After the above configuration, it shows that the basic development environment has been set up, now to start the SPRINGMVC Web site development. 1, web.xml configuration

Open the Web.xml file under Src\main\webapp\web-inf\, and slightly update the Web.xml version, you can support some of the more advanced syntax, as follows:?

1 2 3 4 5 6 7 8 9

? XML version = "1.0" encoding = "UTF-8"?> < Web-app xmlns = "Http://xmlns.jcp.org/xml/ns/javaee" xmlns: xsi = "Http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation = "Http://xmlns.jcp.org/xml/ns/javaee http: Xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd "Version =" 3.1 "> < display-name >springmvcdemo W EB application</display-name > </web-app >

Add a servlet to <web-app>:
?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

? xml  Version = "1.0"   encoding = "UTF-8"?> < web-app  xmlns = "Http://xmlns.jcp.org/xml/ns/javaee" & nbsp;         xmlns:xsi = "Http://www.w3.org/2001/XMLSchema-instance"           xsi:schemalocation = "Http://xmlns.jcp.org/xml/ns/javaee  http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd "           Version = "3.1" >        < display-name >SpringMVCDemo Web  application</display-name >        < servlet >           < Servlet-name >mvc-dispatcher</servlet-name >           < Servlet-class >org.springframework.web.servlet.dispatcherservlet</Servlet-class >           < Load-on-startup >1</Load-on-startUp >      </servlet >        < servlet-mapping >  &nbsp ;       < Servlet-name >mvc-dispatcher</servlet-name >           < Url-pattern >/</Url-pattern >      </ servlet-mapping > </web-app >

The servlet name is Mvc-dispatcher (the name can be modified) to intercept the request (Url-pattern to/, to intercept all requests) and to be processed by the background controller of spring MVC. This configuration is required.

In order to be able to process the Chinese POST request, then configure a encodingfilter to avoid the POST request in Chinese garbled situation:?

1 2 3 4 5 6 7 8 9 10 11 12 13 14-15 16

< filter >      < filter-name >encodingfilter</filter-name >    & nbsp < Filter-class >org.springframework.web.filter.characterencodingfilter</Filter-class >       < Init-param >          < param-name >encoding</ Param-name >          < param-value >utf-8</Param-value >      </init-param >      < init-param >     & nbsp;    < Param-name >forceencoding</param-name >           < Param-value >true</param-value >      </init-param > </Filter & Gt < filter-mapping >      < filter-name >encodingfilter</filter-name >       < Url-pattern >/*</Url-pattern > </filter-mapping >

At this point, the Web.xml configuration is complete.
2, xxx-servlet.xml configuration

After Web.xml is configured, you need to create a new mvc-dispatcher-servlet.xml in the Web.xml sibling (-servlet the servlet name defined in the servlet above):

After you create the XML file, click on the Configure in the upper-right corner to appear on the Setup frameworks interface and click OK, so that IntelliJ idea identifies the SPRINGMVC configuration file:

Mvc-dispatcher-servlet.xml files are as follows:?

1 2 3 4 5 6

? XML version = "1.0" encoding = "UTF-8"?> < beans xmlns = "Http://www.springframework.org/schema/beans" x Mlns:xsi = "Http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation = "Http://www.springframework.org/schema /beans http://www.springframework.org/schema/beans/spring-beans.xsd "> </beans >

MVC Framework has model, view, controller three parts. Model generally for some basic Java Bean,view for the corresponding page display, controller used to process the request of the website.

Create a new package to save the controller in Src\main\java:

Create a new Java class Maincontroller in the controller package (the name is not fixed and can be arbitrarily taken), and modify the following:

?

package  com.gaussic.contr Oller;   import  Org.springframework.stereotype.Controller; import  org.springframework.web.bind.annotation.RequestMapping; import  Org.springframework.web.bind.annotation.RequestMethod;  /**   *&NBSP;CREATED&NBSP;BY&NBSP;DZKAN&NBSP;ON&NBSP;2016/3/8.   * @Controller public  class  maincontroller {       @RequestMapping ( value =  "/",  method = re
