应该是目录和路径不对应吧，要么就是相对路径错误

: chris688 是的是的，应该放，我也放了，就是转不过去，貌似是配置文件的问题; 大约 2 年之前回复

: 凌晨_野吹 是不是list。jsp存放的位置不对啊应该放在view文件夹下; 大约 2 年之前回复

: chris688 abc就是个代号，我是这么理解的，controller接到index.jsp发来的“abc”信号，运行getEmps（）方法，得到“list”，然后不就应该找list.jsp页面吗？; 大约 2 年之前回复

我@RequestMapping("tologin.do")里边都是直接写请求你那个list在WEB-INf/views下放着？我看你视图解析器那样配的，是的话，在WEB-INF下的jsp不能直接访问

: guoao1 回复chris688: 你不是说你直接输入报404？; 大约 2 年之前回复

: chris688 前缀后缀都注明了，“list”不是通过controller获取的吗？; 大约 2 年之前回复

: chris688 list.jsp是在WEB-INF/views下，但是springmvc里的视图解析器不是告诉程序去按照这个地址找吗？; 大约 2 年之前回复

如果你配置了拦截器那么在WEB-IF下的jsp你是不能直接访问的，你可以访问一下那个list.jsp如果还是404那么可能是一个很搞笑的原因那就是你的项目
并没有部署到服务器上哈哈

: chris688 回复xxuncle: 这个abc我理解就是代号，index.jsp发的所有请求都会被controller获取，它会解析这个请求，也就是abc，然后去运行相应的方法，我是这么理解的; 大约 2 年之前回复

: xxuncle 回复chris688: 如果不是同级目录那么你的这个路径配置就是错误的; 大约 2 年之前回复

: xxuncle 回复chris688: 你访问的这个abc是和index.jsp在同级目录下吗？; 大约 2 年之前回复

: chris688 没有，我不是直接访问啊，是通过index.jsp的<jsp：foword page=“/abc”>访问的; 大约 2 年之前回复

web.xml里面有没有配置action的拦截如*.do,*.action，有的话给forward 的/abc加上

: 我是一只小小小小小鸟 回复chris688: NoSuchBeanDefinitionException具体是哪个Bean，你可以在log里确定一下扫描到没有，现在是跟debug有关，run可以debug不行吗？; 大约 2 年之前回复

: chris688 朋友，之前运行没遇到异常，刚才debug了一下，报NoSuchBeanDefinitionException; 大约 2 年之前回复

路径是没有问题的，就是你的springMvc的配置问题，想要跳转，首先加上拦截你的.do

<context:component-scan base-package="com.hat.action"></context:component-scan>

配置拦截器路径

你的controller的返回值是个list，应该是某个jsp页面，如果不想跳转，那就return一个json的空值，或者success

首先说http://localhost:8080/crud/index.jsp 你的index.jsp是不是放错地方了有些地方客户端是访问不到的不如WEB-INF 下就是访问不到的

ssm下，多个超链接如何发送ajax请求然后将页面跳转: 在ssm框架下，多个超链接如何发送ajax请求然后将页面跳转到 ``` <jsp:include page="#"></jsp:include> ``` 如下代码： ![图片说明](https://img-ask.csdn.net/upload/201904/06/1554535838_475529.png) 不懂如何弄，求解

electron应用到底是什么？: 刚刚接触electron,好多东西没弄明白。 electron的前后端到底怎么划分，看了文档，前端肯定是用html+js+css实现，但是后端是啥我却一直找不到相关资料，它的后台逻辑是用node.js写吗？举个例子来说，我现在有个javaweb项目，ssm框架写的，我要怎么把它改成electron应用，我的前端各种jsp页面可以直接用，可以界面之间的跳转怎么实现，因为跳转需要根据后台传回的数据判断后实现？后台用java写的各种逻辑怎么办，从mysql数据库存取数据的各种操作在electron项目里怎么体现？向各位大佬请教一下

