要看你的controller的代码,参考:https://blog.csdn.net/qq_36769100/article/details/71746449

qq_35239073 controller 就是 一个 方法 return 'index'

试一下其他页面能不能直接访问,可能是被拦截了

检查请求的URL是否会被springmvc拦截

再添加个配置:

springmvc UrlFilenameViewController

你的路径中的/a/index不是index.jsp的,是requestmapping的路径值,然后你return的才是jsp名。

你应该贴出Crotroller代码,检查类和方法头上的注释,然后检查返回的viewname与实际jsp位置是否对应。

你访问的是/a/index.jsp
你配置的是index.jsp ,肯定找不到,报404了
你访问localhost/index.jsp

那你在WEB-INF/views这个目录下面有index.jsp这个文件吗?它就说你这个文件找不到啊

springmvc + tiles 局部刷新页面中的document.ready事件没有触发
We get a page with 2 columns layout (also include header and footer). In the left part, it is a tree. And the right part is the content which will be changed based on the click event on the leaf of the left tree. We use springmvc 4.0.6.RELEASE and apache tiles 3.0.5 and we adopt the solution provided on link: http://stackoverflow.com/questions/17719176/noclassdeffounderror-while-using-ajaxurlbasedviewresolver-in-spring-mvc-3. And we really get it work. Below are my solution: reportTemplate.jsp define the common overview layout. <%@ taglib uri="http://tiles.apache.org/tags-tiles" prefix="tiles"%> <jsp:include page="../pages/common/import.jsp"></jsp:include> <body class="body-white root1200"> <tiles:insertAttribute name="header" /> <div class="g-content wrapper clearfix "> <tiles:insertAttribute name="menu" /> <div class="m-content"> <div class="iframe-inner"> <tiles:insertAttribute name="main" /> <div id="fragment"></div> </div> </div> </div> <tiles:insertAttribute name="footer" /> </body> </html> layout.xml defines each part of the layout. <tiles-definitions> <definition name="reportTemplate" template="/WEB-INF/templates/reportTemplate.jsp"> <put-attribute name="header" value="/WEB-INF/pages/common/header.jsp" /> <put-attribute name="menu" value="/WEB-INF/pages/common/menu.jsp" /> <put-attribute name="main" value="" /> <put-attribute name="footer" value="/WEB-INF/pages/common/footer.jsp" /> </definition> </tiles-definitions> views.xml when click the tree, we use the second definition which has null configuration for "main" attribute. <definition name="admin/configuration/listReports" extends="reportTemplate"> <put-attribute name="main" value="/WEB-INF/pages/admin/configuration/listReports.jsp" /> </definition> <definition name="admin/configuration/listReports-m" extends="reportTemplate"> </definition> Controller @RequestMapping(value = "/admin/report/ajax/listReports", method = RequestMethod.GET) public String ajaxListReport(Map<String, Object> model, @RequestParam(value="from",required=false) String from) { model.put("report", new Report()); if(from != null && !from.equalsIgnoreCase("headMenu")){ return "admin/configuration/listReports-m"; } else { return "admin/configuration/listReports"; } } in listReports.jsp, we use jquery datatable plugin and the table will be initialized when document.ready event fired. $(document).ready(function() { table = $('#example').dataTable({ "bProcessing" : true, "bServerSide" : true, "iDisplayLength" : 10, "bSort" : true, "dataType" : "json", "sAjaxSource" : "ajax/getReport?repName="+$('#repName').val(), "sAjaxDataProp": "aaData", ... }); } ); It works properly when use the 1st definition which include "main" part. When we click on the leaf of the tree, the page loaded, but the data of the jquery datatable not load. onClick: function(data2) { console.log(data2); $.ajax({ type : "GET", beforeSend : function(request) { request.setRequestHeader("Accept", "text/html;type=ajax"); }, url : "/fiba/admin/report/ajax/listReports?fragments=main", processData : false, success : function(msg) { $('div[id="fragment"]').empty().append(msg); } }); } We think the reason is that ajax call will not trigger doucment.ready event on listReport.jsp. How can we resolve this issue? Or is there any simple solution for partial refresh of the complex layout? On the listReport.jsp we also have some actions need be triggerred.
SSM框架中,怎么通过controller实现页面的跳转?
今天接触SSM框架的第四天,后台Mybatis生成dao、entity和mapper后,测试成功,能够正常读写数据库了,但是,在加入页面之后,通过controller不能实现页面的跳转,特求助~~ 访问情况: ![图片说明](https://img-ask.csdn.net/upload/201811/27/1543304296_872148.png) 点击跳转后, ![图片说明](https://img-ask.csdn.net/upload/201811/27/1543304328_484707.png) 出现404的错误,个人认为,可能是没有找到controller 代码: messageController.java ``` @Controller public class messageController { @RequestMapping("/message/go") public String gotest(){ return "second"; } } ``` index.jsp ``` <%@page contentType="text/html; charset=UTF-8" language="java" %> <html> <head> <title>首页</title> </head> <body> <h2>Hello World!</h2> <a href="/message/go">点击跳转</a> <p id="test">Hello World!</p> <button type="button" onclick="selectUser()">onclick test</button> </body> </html> ``` reach.jsp ``` <%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>跳到这里了</title> </head> <body> 跳转成功!!!

