Spring-MVC!

Come to work early in the morning, and there is no network! Nothing can be done!

I remembered reading some spring-MVC documents yesterday.

Configure spring-MVC.

Since there is no network, only official spring documents are available.

1. Create a basic project and then click OK.

2. Introduce the spring-MVC development kit. According to the development documentation, only three packages are required.

The following is a spring document:

Copy libraries'WEB-INF/lib'

First create'lib'Directory in'war/WEB-INF'Directory. Then, from the spring distribution, copyspring.jar
(Fromspring-framework-2.5/dist) Andspring-webmvc.jar(Fromspring-framework-2.5/dist/modules) To the new
'war/WEB-INF/lib'Directory. Also, copy
commons-logging.jar(From
spring-framework-2.5/lib/jakarta-commons) To'war/WEB-INF/lib'Directory. These jars will be deployed to the server and they are also used during the build process.

3. modify web. xml and add a Servlet as follows:

<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4"         xmlns="http://java.sun.com/xml/ns/j2ee"         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"         xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee          http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" >  <servlet>    <servlet-name>springapp</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <load-on-startup>1</load-on-startup>  </servlet>  <servlet-mapping>    <servlet-name>springapp</servlet-name>    <url-pattern>*.htm</url-pattern>  </servlet-mapping>  <welcome-file-list>    <welcome-file>      index.jsp    </welcome-file>  </welcome-file-list></web-app>

4. Create a WEB-INF under the springmvc-servlet.xml. The name here is your project plus servlet.

Then configure the controller you need in the document.

 

<? XML version = "1.0" encoding = "UTF-8"?> <Beans xmlns = "http://www.springframework.org/schema/beans" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi: schemalocation = "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd"> <! -- The application context definition for the springapp dispatcherservlet --> <! -- The controller and the hello.htm path will pass through this controller. It is a bit like configuring action in struts. XML in struts2. Each path corresponds to a cotroller. there is no action concept in srping-MVC, only cotroller. --> <bean name = "/hello.htm" class = "springapp. web. hellocontroller "/> </beans>

5. Create a controller and create hello. jsp under webroot.

package springmvc.web;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.apache.commons.logging.Log;import org.apache.commons.logging.LogFactory;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;public class HelloController implements Controller{protected final Log logger = LogFactory.getLog(getClass());public ModelAndView handleRequest(HttpServletRequest arg0,HttpServletResponse arg1) throws Exception {logger.info("run hello Controller");return new ModelAndView("hello.jsp");}}

Enter

Http: // localhost: 8080/springmvc/hello.htm. The hello. jsp page is displayed.
