Build the Spring MVC 4 development environment eight steps away

Spring MVC as a springframework product, since the birth of the day, has been the attention of a wide range of developers, now spring MVC development in Java is thriving, and now if developers say, do not understand spring MVC, may be people laughed. Sensational words will not say, first tell you how to build the spring MVC development environment.

(i) Working environment preparation:

JDK 1.7

Eclipse Kepler

Apache Tomcat 8.0

(ii) Create a new Maven project in Eclipse, in the archetype type, select "Maven-archetype-webapp".

(iii) configuration of Pom.xml.

<project xmlns= "http://maven.apache.org/POM/4.0.0"  xmlns:xsi= "http://www.w3.org/2001/ Xmlschema-instance "  xsi:schemalocation=" http://maven.apache.org/POM/4.0.0 http:// Maven.apache.org/maven-v4_0_0.xsd ">  <modelVersion>4.0.0</modelVersion>   <groupid>com.favccxx.favsoft</groupid>  <artifactid>favspringmvcrestful</ artifactid>  <packaging>war</packaging>  <version>0.0.1-snapshot</ Version>  <name>favspringmvcrestful maven webapp</name>  <url >http://maven.apache.org</url>     <properties>  < spring.version>4.1.1.release</spring.version>  </properties>     <dependencies>    <dependency>      <groupid >junit</groupid>      <artifactid>junit</artifactid>      <version>3.8.1< /version>      <scope>test</scope>    </ Dependency>        <dependency><groupid> org.springframework</groupid><artifactid>spring-core</artifactid><version>${ spring.version}</version></dependency><dependency><groupid>org.springframework</ Groupid><artifactid>spring-webmvc</artifactid><version>${spring.version}</version> </dependency><dependency><groupId>org.springframework</groupId><artifactId> spring-beans</artifactid><version>${spring.version}</version></dependency>< dependency><groupid>org.springframework</groupid><artifactid>spring-context</ artifactid><version>${spring.version}</version>&Lt;/dependency><dependency><groupid>jstl</groupid><artifactid>jstl</artifactid ><version>1.2</version></dependency><dependency><groupid>taglibs</groupid ><artifactId>standard</artifactId><version>1.1.2</version></dependency>       </dependencies>  <build>    < Finalname>favspringmvcrestful</finalname>  </build></project>

(iv) in Web-inf/web.xml, configure Spring MVC forwarding.

<?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 "><display-name> Favspringmvcrestful</display-name><filter><filter-name>encodingfilter</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>encodingfilter</ filter-name><url-pattern>/*</url-pattern></filter-mapping><listener>< Listener-class>org.springframework.web.context.contextloaderlistener</listener-class></listener><servlet><servlet-name>springmvc</ Servlet-name><servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class> <init-param><param-name>contextconfiglocation</param-name><param-value>classpath*: spring-context.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>

(v) Under the Resources directory, create spring-context.xml, support annotations, page path resolution, and so on.

<?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:mvc=" Http://www.springframework.org/schema/mvc "xsi:schemalocation = "http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/ spring-beans.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/ context/spring-context-4.1.xsdhttp://www.springframework.org/schema/mvc http://www.springframework.org/ Schema/mvc/spring-mvc-4.1.xsd "><context:component-scan base-package=" Com.favccxx.favsoft.favjson.controller "></context:component-scan><mvc:annotation-driven></ Mvc:annotation-driven>    <bean id= "Viewresolver"  class= " Org.springframework.web.servlet.view.UrlBasedViewResolver "&GT;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBSP;&NBsp;<property name= "Viewclass"              Value= "Org.springframework.web.servlet.view.JstlView"  />         <property name= "prefix"  value= "/web-inf/views"  />         <property name= "suffix"  value= ". JSP"  />    </ Bean></beans>

(vi) Create a new Hellocontroller class and use annotations to complete the call of the spring MVC class.

package com.favccxx.favsoft.favjson.controller;import  java.util.hashmap;import java.util.map;import org.springframework.stereotype.controller;import  org.springframework.web.bind.annotation.requestmapping;import  org.springframework.web.bind.annotation.requestparam;import org.springframework.web.servlet.modelandview; @Controllerpublic  class hellocontroller {@RequestMapping ("/greeting")      Public modelandview greeting (@RequestParam (value= "name",  defaultvalue= "World")  string  name)  { system.out.println ("hello "  + name);  map<string, object > map = new HashMap<String, Object> ();  map.put ("UserName",  name);  return new modelandview ("/hello", map);     } } 

(vii) Creation of/WEB-INF/VIEWS/HELLO.JSP for the presentation of data.

<%@ 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>

(eight) in the browser, enter the access URL:HTTP://LOCALHOST:8080/FAVSPRINGMVCRESTFUL/GREETING?NAME=%E7%BE%8E%E5%A5%B3, the operation effect is as follows:
