Question

我正在尝试制作一个简单的BBS，但我遇到了这个错误，

警告：org.springframework.web.servlet.PageNotFound - 找不到映射对于具有名称的DispatcherServlet中带有URI [/ board /]的HTTP请求 'appServlet'

我曾多次尝试解决此错误，但我失败了。我该如何解决这个错误？

这是我的web.xml，Controllerand和servlet-context。

我需要你的建议。

由于

Answer 1

尝试将web.xml文件中的<url-pattern>更改为：

<url-pattern>/*</url-pattern>

您是如何部署此应用程序的？作为board.war？

另外，为了让您知道，这是配置Spring MVC应用程序的一种非常古老的方式。 Spring有一些guides可用来展示现代方法。

Answer 2

代码中似乎缺少以下项目：

1。在servlet-context.xml中，添加

<context:component-scan base-package="com.onj" />
<mvc:annotation-driven />

替换 <beans:beans .....>与

<beans:beans xmlns="http://www.springframework.org/schema/mvc"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc.xsd">

2。为其中的方法添加@Controller注释和@RequestMappings，因为servlet-context.xml中没有找到控制器配置。

@Controller
public class BoardMultiController extends MultiActionController {

请求映射到list()方法：

@RequestMapping(value="/board", method = RequestMethod.GET)
public ModelAndView list(HttpServletRequest request,
            HttpServletResponse response) throws Exception {

警告：org.springframework.web.servlet.PageNotFound - 在DispatcherServlet中找不到带有URI [/ board /]的HTTP请求的映射，名称为'appServlet'
