({ type: "POST", url: "<%=basePath %>user/userInfo!SaveUserName.action", data: data, success: function(msg){ if(msg=="OK"){ document.forms[0].submit(); }else{ alert(msg) } } }); }

apache-tomcat-6.0.14\work\Catalina\localhost\工程名称\对应路径下的jsp编译的java类,查看对应的行,判断什么参数有问题。

很明显 空指针了 debug调试 看哪里空了

明明是jsp报错,搞什么经典错误,看看jsp编译后的java类吧,找到对应的行,看看是什么代码,再找到jsp中对应的代码,修改一下。

data: "roleNames=" + roleNames, 改成data:{"roleNames":roleNames},试试

既然是ajax请求,那肯定是struts配置有问题了,ajax请求的话,返回类型一般要用json类型,根据你的错误来看,转到message.jsp去了,难道你是通过jsp来返回ajax数据的?把你的struts配置,message.jsp贴出来看看

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
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
大学四年自学走来,这些私藏的实用工具/学习网站我贡献出来了
大学四年,看课本是不可能一直看课本的了,对于学习,特别是自学,善于搜索网上的一些资源来辅助,还是非常有必要的,下面我就把这几年私藏的各种资源,网站贡献出来给你们。主要有:电子书搜索、实用工具、在线视频学习网站、非视频学习网站、软件下载、面试/求职必备网站。 注意:文中提到的所有资源,文末我都给你整理好了,你们只管拿去,如果觉得不错,转发、分享就是最大的支持了。 一、PDF搜索网站推荐 对于大部

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发

通俗易懂地给女朋友讲:线程池的内部原理
餐厅的约会 餐盘在灯光的照耀下格外晶莹洁白,女朋友拿起红酒杯轻轻地抿了一小口,对我说:“经常听你说线程池,到底线程池到底是个什么原理?”我楞了一下,心里想女朋友今天是怎么了,怎么突然问出这么专业的问题,但做为一个专业人士在女朋友面前也不能露怯啊,想了一下便说:“我先给你讲讲我前同事老王的故事吧!” 大龄程序员老王 老王是一个已经北漂十多年的程序员,岁数大了,加班加不动了,升迁也无望,于是拿着手里

为啥国人偏爱Mybatis,而老外喜欢Hibernate/JPA呢?
关于SQL和ORM的争论,永远都不会终止,我也一直在思考这个问题。昨天又跟群里的小伙伴进行了一番讨论,感触还是有一些,于是就有了今天这篇文。 声明:本文不会下关于Mybatis和JPA两个持久层框架哪个更好这样的结论。只是摆事实,讲道理,所以,请各位看官勿喷。 一、事件起因 关于Mybatis和JPA孰优孰劣的问题,争论已经很多年了。一直也没有结论,毕竟每个人的喜好和习惯是大不相同的。我也看

“狗屁不通文章生成器”登顶GitHub热榜,分分钟写出万字形式主义大作
一、垃圾文字生成器介绍 最近在浏览GitHub的时候,发现了这样一个骨骼清奇的雷人项目,而且热度还特别高。 项目中文名:狗屁不通文章生成器 项目英文名:BullshitGenerator 根据作者的介绍,他是偶尔需要一些中文文字用于GUI开发时测试文本渲染,因此开发了这个废话生成器。但由于生成的废话实在是太过富于哲理,所以最近已经被小伙伴们给玩坏了。 他的文风可能是这样的: 你发现,
程序员:我终于知道post和get的区别
IT界知名的程序员曾说:对于那些月薪三万以下,自称IT工程师的码农们,其实我们从来没有把他们归为我们IT工程师的队伍。他们虽然总是以IT工程师自居,但只是他们一厢情愿罢了。 此话一出,不知激起了多少(码农)程序员的愤怒,却又无可奈何,于是码农问程序员。 码农:你知道get和post请求到底有什么区别? 程序员:你看这篇就知道了。 码农:你月薪三万了? 程序员:嗯。 码农:你是怎么做到的? 程序员:

Android 9.0系统新特性,对刘海屏设备进行适配
其实Android 9.0系统已经是去年推出的“老”系统了,这个系统中新增了一个比较重要的特性,就是对刘海屏设备进行了支持。一直以来我也都有打算针对这个新特性好好地写一篇文章,但是为什么直到拖到了Android 10.0系统都发布了才开始写这篇文章呢?当然,一是因为我这段时间确实比较忙,今年几乎绝大部分的业余时间都放到写新书上了。但是最主要的原因并不是这个,而是因为刘海屏设备的适配存在一定的特殊性

碎片化的时代,如何学习
今天周末,和大家聊聊学习这件事情。 在如今这个社会,我们的时间被各类 APP 撕的粉碎。 刷知乎、刷微博、刷朋友圈; 看论坛、看博客、看公号; 等等形形色色的信息和知识获取方式一个都不错过。 貌似学了很多,但是却感觉没什么用。 要解决上面这些问题,首先要分清楚一点,什么是信息,什么是知识。 那什么是信息呢? 你一切听到的、看到的,都是信息,比如微博上的明星出轨、微信中的表情大战、抖音上的...
