Question

我正在尝试使用Spring MVC开发一个基本的登录应用程序。当我尝试运行该项目时，它在启动时给出404（Resourse not found）。这是我的代码：

弹簧调度-servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:mvc="http://www.springframework.org/schema/mvc" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans 
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">
<mvc:default-servlet-handler />
<bean id="HandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />
<bean name="/welcome.html" class="com.sumanth.org.HelloController" />

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix">
        <value>/WEB-INF</value>
    </property>
    <property name="suffix">
        <value>*.jsp</value>
    </property>
</bean>

这是web.xml：

<?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_3_0.xsd"
id="WebApp_ID" version="3.0">
<display-name>logInSpring</display-name>
<welcome-file-list>
<welcome-file>HelloPage.jsp</welcome-file>

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>spring-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

控制器：

package com.sumanth.org;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class HelloController extends AbstractController {

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest request,
    HttpServletResponse response) throws Exception {
        ModelAndView modelandview = new ModelAndView("HelloPage");
        modelandview.addObject("WelcomeMessage","hi");

        return modelandview;
    }
}

我坚信有一些配置问题。请让我知道如何解决这个问题。尝试在stackoverflow和其他网站上看到各种帖子，但没有任何帮助我。

Answer 1

您的servlet映射似乎是错误的。应该是spring-dispatcher-servlet而不是spring-dispatcher 试试这个：

   <servlet>
    <servlet-name>spring-dispatcher-servlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring-dispatcher-servlet.xml</param-value>
    </init-param>
</servlet>

<servlet-mapping>
    <servlet-name>spring-dispatcher-servlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Answer 2

检查文件夹结构后.. 所有弹簧罐应该复制到Web-INF中的lib文件夹中并从那里导入

找不到Spring mvc资源
