基于MyEclipse的maven+springMVC项目创建

1、基于MyEclipse的maven+springMVC项目创建及测试一准备工作：安装MyEclipse10（已经集成了maven工具）二项目建立步骤1.File->New->Other出现如下对话框选择Maven Project项目，Next默认不变，Next选择如上图，NextGroup Id和Artifact Id自定义，Package可写可不写，项目完成可再加。Finish完成。项目目录如图：2.完善项目首先，完善目录，增加重要的source Folder，这个不是简单的Floder,这些文件夹是会参与编译的。增加src/main/java，src/test/resource

2、s，src/test/java目录。让目录变成标准的maven结构。右击项目->Bulid Path->New Source Folder,如下图：Finish完成3. 配置Maven工程 右击项目->Properties->Resource,让项目的字符集为UTF-8，如图3.将工程变为Web工程选择Dynamic Web Module,版本选择3.0，如图：要配置web项目的发布目录，就是Deployment Assembly，如图：test目录不要发布，所以删掉以上两项。并且增加src/main/webapp目录，和Maven Dependenices,完成之后如

3、下图：4. 赋予工程的springmvc特性（添加配置文件）项目的配置文件目录如下图：(1) .配置web.xml，使其具有springmvc特性，主要配置两处，一个是ContextLoaderListener，一个是DispatcherServlet。代码如下：web.xml<?xml version="1.0" encoding="UTF-8"?><web-app version="2.4" xmlns=" xmlns:xsi="/2001/XMLSchema-

4、instance" xsi:schemaLocation=" <listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><servlet><servlet-name>exam</servlet-name><servlet-class>org.springframework.web.servlet.DispatcherServl

6、extLoaderListener表示，该工程要以spring的方式启动。启动时会默认在/WEB-INF目录下查找applicationContext.xml作为spring容器的配置文件，这里可以初始化一些bean，如DataSource。我们这里什么也不做。代码如下：applicationContext.xml<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE beans PUBLIC "-/SPRING/DTD BEAN/EN""http:/www.spri

7、/dtd/spring-beans.dtd"><beans></beans>(3) .配置DispatcherServlet表示，该工程将采用springmvc的方式。启动时也会默认在/WEB-INF目录下查找XXX-servlet.xml作为配置文件，XXX就是DispatcherServlet的名字，该文件中将配置两项重要的mvc特性：HandlerMapping,负责为DispatcherServlet这个前端控制器的请求查找Controller；ViewResolver,负责为DispatcherServlet查找M

18、/build></project>6. 测试文件目录如下图：(1) .先写Controller。编写两个类，LoginControler.java，LoginForm.java。代码如下LoginController.javapackage cc.monggo.web.controller;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.stereotype.Controller;impor

19、t org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.servlet.ModelAndView;import cc.monggo.domain.LoginForm;Controllerpublic class LoginController RequestMapping(value="login") public ModelAndView login(HttpServletRequest request,HttpServletResponse respo

20、nse,LoginForm command ) String username = command.getUsername(); ModelAndView mv = new ModelAndView("/index/index","command","LOGIN SUCCESS, " + username); return mv; LoginForm.javapackage cc.monggo.domain; public class LoginForm private String username; private String

21、password; public String getUsername() return username; public void setUsername(String username) this.username = username; public String getPassword() return password; public void setPassword(String password) this.password = password; (2).再增加一些jsp,首页的index.jsp,主要是做跳转，代码如下：<% request.getRequestDisp

22、atcher("/WEB-INF/jsp/login/login.jsp").forward(request,response); %>(3) .还有两个jsp，做些简单的功能，一个表单login.jsp,一个表单提交的返回index.jsp，代码如下：login.jsp<% page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%><!DOCTYPE html PUBLIC "
