SpringMvc初级篇(一)

SpringMvc初级篇(一)

目标：使用SpringMvc框架，开发HelloWorld项目

步骤：
1.准备SpringMvc相关jar包
commons-io-1.2.jar
commons-logging-1.1.1.jar
freemarker.jar
hibernate-validator-4.0.2.GA.jar
jstl-1.2.jar
log4j-1.2.14.jar
org.springframework.context.support-3.1.0.M2.jar
servlet-2.3.jar
slf4j-api-1.5.6.jar
slf4j-log4j12-1.5.6.jar
spring-asm-3.0.3.RELEASE.jar
spring-beans-3.0.3.RELEASE.jar
spring-context-3.0.3.RELEASE.jar
spring-core-3.0.3.RELEASE.jar
spring-expression-3.0.3.RELEASE.jar
spring-web-3.0.3.RELEASE.jar
spring-webmvc-3.0.3.RELEASE.jar
validation-api-1.0.0.GA.jar
commons-fileupload-1.1.1.jar

2.创建Dynamic Web Project项目,名称为helloworld,将SpringMvc相关jar包复制到WEB-INF/lib文件夹下

3.配置SpringMvc相关文件

①web.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" xmlns:web ="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation ="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id ="WebApp_ID" version ="3.0" >
< display-name >helloworld </ display-name >
< servlet >
< servlet-name >dispatcher </ servlet-name >
< servlet-class >org.springframework.web.servlet.DispatcherServlet </ servlet-class >
< load-on-startup >1 </ load-on-startup >
</ servlet >
< servlet-mapping >
< servlet-name >dispatcher </ servlet-name >
< url-pattern >*.html </ url-pattern >
</ servlet-mapping >
< welcome-file-list >
< welcome-file >index.html </ welcome-file >
< welcome-file >index.htm </ welcome-file >
< welcome-file >index.jsp </ welcome-file >
< welcome-file >default.html </ welcome-file >
< welcome-file >default.htm </ welcome-file >
< welcome-file >default.jsp </ welcome-file >
</ welcome-file-list >
</ web-app >

②在WEB-INF文件夹下新建dispatcher-servlet.xml：

<? 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:p ="http://www.springframework.org/schema/p"
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-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
" >

<!-- 搜索的控制类路径(C) -->
< context:component-scan base-package ="com.myapps.controllers" />

<!-- 配置视图路径(V) -->
< bean id ="viewResolver" class ="org.springframework.web.servlet.view.InternalResourceViewResolver" >
< property name ="prefix" value ="/WEB-INF/views/" />
< property name ="suffix" value =".jsp" />
</ bean >
</ beans >

③新建包：com.myapps.controllers

④在上面的包内新建类：HelloWorldController.java

package com.myapps.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class HelloWorldController {

@RequestMapping(value="/helloworld")
public ModelAndView helloWord() {
return new ModelAndView("helloworldPage", "name", "hdh");
}
}

⑤在WEB-INF文件夹下新建views文件夹，在views文件夹内新建helloworldPage.jsp

<% @ 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 >helloworldPage.jsp </ title >
</ head >
< body >
Hello,world.Welcome ${name} here.
</ body >
</ html >

⑥接着在WebContent下新建index.htm(注意后缀是htm,因为如果是html的话，会和web.xml的<url-pattern>*.html</url-pattern>拦截的后缀名冲突，当然也可以新建index.jsp文件)

<! 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 >index.htm </ title >
</ head >
< body >
< a href ="helloworld.html" >hello,world(htm) </ a >
</ body >
</ html >

⑦最后，部署项目，然后启动tomcat服务器，输入http://localhost:8080/helloworld/index.htm ,点击链接进行测试。这样简单的Hello,world入门就完成了。
