SpringMVC and springmvc

SpringMVC framework setup steps:

1. Import the required jar package to the lib folder. 2. Configure web. xml. 3. Configure the springMVC core configuration file. 4. encode the Controller class.

Note: the source code of this project is imported into eclipse. After tomcat runs, enter http: // localhost: 8080/BrainTrain/welcome. jsp for testing.

Required jar package: http://pan.baidu.com/s/1i3QKYNF (Baidu cloud disk)

Project source code: http://pan.baidu.com/s/1kTWM9Rh; (Baidu cloud disk)

1. Configure web. xml

<? Xml version = "1.0" encoding = "UTF-8"?>

<Web-app xmlns: 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_2_5.xsd" id = "WebApp_ID" version = "2.5">

<Display-name> BrainTrain </display-name>

<Welcome-file-list>

<Welcome-file> index.html </welcome-file>

<Welcome-file> index. jsp </welcome-file>

</Welcome-file-list>

 

<Servlet>

<Servlet-name> springMVC </servlet-name>

<Servlet-class> org. springframework. web. servlet. DispatcherServlet </servlet-class>

<Init-param>

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

<! -- SpringMVC configuration file address. config is the package under src -->

<Param-value> classpath *: config/springAnnotation-servlet.xml </param-value>

</Init-param>

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

</Servlet>

 

<Servlet-mapping>

<Servlet-name> springMVC </servlet-name>

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

</Servlet-mapping>

</Web-app>

2. Spring MVC core configuration file: springAnnotation-servlet.xml

<? Xml version = "1.0" encoding = "UTF-8"?>

<Beans xmlns = "http://www.springframework.org/schema/beans"

Xmlns: context = "http://www.springframework.org/schema/context"

Xmlns: p = "http://www.springframework.org/schema/p"

Xmlns: mvc = "http://www.springframework.org/schema/mvc"

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-3.0.xsd

Http://www.springframework.org/schema/context

Http://www.springframework.org/schema/context/spring-context.xsd

Http://www.springframework.org/schema/mvc

Http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd>

<! -- Annotation scan package -->

<Context: component-scan base-package = "com. chuck. codeResource"> </context: component-scan>

<! -- Enable annotation -->

<Mvc: annotation-driven/>

<! -- Static resource access -->

<Mvc: resources location = "/img/" mapping = "/img/**"/>

<Mvc: resources location = "/js/" mapping = "/js/**"/>

<Mvc: resources location = "/staticHtml/" mapping = "/staticHtml/**"/>

<Bean id = "viewResolver" class = "org. springframework. web. servlet. view. InternalResourceViewResolver">

<Property name = "prefix" value = "/"> </property>

<Property name = "suffix" value = ". jsp"> </property>

</Bean>

</Beans>

3. Compile the Controller class

Package com. chuck. codeResource. user;

Import java. util. HashMap;

Import java. util. Map;

Import javax. servlet. http. HttpServletRequest;

Import javax. servlet. http. HttpServletResponse;

Import org. springframework. stereotype. Controller;

Import org. springframework. web. bind. annotation. RequestMapping;

Import org. springframework. web. bind. annotation. RequestMethod;

Import org. springframework. web. servlet. ModelAndView;

Import org. springframework. web. servlet. mvc. multiaction. MultiActionController;

@ Controller

@ RequestMapping ("/user ")

Public class LoginController extends MultiActionController {

@ RequestMapping ("/addUser ")

Public String addUser (HttpServletRequest request, HttpServletResponse response ){

System. out. println ("----- add ----");

String result = "this is addUser ";

Request. setAttribute ("result", result );

Return "/welcome ";

}

@ RequestMapping ("/delUser ")

Public String delUser (HttpServletRequest request, HttpServletResponse response ){

System. out. println ("----- delUser ----");

String result = "this is delUser ";

Request. setAttribute ("result", result );

Return "/welcome ";

}

@ RequestMapping ("/updateUser ")

Public String updateUser (HttpServletRequest request, HttpServletResponse response ){

System. out. println ("----- update ----");

String result = "this is updateUser ";

Request. setAttribute ("result", result );

Return "/welcome ";

}

}

4. Configure the accessed jsp page: welcome. jsp

<% @ Page language = "java" contentType = "text/html; charset = UTF-8"

PageEncoding = "UTF-8" %>

<% @ Taglib uri = "http://java.sun.com/jsp/jstl/core" prefix = "c" %>

<! DOCTYPE html PUBLIC "-// W3C // dtd html 4.01 Transitional // EN" "http://www.w3.org/TR/html4/loose.dtd">

<Html>

<Head>

<Meta http-equiv = "Content-Type" content = "text/html; charset = ISO-8859-1">

<Title> Insert title here </title>

</Head>

<Body>

The method for this execution is: $ {result}

<Form action = "user/addUser" method = "post">

<Input type = "submit" value = "post"/>

</Form>

</Body>

</Html>
