Developing SPRINGMVC with annotations

1. importing the jar Package

Commons-logging-1.2.jar

Spring-aop-4.3.6.release.jar

Spring-beans-4.3.6.release.jar

Spring-context-4.3.6.release.jar

Spring-context-support-4.3.6.release.jar

Spring-core-4.3.6.release.jar

Spring-expression-4.3.6.release.jar

Spring-web-4.3.6.release.jar

Spring-webmvc-4.3.6.release.jar

Taglibs-standard-compat-1.2.5.jar

Taglibs-standard-impl-1.2.5.jar

Taglibs-standard-jstlel-1.2.5.jar

Taglibs-standard-spec-1.2.5.jar

2.web.xml Configuration

<?XML version= "1.0" encoding= "UTF-8"?><Web-appXmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"xmlns= "Http://java.sun.com/xml/ns/javaee"xsi:schemalocation= "Http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"version= "3.0">  <Display-name>01springmvc_mvc</Display-name>  <servlet>    <Servlet-name>Springmvc</Servlet-name>    <Servlet-class>Org.springframework.web.servlet.DispatcherServlet</Servlet-class>    <Init-param>        <Param-name>Contextconfiglocation</Param-name>        <Param-value>Classpath:mvc.xml</Param-value>    </Init-param>    <Load-on-startup>1</Load-on-startup>  </servlet>    <servlet-mapping>    <Servlet-name>Springmvc</Servlet-name>    <Url-pattern>*.do</Url-pattern>  </servlet-mapping>  <welcome-file-list>    <Welcome-file>index.jsp</Welcome-file>  </welcome-file-list></Web-app>

Attention:

 <  init-param         >  <  param-name  >  contextconfiglocation</ param-name  >   <  param-value  >  classpath: Mvc.xml</ param-value  >  </ init-param  >  

Indicates the configuration file location (src/mvc.xml) Focus of MVC

3.Controller

 Public class Hellocontroller {    @RequestMapping ("/hello")    public  Modelandview Hello ( HttpServletRequest req, HttpServletResponse resp) {        new  Modelandview ();         // encapsulate the data        to be displayed in the view Mav.addobject ("msg", "Hello Springmvc");         // View name        Mav.setviewname ("Hello");         return Mav;}    }

4.SPRINGMVC Configuration
