Environment: Myeclipse10.6+jdk7+tomcat7
Library: spring4.1.6
1. Create a project
Configure Maven-related properties in Myeclipse, and create a Maven Web project testSpringWeb.
Deploy the project to tomcat and start it.
Visit http://localhost:8080/testSpringWeb to verify the base environment.
2. Add dependency library
Add springmvc related dependencies in pom.xml.

<jackson.version>1.9.13</jackson.version>
<spring.version>4.1.6.RELEASE</spring.version>

3. Configure web.xml
Add the following configuration in web.xml, load spring and springmvc servlet at startup
<!-- spring -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:root-context.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- encoding filter -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<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>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- spring mvc -->
<servlet>
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:servlet-context.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
When spring starts, root-context.xml is loaded, and springmvc servlet loads servlet-context.xml, and parses all paths under /.
4. Spring configuration
Create a configuration file root-context.xml under src/main/resources with the following contents:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd" default-autowire="byName" default-lazy-init="true"> </beans>
Don't use bean configuration for now.
5.springmvc configuration
Create a configuration file servlet-context.xml under src/main/resources, the content is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
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-3.0.xsd"
default-autowire="byName" default-lazy-init="true">
<!-- If the current request is "/", forward to "/helloWorld" -->
<mvc:view-controller path="/" view-name="forward:/helloWorld"/>
<!-- Static resource mapping -->
<mvc:resources location="/resources/" mapping="/resources/**" />
<!-- Resolves view names to protected .jsp resources within the /WEB-INF/views
directory -->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
<property name="order" value="1" />
</bean>
<!-- @ResponseBody -->
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter">
<property name="messageConverters">
<list>
<bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter" />
</list>
</property>
</bean>
<!-- controller -->
<import resource="resolvers-context.xml" />
</beans>
Create a configuration file resolvers-context.xml under src/main/resources with the following contents:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
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-3.0.xsd"
default-autowire="byName" default-lazy-init="true">
<!-- controller -->
<bean name="/helloWorld" class="com.sunbin.test.testSpring.web.controller.HelloWorldController"/>
</beans>
Configure a controller with an address of /helloWorld, the viewer page directory is /WEB-INF/jsp/, and define the home page to jump to the controller (must not have index.jsp/index.html)
6. Hello World
creates a Controller.java class
package com.sunbin.test.testSpring.web.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
public class HelloWorldController implements Controller {
public ModelAndView handleRequest(HttpServletRequest arg0,
HttpServletResponse arg1) throws Exception {
// TODO Auto-generated method stub
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("message", "hello world!");
modelAndView.setViewName("helloWorld");
return modelAndView;
}
}
Create helloWorld.jsp in the src/main/webapp/WEB-INF/jsp directory
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!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=UTF-8">
<title>Insert title here</title>
</head>
<body>${message }
</body>
</html>
The Controller simply outputs the hello world! string on the page.
Delete the index.jsp of the home page so that the <mvc:view-controller path="/" view-name="forward:/helloWorld"/> configuration takes effect.
7. After testing the Hello World deployment project and starting tomcat, you can see the hello world! information by visiting http://localhost:8080/testSpringWeb/helloWorld http://localhost:8080/testSpringWeb/
through a browser
