About the "Could not open ServletContext resource [/web-inf/applicationcontext.xml]" solution

Problem description, I configured the following in the Web. xml file

<servlet>    <servlet-name>dispatcherServlet</servlet-name>    <servlet-class >org.springframework.web.servlet.dispatcherservlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:spring.xml </param-value>    </init-param>    <load-on-startup>ten</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>dispatcherservlet</ servlet-name>    <url-pattern>/*</url-pattern>  </servlet-mapping> 

But the error.

Note that, in fact, the focus is a word, that is, could not open ServletContext resource [/web-inf/applicationcontext.xml], the anomaly is also very obvious, filenotexception, Unable to open ServletContext resource file.

Let's start with the official search for clues and take a look at spring's official documentation, which can be found in the chapters of the Web:

If the <context-parameter> element named Contextconfigloction is not deliberately specified, then spring's Contextloderlistener listener is/web-inf/ Go down and look for and load this file named Applicationcontext.xml under this directory.

So it should be specified in the Web. xml file

Works correctly after modification
