Java 加载索引或第一页时出现HTTP状态404

我是春季MVC的新手。我正在开发我的第一个项目。如果我运行我的项目，会得到一个错误HTTP状态404。没有部署错误

我的web.xml如下所示

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4"
         xmlns="http://java.sun.com/xml/ns/j2ee"

上下文配置位置
/WEB-INF/applicationContext.xml
org.springframework.web.context.ContextLoaderListener
调度员

还有我的调度器servlet

</beans>

应用程序servlet是

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <bean id="dataSource"

    <bean id="UserDao" class="com.innovaturelabs.multicast.dao.UserDao" />
    <bean id="sessionFactory"

      p:packagesToScan="com.innovaturelabs.spring.web.entity"
      p:hibernateProperties-ref="hibernateProperties" />

</beans>

只要将dispatcher servlet映射到“/”位置，所有请求都可以通过它

<context:component-scan base-package="com.innovaturelabs.multicast.controller" use-default-filters="false">
    <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>

另一件事是，您应该将jsp文件与

InternalResourceViewResolver

一起使用，而不是使用html

   <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
         p:prefix="/WEB-INF/"
         p:suffix=".jsp">
    </bean>

---

Html文件应该位于静态文件夹中，并由mvc映射：resource tag

404是一个客户端错误-“我找不到该页面”您在访问哪个url时运行什么上下文？访问日志怎么说？html文件放在WEB-INF/view/index.html中。tomcat日志不会产生任何错误消息您的JAR文件名是什么，您可以发布Maven POM吗？您使用什么url尝试访问它？？你的回答是不够的
<mvc:resources mapping="/resources/**"
               location="/resources/html/"
<mvc:resources mapping="/resources/**"
               location="/resources/html/"
