IDEA2017 SSM框架整合搭建 Maven + Sprin

作者: _Ninth | 来源:发表于2017-10-28 16:39 被阅读288次

    寄语：本文采用IDEA开发，建议按着文章顺序先搭建项目，只要按着目录结构先把目录建好就是复制粘贴的问题。内里代码也有注释，先搭建好，在慢慢看着代码思考，想想问什么这么做？即使你是初学者，按着一步一步也是可以搭建整合的。

    步骤目录
    1.创建Maven项目
    1.1-1.6 看图操作
    2.配置文件
    2.1pom.xml
    2.2jdbc.properties
    2.3log4j.properties
    2.4spring-mvc.xml
    2.5spring-mybatis.xml
    2.6web.xml
    3.创建demo
    3.1Controller
    3.2 Dao
    3.3 model
    3.3.1数据库文件
    3.4 Service
    3.4.1 ServiceImpl
    4.项目部署
    4.1 识别目录
    4.3 创建一个Tomca
    4.4 配置访问根路径
    4.5 浏览器访问

    1. 创建maven项目

    1.1 File -> New Module，进入创建项目窗口。

    1.2 点击Next，填写GroupId、ArtifactId和Version

    1.3 接着下一步，这里需要注在Properties中添加一个参数archetypeCatalog=internal

    1.4 填写Module name

    创建完成


    生成项目骨架：Maven在自动下载所需要的jar包,以下代码段可以选择跳过，为控制台输出Maven的log

    1.6 Maven骨架搭建之后，个人建议可以先按着以下目录图把项目所有需要的文件准备好，继续看下去就是把代码复制到各个文件，非常简单方便。

    3.做一个查询小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("查询所有用户信息");
        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数据库文件

    在sql创建数据库db_ssm,然后运行目录下的sql文件，自动生成表，当然，你也可以手动建表。

    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,
  `user_name` varchar(255) default NULL COMMENT '用户名',
  `user_phone` varchar(20) default NULL COMMENT '手机号',
  `user_email` varchar(255) default NULL COMMENT '邮箱地址',
  `user_pwd` varchar(32) default NULL COMMENT '加盐后用户密码',
  `pwd_salt` varchar(6) default NULL COMMENT 'MD5盐',
  `create_time` datetime default NULL COMMENT '创建时间',
  `modify_time` datetime default NULL COMMENT '最后修改时间',
  `is_delete` tinyint(4) default NULL COMMENT '是否删除，0-未删除；1-已删除',
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8 COMMENT='用户登录表';

-- ----------------------------
-- Records of t_user
-- ----------------------------
INSERT INTO `t_user` VALUES ('1', '赵大宝', '13285250574', '1045221654@qq.com', '05126a423a9379d529e4ee61a212fa55', 'KJUYT5', '2016-07-15 23:38:56', '2016-07-15 23:39:09', '0');
INSERT INTO `t_user` VALUES ('2', '张三丰', '15985250574', '1198224554@qq.com', '98bd3a1bebde01ad363d3c5a0d1e56da', '656JHU', '2016-07-15 23:39:01', '2016-07-15 23:39:13', '0');
INSERT INTO `t_user` VALUES ('3', '王尼玛', '13685250574', '1256221654@qq.com', '5470db9b63c354f6c8d628b80ae2f3c3', '89UIKQ', '2016-07-15 23:39:05', '2016-07-15 23:39:16', '0');

    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实现类 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;

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


@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" >
<mapper namespace="com.ninth.ssm.dao.UserDao">

    <resultMap id="UserBaseMap" type="com.ninth.ssm.model.User">
        <id column="id" property="id" jdbcType="BIGINT"/>
        <result column="user_name" property="userName" jdbcType="VARCHAR"/>
        <result column="user_phone" property="userPhone" jdbcType="VARCHAR"/>

        <result column="modify_time" property="modifyTime" jdbcType="DATE"/>
        <result column="is_delete" property="isDelete" jdbcType="SMALLINT"></result>
    </resultMap>

    <select id="selectUserById" parameterType="java.lang.Long" resultMap="UserBaseMap">
        SELECT * FROM t_user
        WHERE id = #{userId}
    </select>

    <select id="selectUserByPhoneOrEmail" resultMap="UserBaseMap">
        SELECT * FROM t_user
        WHERE user_email = #{emailOrPhone} OR user_phone = #{emailOrPhone}
        AND user_state = #{state}
    </select>

    <select id="selectAllUser" resultMap="UserBaseMap">
        SELECT * FROM t_user
    </select>

</mapper>

    4.项目部署

    4.1 识别目录作用，选择File-Project Structure

    4.3 创建一个Tomcat容器实例，并把项目部署进去

    4.4 项目所需配置好项目访问的根路径，然后启动Tomcat。

    4.5 浏览器访问验证 浏览器输入http://localhost:8080/maver-ssm/user/showUser，出现下图，恭喜你
