Question

我正在学习Spring MVC，我建立了第一个＆＃34; hello world＆＃34;例。但我无法访问该页面。它说＆＃34;原始服务器没有找到目标资源的当前表示，或者不愿意透露它存在。＆＃34;我正在使用Tocat 9.0（我也试过Tomcat 8仍然无法正常工作）。所以这是我的代码

控制器：

package com.emin.springdemo.mvc;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/")
    public String showPage() {

        return "main-menu";
    }
}

jsp文件：

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!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=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
    <h2>Spring MVC Demo</h2>
</body>
</html>

servlet.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <context:component-scan base-package="com.emin.springdemo.mvc" />

    <!-- Step 4: Add support for conversion, formatting and validation support -->

    <!-- Step 5: Define Spring MVC view resolver -->
    <bean
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/view/" />
        <property name="suffix" value=".jsp" />
    </bean>

</beans>

web.xml：

[![<?xml version="1.0" encoding="UTF-8"?>

    id="WebApp_ID" version="3.1">

    <display-name>spring-mvc-demo</display-name>

    <!-- Spring MVC Configs -->

    <!-- Step 1: Configure Spring MVC Dispatcher Servlet -->
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-mvc-demo-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- Step 2: Set up URL mapping for Spring MVC Dispatcher Servlet -->
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

我知道网站上有重复的主题。我试过它们也没有达到解决方案。

问题可能是短划线，因为它不是有效的Java标识符尝试重命名jsp并返回fileName。

未找到您从浏览器请求的页面，因此您需要在以下模式中添加URL：

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/'
    },
    {
      path: '/login',
      component: Login
    },
    {
      path: '/trucker',
      component: Trucker,
      meta: { requiresAuth: true, truckerAuth : true, dispatchAuth: false },
      children: [
                {
                  path: '/loads',
                  component: Loads
                }
            ]
    },
    {
      path: '/dispatch',
      component: Dispatch,
      meta: { requiresAuth: true, truckerAuth : false, dispatchAuth: true },
      children: [
                {
                  path: '/drivers',
                  component: Drivers,
                  children: [
                      {
                        path: 'calendar',
                        component: Calendar
                      }
                  ]
                }
                ]
    },

  ]
})

尝试映射URL，然后重新启动服务器。

找不到Tomcat 404 Http
