如何搭建springMVC开发环境

Question

如题所述

Answer 1

（一）工作环境准备：
        JDK 1.7
        Eclipse Kepler
        Apache Tomcat 8.0
（二）在Eclipse中新建Maven工程，在Archetype类型中，选择“maven-archetype-webapp”。
（三）配置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>  
    </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> 
（四）在WEB-INF/web.xml，配置Spring MVC转发。
    <?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>  
（五）在resources目录下，创建spring-context.xml，支持注解，页面路径解析等。
    <?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.xsd  
            http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd  
            http://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">  
            <property name="viewClass"  
                value="org.springframework.web.servlet.view.JstlView" />  
            <property name="prefix" value="/WEB-INF/views" />  
            <property name="suffix" value=".jsp" />  
        </bean>  
    </beans>  
（六）新建HelloController类，使用注解完成Spring MVC类的调用。
    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;  
    @Controller  
    public 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);  
        }  
    }  
（七）创建/WEB-INF/views/hello.jsp，用来展现数据。
    <%@ 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>  
    <html>  
    <head>  
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">  
    <title>Hello</title>  
    </head>  
    <body>  
        ä½ å¥½ï¼Œ${userName }  
    </body>  
    </html>
