MyEclipse使用Maven创建web项目+搭建SSM框架教程
博文中的代码：链接：http://pan.baidu.com/s/1o8tqIMI 密码：m3si

安装maven和配置
1、下载maven.apache.org/download.html，下载apache-maven-3.1.1-bin.zip，**-src.zip为Maven的源码
2、配置环境变量，打开系统环境变量新建一个M2_HOME将解压后的Maven存放路径放在此，然后在path路径下加入%M2_HOME%\bin路径
3、检测是否配置成功，打开命令行输入echo %M2_HOME%查看M2_HOME指向的Maven存放安装目录是否正确，输入mvn -v查看是否能找到正确的mvn执行脚本
4、以后升级的话将M2_HOME的路径换为最新的安装目录就行
5、Maven实践：初次安装完后输入mvn help:system的命令，此时会打印出所有的Java系统属性和环境变量，然后Maven会执行一个真正的任务将相应的所需的构件下载到本地仓库中包括pom和jar文件，然后用户在C:\Users\Administrator.m2下就能看到本地仓库了
6、用户需要复制M2_HOME/conf/setting.xml文件到C:/Users/Administrator/.m2/setting.xml，这样用户每次升级后就不要在次修改setting.xml文件了

MyEclipse配置Maven
1、在本地创建一个文件夹MavenRepository，并在MavenRepository文件夹下创建文件夹repo
2、进入Maven解压后的文件夹，进入conf文件夹，将settings.xml文件复制到上一步创建的MavenRepository文件夹下

3、打开MavenRepository文件夹下的settings.xml文件，找到localRepository标签，此时是被注释掉的，我们解除注释，然后配置步骤1中的repo路径，如E:\MavenRepository\repo

4、在MyEclipse中的Perferences进行如下配置，添加自己的Maven

5、User Settings设置为之前修改过的setting.xml

6、File->New->others，搜索maven，如果看到有Maven Project则代表配置成功

MyEclipse使用maven创建web项目
1、创建一个maven项目

2、按照上面教程，即可创建出一个Maven项目，项目结构如下图

3、将JRE版本设置为1.7，可使用默认的或者自己导入

4、此时index.jsp会报以下错误

在pom.xml文件的dependencies节点下添加如下代码即可，添加完后，会下载对应的jar包

5、右键项目，选择Properties，进行如下配置

搭建Spring+SpringMVC+Mybatis框架

1、Maven引入项目用到的jar包，修改pom.xml后保存会自动下载，存放在之前配置的本地仓库中，即：
E:\MavenRepository\repo文件夹

pom.xml

2、在src/main/resources下添加如下配置文件

applicationContext.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-3.1.xsd  http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context-3.1.xsd  http://www.springframework.org/schema/mvc  http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd"><!-- 使用注解式注入 --><context:annotation-config /><!-- 自动扫描 --><context:component-scan base-package="com.chillax" /><!-- 导入DAO配置 --><import resource="spring-dao.xml"/><!-- 导入数据库配置 --><import resource="spring-db.xml"/><!-- 导入数据库配置 --><import resource="spring-tx.xml"/></beans>

jdbc.properties

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://127.0.0.1:3306/maventest
username=root
password=root
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

log4j.properties

#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB

输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志

log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH:mm:ss}][%c]%m%n

4、在src/main/java下添加如下包和类

UserController.java

package com.chillax.controller;import java.util.List;import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;import com.chillax.dto.User;
import com.chillax.service.IUserService;@Controller
@RequestMapping("/user")
public class UserController {@Resourceprivate IUserService userService;@RequestMapping("/userList")public String userList(HttpServletRequest request,Model model){List<User> uList = userService.getAllUser();model.addAttribute("uList", uList);return "userList";}@RequestMapping("/showUser")public String showUser(HttpServletRequest request,Model model){int userId = Integer.parseInt(request.getParameter("id"));User user = userService.getUserById(userId);model.addAttribute("user", user);return "showUser";}@RequestMapping("/addUserUI")public String addUserUI(){return "addUser";}@RequestMapping("/addUser")public String addUser(HttpServletRequest request,Model model){User user = new User();user.setName(String.valueOf(request.getParameter("name")));user.setPassword(String.valueOf(request.getParameter("password")));user.setAge(Integer.parseInt(String.valueOf(request.getParameter("age"))));userService.addUser(user);return "redirect:/user/userList";}
}

IUserDao.java

package com.chillax.dao;import java.util.List;
import java.util.Map;import com.chillax.dto.User;public interface IUserDao {public User queryByPrimaryKey(Integer id);public List<User> queryUserByBatch(Map<String,Object> params);public void insertUser(User user);public void insertUserByBatch(List<User> list);public void deleteByPrimaryKey(Integer id);public void delteUserByBatch(Map<String,Object> params);public void updateByPrimaryKey(Integer id);public List<User> getAllUser();}

User.java

package com.chillax.dto;public class User {private Integer id;private String name;private String password;private Integer age;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password == null ? null : password.trim();}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}
}

UserMapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >

IUserService.java

package com.chillax.service;import java.util.List;import com.chillax.dto.User;public interface IUserService {public User getUserById(int userId);public void insertUser(User user);public void addUser(User user);public List<User> getAllUser();
}

UserServiceImpl.java

package com.chillax.service.Impl;import java.util.List;import javax.annotation.Resource;import org.springframework.stereotype.Service;import com.chillax.dao.IUserDao;
import com.chillax.dto.User;
import com.chillax.service.IUserService;@Service("userService")
public class UserServiceImpl implements IUserService {@Resourceprivate IUserDao userDao;public User getUserById(int userId) {return userDao.queryByPrimaryKey(userId);}public void insertUser(User user) {userDao.insertUser(user);}public void addUser(User user) {userDao.insertUser(user);}@Overridepublic List<User> getAllUser() {return userDao.getAllUser();}}

5、在WEB-INF文件夹下创建jsp文件夹，并添加userList.jsp、addUser.jsp、showUser.jsp userList.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html><head><base href="<%=basePath%>"><title>My JSP 'showUser.jsp' starting page</title><meta http-equiv="pragma" content="no-cache"><meta http-equiv="cache-control" content="no-cache"><meta http-equiv="expires" content="0">    <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"><meta http-equiv="description" content="This is my page"><!--<link rel="stylesheet" type="text/css" href="styles.css">--></head><body><c:forEach items="${uList }" var="u">用户名称：${u.name}用户年龄：${u.age }<br/></c:forEach></body>
</html>

addUser.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