SpringMVC 项目,JSP 视图解析器 直接jsp返回为html,配置错误?
Controller采用注解的方式,代码为: ```@Controller @RequestMapping("/request") public class TestController { @Autowired UIFieldService fieldService; @RequestMapping("/testController")//method=RequestMethod.GET,value= public String getString(){ //@RequestBody String str,HttpServletResponse response, Model model System.out.println("hello world"); return "test"; } } ``` dispatcherServlet.xml配置中jsp视图解析器配置: ``` <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name = "prefix" value="/WEB-INF/views/"></property> <property name = "suffix" value = ".jsp"></property> <property name="order" value="1"></property> </bean> ``` 感觉这个jsp视图解析器配置了没用,这个文件中还必须要配置<mvc:default-servlet-handler/>,否则提示错误。同时web.xml增加了下面一项: ``` <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>*.jsp</url-pattern> </servlet-mapping> ``` 请求路径: http://devtest.milan.com:8082/test_c3p0/service/request/testController _返回结果: ![图片说明](https://img-ask.csdn.net/upload/201707/20/1500538613_302933.png)

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。

程序员接私活怎样防止做完了不给钱?

Python十大装B语法
Python 是一种代表简单思想的语言,其语法相对简单,很容易上手。不过,如果就此小视 Python 语法的精妙和深邃,那就大错特错了。本文精心筛选了最能展现 Python 语法之精妙的十个知识点,并附上详细的实例代码。如能在实战中融会贯通、灵活使用,必将使代码更为精炼、高效,同时也会极大提升代码B格,使之看上去更老练,读起来更优雅。

介绍 最近跟着公司的大佬开发了一款IM系统,类似QQ和微信哈,就是聊天软件。我们有一部分业务逻辑是这样的 if (msgType = "文本") { // dosomething } else if(msgType = "图片") { // doshomething } else if(msgType = "视频") { // doshomething } else { // doshom...
Nginx 原理和架构
Nginx 是一个免费的,开源的,高性能的 HTTP 服务器和反向代理,以及 IMAP / POP3 代理服务器。Nginx 以其高性能,稳定性,丰富的功能,简单的配置和低资源消耗而闻名。 Nginx 的整体架构 Nginx 里有一个 master 进程和多个 worker 进程。master 进程并不处理网络请求,主要负责调度工作进程:加载配置、启动工作进程及非停升级。worker 进程负责处...
“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

【技巧总结】位运算装逼指南
位算法的效率有多快我就不说,不信你可以去用 10 亿个数据模拟一下,今天给大家讲一讲位运算的一些经典例子。不过,最重要的不是看懂了这些例子就好,而是要在以后多去运用位运算这些技巧,当然,采用位运算,也是可以装逼的,不信,你往下看。我会从最简单的讲起,一道比一道难度递增,不过居然是讲技巧,那么也不会太难,相信你分分钟看懂。 判断奇偶数 判断一个数是基于还是偶数,相信很多人都做过,一般的做法的代码如下...
为什么要学数据结构?
一、前言 在可视化化程序设计的今天,借助于集成开发环境可以很快地生成程序,程序设计不再是计算机专业人员的专利。很多人认为,只要掌握几种开发工具就可以成为编程高手,其实,这是一种误解。要想成为一个专业的开发人员,至少需要以下三个条件: 1) 能够熟练地选择和设计各种数据结构和算法 2) 至少要能够熟练地掌握一门程序设计语言 3) 熟知所涉及的相关应用领域的知识 其中,后两个条件比较容易实现,而第一个...
