Question

这是我得到的错误。即使应用程序从index.jsp页面开始，但无法移动到login.jsp页面。

这是项目结构。

这是分派器Servlet。[{]] 3

这是web.xml文件。

这是index.jsp文件，具有格式元素=“ / KashmirConnect / signUp”的属性操作，将其带到@RequestMapping（“ / signUp”）

这是具有一种方法的控制器类

Answer 1

您可以按照此说明

1。将index.jsp移至“视图”文件夹中

2. write your web.xml like this

<?xml version="1.0" encoding="UTF-8"?>
        <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xmlns="http://java.sun.com/xml/ns/javaee"
                 xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
                 id="WebApp_ID" version="2.5">

            <servlet>
                <servlet-name>DispatcherServlet</servlet-name>
                <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
                <load-on-startup>1</load-on-startup>
            </servlet>
            <servlet-mapping>
                <servlet-name>DispatcherServlet</servlet-name>
                <url-pattern>/</url-pattern>
            </servlet-mapping>


            <context-param>
                <param-name>contextConfigLocation</param-name>
                <param-value>WEB-INF/DispatcherServlet-servlet.xml</param-value>
            </context-param>
            <listener>
                <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
            </listener>
        </web-app>

3. Now in controller class write a method like 

     @RequestMapping("/")
       public ModelAndView index()
        {
          ModelAndView modelAndView = new ModelAndView("index");
          return modelAndView;
        }

您可以通过将pom.xml替换为此
