寄語：本文采用IDEA開發(fā)，建議按著文章順序先搭建項(xiàng)目，只要按著目錄結(jié)構(gòu)先把目錄建好就是復(fù)制粘貼的問題投蝉。內(nèi)里代碼也有注釋锤灿，先搭建好，在慢慢看著代碼思考斯够，想想問什么這么做？即使你是初學(xué)者，按著一步一步也是可以搭建整合的翻默。

1. 創(chuàng)建maven項(xiàng)目

1.1 File -> New Module，進(jìn)入創(chuàng)建項(xiàng)目窗口恰起。

1.2 點(diǎn)擊Next修械，填寫GroupId、ArtifactId和Version

1.3 接著下一步检盼，這里需要注在Properties中添加一個(gè)參數(shù)archetypeCatalog=internal

1.4 填寫Module name

創(chuàng)建完成

生成項(xiàng)目骨架：Maven在自動(dòng)下載所需要的jar包,以下代碼段可以選擇跳過肯污，為控制臺(tái)輸出Maven的log

1.6 Maven骨架搭建之后，個(gè)人建議可以先按著以下目錄圖把項(xiàng)目所有需要的文件準(zhǔn)備好吨枉，繼續(xù)看下去就是把代碼復(fù)制到各個(gè)文件蹦渣，非常簡(jiǎn)單方便。

3.做一個(gè)查詢小demo

3.1Controller文件 UserController

package com.ninth.ssm.controller;

import com.ninth.ssm.model.User;
import com.ninth.ssm.service.UserService;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest;
import java.util.List;

/**
 * Created by Ninth on 2017-10-28 15:29.
 * 
**/


@Controller
@RequestMapping("/user")
public class UserController {

    private Logger log = Logger.getLogger(UserController.class);
    @Resource
    private UserService userService;

    @RequestMapping("/showUser")
    public String showUser(HttpServletRequest request, Model model){
        log.info("查詢所有用戶信息");
        List<User> userList = userService.getAllUser();
        model.addAttribute("userList",userList);
        return "showUser";
    }
}

3.2 dao文件 UserDao

package com.ninth.ssm.dao;

import com.ninth.ssm.model.User;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;

import java.util.List;

/**
 * Created by Ninth on 2017-10-28 15:29.
 * 
**/


@Repository
public interface UserDao {

    User selectUserById(@Param("userId") Long userId);

    User selectUserByPhoneOrEmail(@Param("emailOrPhone") String emailOrPhone, @Param("state") Short state);

    List<User> selectAllUser();
}

3.3 model文件 User

package com.ninth.ssm.model;

import java.util.Date;

/**
 * Created by Ninth on 2017-10-28 15:29.
 *
**/

public class User {

    private Long id;
    private String userName;
    private String userPhone;
    private String userEmail;
    private String userPwd;
    private String pwdSalt;
    private Date createTime;
    private Date modifyTime;
    private Short isDelete;

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public String getUserPhone() {
        return userPhone;
    }

    public void setUserPhone(String userPhone) {
        this.userPhone = userPhone;
    }

    public String getUserEmail() {
        return userEmail;
    }

    public void setUserEmail(String userEmail) {
        this.userEmail = userEmail;
    }

    public String getUserPwd() {
        return userPwd;
    }

    public void setUserPwd(String userPwd) {
        this.userPwd = userPwd;
    }

    public String getPwdSalt() {
        return pwdSalt;
    }

    public void setPwdSalt(String pwdSalt) {
        this.pwdSalt = pwdSalt;
    }

    public Date getCreateTime() {
        return createTime;
    }

    public void setCreateTime(Date createTime) {
        this.createTime = createTime;
    }

    public Date getModifyTime() {
        return modifyTime;
    }

    public void setModifyTime(Date modifyTime) {
        this.modifyTime = modifyTime;
    }

    public Short getIsDelete() {
        return isDelete;
    }

    public void setIsDelete(Short isDelete) {
        this.isDelete = isDelete;
    }
}

3.3.1數(shù)據(jù)庫文件

在sql創(chuàng)建數(shù)據(jù)庫db_ssm,然后運(yùn)行目錄下的sql文件，自動(dòng)生成表堪滨，當(dāng)然胯陋，你也可以手動(dòng)建表。

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------
-- Table structure for `t_user`
-- ----------------------------
DROP TABLE IF EXISTS `t_user`;
CREATE TABLE `t_user` (
  `id` bigint(11) NOT NULL auto_increment,

3.4 Service文件 UserService

package com.ninth.ssm.service;

import com.ninth.ssm.model.User;
import java.util.List;

/**
 * Created by Ninth on 2017-10-28 15:30.
 * 
**/

public interface UserService {

    List<User> getAllUser();

    User getUserByPhoneOrEmail(String emailOrPhone, Short state);

    User getUserById(Long userId);
}

3.4.1 Service實(shí)現(xiàn)類 IUserServiceimpl

package com.ninth.ssm.service.impl;

import com.ninth.ssm.dao.UserDao;
import com.ninth.ssm.model.User;
import com.ninth.ssm.service.UserService;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import javax.annotation.Resource;
import java.util.List;

/**

@Service
@Transactional(rollbackFor = Exception.class)
public class UserServiceImpl implements UserService {

    @Resource
    private UserDao userDao;

    public User getUserById(Long userId) {
        return userDao.selectUserById(userId);
    }

    public User getUserByPhoneOrEmail(String emailOrPhone, Short state) {
        return userDao.selectUserByPhoneOrEmail(emailOrPhone,state);
    }

    public List<User> getAllUser() {
        return userDao.selectAllUser();
    }
}

3.5 Mapper文件 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" >

4.項(xiàng)目部署

4.1 識(shí)別目錄作用，選擇File-Project Structure

4.3 創(chuàng)建一個(gè)Tomcat容器實(shí)例发笔，并把項(xiàng)目部署進(jìn)去

4.4 項(xiàng)目所需配置好項(xiàng)目訪問的根路徑盟萨，然后啟動(dòng)Tomcat。

4.5 瀏覽器訪問驗(yàn)證 瀏覽器輸入http://localhost:8080/maver-ssm/user/showUser了讨，出現(xiàn)下圖捻激，恭喜你
