2. Add Spring MVC Core Package

Second, configure the front-end controller in Web-info/web.xml Dispatcherservlet

1 <?XML version= "1.0" encoding= "Utf-8"?>2 <Web-appXmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xmlns= "Http://java.sun.com/xml/ns/javaee" 3 xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"ID= "webapp_id"version= "3.0">4     <Display-name>Dispatcherservlet</Display-name>5     <servlet>6         <!--Configure the front-end controller in the Spring MVC framework -7         <Servlet-name>Dispatcherservlet</Servlet-name>8         <!--This is the class address that points to the servlet that we want to register, with the package path -9         <Servlet-class>Org.springframework.web.servlet.DispatcherServlet</Servlet-class>Ten         <Init-param> One             <!--initializes the spring configuration file, loads the corresponding XML, and does not load the Applicationcontext.xml under/web-inf/. - A             <Param-name>Contextconfiglocation</Param-name> -             <!--specifies that the specific configuration file is Applicationcontext.xml, which is used by the current servlet to create the context - -             <Param-value>Classpath:applicationContext.xml</Param-value> the         </Init-param> -         <!--The servlet is loaded at startup, the number 1-5 is the servlet's boot order, and 1 is the highest - -         <Load-on-startup>1</Load-on-startup> -         <!--Load-on-startup must be put in the last - +     </servlet> -      +     <!--the access path used to configure the components we register - A     <servlet-mapping> at         <!--Specifies which servlet is configured - -         <Servlet-name>Dispatcherservlet</Servlet-name> -         <!--specifies which requests are blocked to the servlet - -         <Url-pattern>/</Url-pattern> -     </servlet-mapping> - </Web-app>

Third, under the resource configuration Applicationcontext.xml
