SpringMvc&Maven初级篇(一)

SpringMvc&Maven初级篇(一)

开发工具：Eclipse IDE for Java EE Developers
目标：使用SpringMvc框架和Maven配置，开发HelloWorld项目
步骤：
1.新建--Maven Project



2.配置eclipse:
右键项目，选择Project Facets，点击Convert to faceted from

更改Dynamic Web Module的Version为2.5。(3.0为Java7的)。如果提示错误，可能需要在Java Compiler设置Compiler compliance level 为1.6。或者需要在此窗口的Java的Version改成1.6。

点击Further configuration available…，弹出Modify Faceted Project窗口此处是设置web.xml文件的路径，我们输入src/main/webapp。Generate web.xml deployment descriptor自动生成web.xml文件，推荐勾选。
设置部署程序集(Web Deployment Assembly)：

 Add -> Java Build Path Entries -> Maven Dependencies -> Finish

设置完成效果图

3.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/xsd/maven-4.0.0.xsd" >

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"  xmlns:web ="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

     < 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 >

         < welcome-file > default.htm </ welcome-file >
         < welcome-file > default.jsp </ welcome-file >
     </ welcome-file-list >
</ web-app >

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/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 >

在WEB-INF下新建文件夹：views
在views文件夹下新建

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 >

新建包：com.myapps.controllers

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");

}
}

 

接着在webapp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 >

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。
