1. Increase Spring Support

To create a new Web project, add the following jar package:

Commons-logging-1.2.jar Spring-aop-4.2.5.release.jar Spring-aspects-4.2.5.release.jar Spring-beans-4.2.5.release.jar

Spring-context-4.2.5.release.jar Spring-context-support-4.2.5.release.jar Spring-core-4.2.5.release.jar Spring-expression-4.2.5.release.jar

Spring-instrument-4.2.5.release.jar Spring-instrument-tomcat-4.2.5.release.jar Spring-jdbc-4.2.5.RELEASE.jar Spring-jms-4.2.5.release.jar

Spring-messaging-4.2.5.release.jar Spring-orm-4.2.5.release.jar Spring-oxm-4.2.5.release.jar Spring-test-4.2.5.release.jar

Spring-tx-4.2.5.release.jar Spring-web-4.2.5.release.jar Spring-webmvc-4.2.5.release.jar

Spring-webmvc-portlet-4.2.5.release.jar Spring-websocket-4.2.5.release.jar

2. Configure the front-end controller Dispatcherservlet

Configure the Web. xml file (add Dispatcherservlet configuration)

<! --Define spring MVC's Front controller--

<servlet>

<servlet-name>springmvc</servlet-name>

<sevlet-class>org.springframework.web.servlet.DispacherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/spring-config.xml</param-value>

</init-param>

<load-on-startup>1</load-on-stratup>

</servlet>

<servlet-mapping>

<servlet-name>springmvc</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

3, configure the controller SPRINGMVC

Configure the configuration file for Springmvc Spring-config.xml

<beans>

　　<!--configure handle, map "Hello" request--

<beanname= "/hello" class= "Org.fkit.conttroler.HelloController"/>

　　<!--processing Mapper looks up the bean as a URL and needs to specify the name (that is, the URL) when configuring handle.

<bean class= "org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"/>

　　<!--Simplecontrollerhandleradapter is a processor adapter that implements the Handleradapter interface for all processor adapters--

<bean class= "Org.springframework.web.servler.mvc.SimpleControllerHandlerAdapter"/>

　　<!--configuration View Resolver--

<bean class= "Org.springframework.web.servlet.view.InternalResourceViewResolver"/>

</beans>

4, the Controller class implementation

The Controller class must implement the Controller interface to handle/hello requests. (or use @controller annotations directly)

public class Hellocontroller implements controller{

Private static final Log logger = Logfactory.getlog (HELLOCONTROLLER.CALSS);

@Override

Public Modelandview HandleRequest (httpservletrequest request,httpservletresponse response) throws exception{

Logger.info ("HandleRequest is called");

Modelandview mv = new Modelandview ();

Mv.addobject ("message", "Hello world!");

Mv.setviewname ("/web-inf/content/welcome.jsp");

return MV;

}

}

5. View Page

<body>

<!--page to access the message--> passed by the controller

${requestscope.message}

</body>

6. Test Application
