In both of the posts they have mentioned to add this code

在他们提到的两个帖子中添加此代码

The 404 error was due to the fact that I was missing context-param tag.
So I added this code to my web.xml

404 错误是由于我缺少上下文参数标记。
所以我将此代码添加到我的 web.xml

<context-param> 
<param-name>contextConfigLocation</param-name> 
<param-value>classpath*:META-INF/spring/applicationContext*.xml</param-value> 
</context-param>

After adding it I got the following error:

添加后，我收到以下错误：

javax.servlet.ServletException: Servlet.init() for servlet sort threw exception
    org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102)
    org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286)...

java.lang.NoSuchFieldError: APPLICATION_CONTEXT_ID_PREFIX
org.springframework.web.servlet.FrameworkServlet.createWebApplicationContext(FrameworkServlet.java:430)
org.springframework.web.servlet.FrameworkServlet.createWebApplicationContext(FrameworkServlet.java:458)...

Getting this error I found that I was mixing a jar file in my lib folder. From some input I found that the culprit jar was spring2.5.6.jar.
So, I deleted the spring2.5.6.jar.

得到这个错误我发现我在我的 lib 文件夹中混合了一个 jar 文件。从一些输入中我发现罪魁祸首 jar 是 spring2.5.6.jar。
所以，我删除了spring2.5.6.jar。

The above steps did the trick... Thanks to all the inputs.

上面的步骤成功了……感谢所有的投入。

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

There's you problem ... you have not got a correctly named, and located applicationContext.xml. Where are you saving the applicationContext.xml, have you named it correctly ?

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