java - No WebApplicationContext found : no ContextLoaderListener registered? 然后404错误

Question

我发现错误是因为在我的jsp中添加了如下几行

<form:form></form:form>

我检查了这两个与我的错误相关的帖子。

No WebApplicationContext found: no ContextLoaderListener registered?

spring security No WebApplicationContext found

在他们提到的两个帖子中添加此代码

<listener>
   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>  

像这样在我的 web.xml 中添加此代码后

<?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" id="WebApp_ID" version="2.5">

    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

  <servlet>
        <servlet-name>sort</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>sort</servlet-name>
        <url-pattern>*.html</url-pattern>
    </servlet-mapping>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

我收到 HTTP 状态 404 - 错误并且我的项目不可用(这是服务器说的)。

我的构建路径中的相关 jar 是:1.springwebmvc3.0.3.jar、2.spring2.5.6.jar，我还有 spring-form.tld 文件。

如何解决这个错误？
我应该再添加一些 jar 文件吗？
我正在使用 STS 2.9.2 版本进行开发。以下是来自控制台的启动日志。

Caused by: java.io.FileNotFoundException: Could not open ServletContext resource [/WEB-INF/applicationContext.xml]

你有问题......你没有正确命名和定位applicationContext.xml。您将 applicationContext.xml 保存在哪里，您是否正确命名了它？