使用ssm框架开发，一直跳转不到controller层。。。不报错。。。: ``` <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <c:set var="ctx" value="${pageContext.request.contextPath }"></c:set> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <link rel="stylesheet" href="${ctx}/css/style.css" type="text/css" media="all"/> <title>请假的实战记录</title> <style type="text/css"> body{ background-color: #fff; } </style> </head> <body> <center> <div style="width:350px;"> <form id="myForm" action="${ctx}/lr/lrAdd">----这就是跳转的地址 <h1>添加请假记录</h1> <table> <tr> <td>姓名</td> <td><input type="text" name="name" datatype="s6-16" errormsg="姓名长度为6-16位" nullmsg="请输入姓名"/> </td> </tr> <tr> <td>请假时间</td> <td> <input type="text" name="time" onclick="WdatePicker();" nullmsg="请输入时间"/> </td> </tr> <tr> <td>请假原因</td> <td> <textarea name="reason" datadype="s1-200" errormsg="最长字数为200" nullmsg="请假原因"></textarea> </td> </tr> <tr> <td></td> <td> <input type="submit" name="" value="提交"/>   <input type="reset" name="" value="清空"/> </td> </tr> </table> </form> </div> </center> <scritpt type="text/javascript" src="${ctx}/js/jquery-1.9.1.min.js"></scritpt> <scritpt type="text/javascript" src="${ctx}/js/Validform_v5.3.2_min.js"></scritpt> <scritpt type="text/javascript" src="${ctx}/js/My97DatePicker/WdatePicker.js"></scritpt> <scritpt type="text/javascript" src="${ctx}/js/My97DatePicker/calendar.js"></scritpt> <script type="text/javascript"> $(function(){ $("#myFrom").Validform(); }); </script> </body> </html> ``` ``` package com.sxt.controller; import javax.servlet.http.HttpServletRequest; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import com.sxt.pojo.Leaver; import com.sxt.service.LrService; import com.sxt.util.DateUtil; @Controller() @RequestMapping("/lr") public class AddController { @Autowired LrService lrService; @RequestMapping("/lrAdd") public String lrAdd(Leaver leaver,HttpServletRequest request){ //接收前台传送的数据 String name = request.getParameter("name"); String time = request.getParameter("time"); String reason = request.getParameter("reason"); //设置时间模式 String patten ="yyyy-MM-dd"; //将信息整合成一个对象进行传递 Leaver lea = new Leaver(name, DateUtil.str2Date(time, patten), reason); //对后台数据进行调用 int count = lrService.addLea(lea); if(count > 0){ return "redirect:/index"; }else{ return "redirect:/add"; } } } ``` 控制台不报错，F12页面信息老是显示的是404，就进不了Controller层，老是显示 lrAdd好像有问题。。 ![图片说明](https://img-ask.csdn.net/upload/201710/16/1508149012_161177.png) 控制台不报错就是浏览器就成这样了。。。很伤啊。。一下午了，搞不定。。

ssm中Controller跳转到jsp中，不能显示参数值问题: 这是spring的配置： ```   <bean id="defaultViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">  <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> ``` 以下是我的jsp代码： ``` <%@ page contentType="text/html;charset=UTF-8" language="java" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <html> <head> <title>ssm ${test}</title> </head> <body> <table width="100%" border=1> <tr> <td>商品名称</td> <td>商品价格</td> <td>商品描述</td> </tr> <c:forEach var="item" items="${itemList}"> <tr> <td>${item.name}</td> <td>${item.price}</td> <td>${item.detail}</td> </tr> </c:forEach> </table> </body> </html> ``` controller代码： ``` @RequestMapping("/findAllItem") public ModelAndView showItem(HttpSession session){ List<Item> itemList=itemService.findAllItem(); for(int i=0;i<itemList.size();i++){ Item item=itemList.get(i); System.out.println("Item:[ id= "+item.getId()+" | name= "+item.getName()+" | price= "+item.getPrice()+" | detail= "+item.getDetail()+" ]"); } session.setAttribute("aa","success"); //创建ModelAndView的对象 ModelAndView mv=new ModelAndView(); mv.setViewName("index"); mv.addObject("test","测试"); mv.addObject("itemList",itemList); return mv; } ``` 项目运行后可以正常跳转到对应的jsp，但是页面没有值，如图 ![图片说明](https://img-ask.csdn.net/upload/201710/12/1507821054_327718.png) 请问，这是什么原因？？？？
