springMVC+mybatis框架搭建
　　在上一遍博客中以及讲诉了新建maven项目的流程，现在紧跟上一遍文章，接着搭建spring项目
　　首先我们先要弄清搭建项目的一般流程，需要注意哪些方面，想要什么样的效果，自己的功能有哪些？
　　（假设效果：项目目录结构清晰，能够查询到本地数据库中的内容。。）
1.  工程目录结构整理清楚
　　在src/main/java文件夹中，新建包cn.springmvc.model(存放javabean),
　　cn.springmvc.dao（存放spring与mybatis连接接口）,
　　cn.springmvc.service（service接口）,
　　cn.springmvc.service.impl（service接口的实现），
　　cn.springmvc.controller（存放控制层controller）
　　在src/main/resource文件夹中，新建包conf（存放配置文件），
　　mapper（mybatis的mapper文件）
　　在src/test/java文件夹中，新建包cn.springmvc.test(存放测试文件)
　　在WEB-INF文件夹下新建jsp文件夹（存放jsp文件）
　　这样项目结构基本完成了
2.  引入依赖包
　　打开maven的pom文件，对本次开发所需使用的架包依次导入（maven项目管理的优势）
　　查找依赖结构有个不错的网站，http://search.maven.org/   只要输入包名即可查找引来关系
　　pom.xml(包依赖)

　　conf/ jdbc.properties（jdbc配置文件)
?1234jdbc_driverClassName=com.mysql.jdbc.Driverjdbc_url=jdbc:mysql://localhost:3306/mydays?useUnicode=true&amp;characterEncoding=utf-8jdbc_username=rootjdbc_password=root4.  配置spring配置文件
　　conf/spring.xml(spring配置文件的扫描)

　　cn.springmvc.model/User.java(用户基本信息)
?123456789101112131415161718192021222324252627282930package cn.springmvc.model;  /** * 用户表 */public class User {     private int id;    private int state;    private String nickname;    public int getId() {        return id;    }    public void setId(int id) {        this.id =>    }    public int getState() {        return state;    }    public void setState(int state) {        this.state = state;    }    public String getNickname() {        return nickname;    }    public void setNickname(String nickname) {        this.nickname = nickname;    }}cn.springmvc.dao/UserDAO.java(dao操作接口)?12345678910111213141516package cn.springmvc.dao; import cn.springmvc.model.User;  public interface UserDAO {     /**     * 添加新用户     * @param user     * @return     */    public int insertUser(User user);          }　　cn.springmvc.service/UserService.java(service层接口)
?123456789package cn.springmvc.service; import cn.springmvc.model.User;  public interface UserService {     public int insertUser(User user);}cn.springmvc.service.impl/UserServiceImpl.java(service层接口实现)?1234567891011121314151617181920212223package cn.springmvc.service.impl; import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service; import cn.springmvc.dao.UserDAO;import cn.springmvc.model.User;import cn.springmvc.service.UserService;  @Servicepublic class UserServiceImpl implements UserService{     @Autowired    private UserDAO userDAO;         @Override    public int insertUser(User user) {        // TODO Auto-generated method stub        return userDAO.insertUser(user);    } }6.  mybatis配置
　　conf/mybatis-config.xml(mybatis配置的基本文件)
?1234567891011121314<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>        <!-- 命名空间 -->    <typeAliases>         <typeAlias alias="User" type="cn.springmvc.model.User"/>     </typeAliases>     <!-- 映射map -->    <mappers>    </mappers></configuration>mapper/UserMapper.xml(mybatis的实现)?1234567891011121314151617<?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"><mapper namespace="cn.springmvc.dao.UserDAO">                     <insert id="insertUser" parameterType="User" keyProperty="id">             insert into days_user(           state,         nickname)          values          (                 #{state},         #{nickname})         </insert>          </mapper>这样就完成了基本插入用户的功能！7.  junit测试插入功能
　　cn.springmvc.test/UserTest.java(用户测试模块)
?1234567891011121314151617181920212223242526272829303132package cn.springmvc.test; import org.junit.Before;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext; import cn.springmvc.model.User;import cn.springmvc.service.UserService;   public class UserTest { private UserService userService;         @Before    public void before(){                                                                            @SuppressWarnings("resource")        ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"classpath:conf/spring.xml"                ,"classpath:conf/spring-mybatis.xml"});        userService = (UserService) context.getBean("userServiceImpl");    }         @Test    public void addUser(){        User user = new User();        user.setNickname("你好");        user.setState(2);        System.out.println(userService.insertUser(user));    }}测试结果如图：

　　即完成插入功能！
