Maven(3)：新建Java WebProject

1.建成后的整体目录

2. 新建maven project

右键new -> other project -> 输入搜索maven project -> 勾选create a simple project -> Next ->填写Group Id 和Artifact Id，选择war包 ->Finish

3.修改Dynamic Web Module为3.0

项目右键properties -> 搜索project facets -> 修改 Dynamic Web Module 为3.0

直接点击修改无法保存，修改.settings 下的org.eclipse.wst.common.project.facet.core.xml 文件中的 <installed facet="jst.web" version="2.5"/> 修改版本为3.0

4.修改输出目录以及导出文件夹和顺序

(1)修改输出目录

MyEclipse 项目工程右键Bulid Path -> Configure Bulid Path 如下图修改输出目录

(2)修改导出文件夹顺序

5.检查统一JDK版本

以下三个地方的jdk版本需统一、一致。

6.sping+mybatis配置

(1)建成后的基本目录

(2)POM文件

pom.xml提供项目所需的jar包。

配置controller(UserController.java)

package com.now.controller;import javax.annotation.Resource;  import org.springframework.stereotype.Controller;  import org.springframework.web.bind.annotation.RequestMapping;  import org.springframework.web.servlet.ModelAndView;  import com.now.domain.User;import com.now.service.UserService;  /**  * 功能概要：UserController  */  @Controller  public class UserController {      @Resource      private UserService userService;      @RequestMapping("/")        public ModelAndView getIndex(){              ModelAndView mav = new ModelAndView("index");           User user = userService.selectUserById(1);          mav.addObject("user", user);           return mav;        }    }
