springmvc启动报错， No mapping found for HTTP request with URI

Question

我搭建springmvc工程，我想拦截所有的请求，在web.xml中这样配置：

<?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"
         xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
         version="2.5">

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

  <!-- 加载springMVC配置 -->
  <servlet>
    <servlet-name>springServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/spring-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>springServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <error-page>
    <error-code>404</error-code>
    <location>/resourceNotFound</location>
  </error-page>

</web-app>

spring-config.xml配置

        <!--<property name="defaultEncoding" value="UTF-8"/>-->
    <!--</bean>-->
</beans>

启动的时候，报错：

No mapping found for HTTP request with URI [/resourceNotFound] in DispatcherServlet with name 'springServlet'
请问是什么原因？

Answer 1

<error-page>
    <error-code>404</error-code>
    <location>/resourceNotFound</location>
  </error-page>

你给配的404页面不存在吧，指向一个已存在的静态页面，或controller中配上/resourceNotFound试试
