Spring3 MVC Introduction:
1. Spring MVC is a Web component of the spring framework that can develop Web engineering
2. Able to integrate well with other frameworks (Struts2)
3. Spring MVC is a servlet-centric, distributed request to the controller via Dispatcherservlet
4. Dispatcherservlet is a fully integrated spring IOC container that can use other spring features
5. Spring3 MVC Support Annotation Technology
6. Spring3 can support JAP2.0 very well.
Then let's write an example:
1. Prepare the required tools and jar packages:
(1). JDK 1.7
(2). apache-tomcat-7.0.52
(3). Eclipse-javaee version of
(4). Jar Required:
Commons-logging-1.1.1.jar
Jstl-1.2.jar
Org.springframework.asm-3.0.0.release.jar
Org.springframework.beans-3.0.0.release.jar
Org.springframework.context-3.0.0.release.jar
Org.springframework.core-3.0.0.release.jar
Org.springframework.expression-3.0.0.release.jar
Org.springframework.web-3.0.0.release.jar
Org.springframework.web.servlet-3.0.0.release.jar
Jar:http://pan.baidu.com/s/1eqvxlom
2. Create a Dynamic Web project, and select the server, select the version of the servlet (2.5)
3. Copy the required jar to the webcontent---web-inf> lib folder
4.Spring Controller Class
Create a control class for Spring MVC and process the request, print a word ' Spring MVC example ', then we create the package Com.li.controller and then create a class Hellocontroller.java underneath the package, Add code to this class. Specify @controller and @requestmapping ("/test") in the Hellocontroller class. @Controller: When spring scans the package, it is represented as a bean that processes the request. @RequestMapping ("/test"): The request URL address should be processed
1 PackageCom.li.controller;2 3 ImportOrg.springframework.stereotype.Controller;4 Importorg.springframework.web.bind.annotation.RequestMapping;5 ImportOrg.springframework.web.servlet.ModelAndView;6 7 @Controller8 Public classHellocontroller {9 Ten@RequestMapping ("/test") One PublicModelandview Test () { AString str= "Spring MVC Sample"; - return NewModelandview ("message", "str", str); - } the}Hellocontroller.java
5. Create a JSP
Create a JSP make a request: index.jsp
Create a JSP display message: message.jsp
Send a request to hellocontroller with a hyperlink inside the index.jsp, and return to message.jsp to display STR's information

6.Spring MVC mapping in Web. xml
Main definition: Org.springframework.web.servlet.DispatcherServlet
You need to add the following configuration to the Web. XML configuration file in the project:
1 <servlet>2 <Servlet-name>Spring</Servlet-name>3 <Servlet-class>4 Org.springframework.web.servlet.DispatcherServlet5 </Servlet-class>6 <Load-on-startup>1</Load-on-startup>7 </servlet>8 <servlet-mapping>9 <Servlet-name>Spring</Servlet-name>Ten <Url-pattern>/</Url-pattern> One </servlet-mapping>View Code
7.Spring configuration file
Note the name of the servlet in the previous step of the <servlet-name> tag in Web. Xml.
After initialization of the Dispatcherservlet, a file name is found in Web-inf [servlet-name]-servlet.xml
In this example, you should find the spring-servlet.xml
Create a spring configuration file under Web-inf, with the file name: Spring-servlet.xml, and copy the following to the file:
1 <?XML version= "1.0" encoding= "UTF-8"?>2 <Beansxmlns= "Http://www.springframework.org/schema/beans"3 Xmlns:xsi= "Http://www.w3.org/2001/XMLSchema-instance"XMLNS:AOP= "HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP"4 Xmlns:tx= "Http://www.springframework.org/schema/tx"Xmlns:context= "Http://www.springframework.org/schema/context"5 xsi:schemalocation=" 6 Http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/ Spring-beans-3.0.xsd7 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd8 Http://www.springframework.org/schema/context http://www.springframework.org/schema/context/ Spring-context-3.0.xsd9 HTTP://WWW.SPRINGFRAMEWORK.ORG/SCHEMA/AOP http://www.springframework.org/schema/aop/spring-aop-3.0.xsd " Ten Default-autowire= "ByName"> One <Context:component-scanBase-package= "Com.li.controller"/> A <BeanID= "Viewresolver" - class= "Org.springframework.web.servlet.view.UrlBasedViewResolver"> - < Propertyname= "Viewclass" the value= "Org.springframework.web.servlet.view.JstlView"/> - < Propertyname= "prefix"value="/"/> - < Propertyname= "suffix"value= ". jsp"/> - </Bean> + </Beans>Spring-servlet.xml
