ssm基础搭建步骤

　　　　今天搭建新的项目环境，从网上找了些ssm的搭建步骤，终于找到了一位csdn的大佬，可以说写的特别详细，按照上面步骤搭建即可，为了方便日后参考，转载到本人博客，原文链接：https://blog.csdn.net/khxu666/article/details/79851070；

　　这篇文章主要以idea做参考，没有的自己破解，其余的工具可以根据下面步骤下载安装和使用

开发工具

IntelliJ IDEA Ultimate 2017.2.2
Apache-tomcat-9.0.5
JDK 1.8.0_121
MySQL 5.7
Maven 3.3.9

工程结构

最终完成后的工程结构：

下面开始详细的讲解项目的开发过程。

IDEA+Maven搭建项目骨架
1. 新建Maven项目：
点击File -> New -> Project -> Maven -> 勾选 Create from archetype -> 选择 maven-archetype-webapp (注意：此处不要错选成上面的cocoom-22-archetype-webapp)

在弹出的new project 选项卡中填写GroupId和Artifactid，其中GroupID是项目组织唯一的标识符，实际对应JAVA的包的结构，是main目录里java的目录结构，ArtifactID是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。对于入门练习，这两项可以随意填写。

之后点击next 选择Maven版本（其中IDEA 专业版自带Maven，也可以选择自己下载的maven）。之后填写项目名称和项目地址，完成后点击Finish，完成项目骨架的创建。

2. 在新建的项目中添加所需要的文件/文件夹

创建之后的项目如图所示，我们需要在这之上新建一些目录。

在项目的根目录下新建target文件夹，系统自动将其设置为“Excluded”

在src/main目录下新建Directory：“java”，并将其设置为“Source Root”（即：此项目默认的代码文件源目录）

在刚才新建的java文件下新建“com”包，再在com包下新建四个包，分别命名为：pojo,service,dao,controller。（如果出现下图中所示的包名重叠的情况，可以点击图中所示的图标，将“Hide empty middle package取消掉”）

上面新建的四个包：pojo,service,dao,controller，其所存放的分别是：

pojo: 存放自定义的java类。如：paper类，user类，book类等，每个类的属性设为private，并提供public属性的getter/setter方法让外界访问
service：定义接口，包含系统所提供的功能。（之后还会在service包下再新建impl包）。
dao：定义接口，包含与数据库进行交互的功能。
controller：控制器，负责接收页面请求，转发和处理。
在resource包下新建Directory：“mapper”（用于存放xxxMapper.xml文件）和“spring”（用于存放spring-xxx.xml配置文件），新建文件：“jdbc.properties”（mysql数据库配置文件）,”log4j.properties”（日志输出配置文件）,”mybatis-config.xml”（mybatis框架配置文件）。

在web-inf目录下新建“jsp”包，存放xxx.jsp显示界面。
补充之后的项目目录如下图所示，至此项目骨架搭建完毕，开始写代码实现增删改查功能。

3. 自定义Paper类

在这之前要对项目的pom.xml文件进行配置，在此文件中配置项目所需要的jar包。

pom.xml

本项目所用的数据库为MySQL 5.7 建表语句如下：

SET FOREIGN_KEY_CHECKS=0;

-- ----------------------------

-- Table structure for `paper`

-- ----------------------------

DROP TABLE IF EXISTS `paper`;

CREATE TABLE `paper` (

  `paper_id` bigint(20) NOT NULL AUTO_INCREMENT COMMENT 'paperID',

  `name` varchar(100) NOT NULL COMMENT 'paper名称',

  `number` int(11) NOT NULL COMMENT 'paper数量',

  `detail` varchar(200) NOT NULL COMMENT 'paper描述',

  PRIMARY KEY (`paper_id`)

) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8 COMMENT='paper表';

-- ----------------------------

-- Records of paper

-- ----------------------------

INSERT INTO `paper` VALUES ('1', '机器学习', '2', 'mlmlmlml');

INSERT INTO `paper` VALUES ('2', '深度学习', '3', 'dldldl');

INSERT INTO `paper` VALUES ('3', '大数据', '4', 'bdbdbd');

下面开始写java代码：

在pojo包中新建Paper.java

package com.pojo;

public class Paper {

    private long paperId;

    private String paperName;

    private int paperNum;

    private String paperDetail;

    public long getPaperId() {

        return paperId;

    }

    public void setPaperId(long paperId) {

        this.paperId = paperId;

    }

    public String getPaperName() {

        return paperName;

    }

    public void setPaperName(String paperName) {

        this.paperName = paperName;

    }

    public int getPaperNum() {

        return paperNum;

    }

    public void setPaperNum(int paperNum) {

        this.paperNum = paperNum;

    }

    public String getPaperDetail() {

        return paperDetail;

    }

    public void setPaperDetail(String paperDetail) {

        this.paperDetail = paperDetail;

    }

}

其中getter/setter方法可以在定义完私有属性之后使用IDEA提供的快捷键：ALT+Insert 来实现快速添加

在service包中新建接口 PaperService：

package com.service;

import com.pojo.Paper;

import java.util.List;

public interface PaperService {

    int addPaper(Paper paper);

    int deletePaperById(long id);

    int updatePaper(Paper paper);

    Paper queryById(long id);

    List<Paper> queryAllPaper();

}

在service包下新建impl包，并在此包中新建PaperServiceImpl.java

package com.service.impl;

import com.pojo.Paper;

import com.dao.PaperDao;

import com.service.PaperService;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import java.util.List;

@Service

public class PaperServiceImpl implements PaperService {

    @Autowired

    private PaperDao paperDao;

    @Override

    public int addPaper(Paper paper) {

        return paperDao.addPaper(paper);

    }

    @Override

    public int deletePaperById(long id) {

        return paperDao.deletePaperById(id);

    }

    @Override

    public int updatePaper(Paper paper) {

        return paperDao.updatePaper(paper);

    }

    @Override

    public Paper queryById(long id) {

        return paperDao.queryById(id);

    }

    @Override

    public List<Paper> queryAllPaper() {

        return paperDao.queryAllPaper();

    }

}

在dao包中新建接口 PaperDao.java

package com.dao;

import com.pojo.Paper;

import java.util.List;

public interface PaperDao {

    int addPaper(Paper paper);

    int deletePaperById(long id);

    int updatePaper(Paper paper);

    Paper queryById(long id);

    List<Paper> queryAllPaper();

}

在controller包中新建 PaperController.java

package com.controller;

import com.pojo.Paper;

import com.service.PaperService;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestMapping;

@Controller

@RequestMapping("/paper")

public class PaperController {

    @Autowired

    private PaperService paperService;

    @RequestMapping("/allPaper")

    public String list(Model model) {

        List<Paper> list = paperService.queryAllPaper();

        model.addAttribute("list", list);

        return "allPaper";

    }

    @RequestMapping("toAddPaper")

    public String toAddPaper() {

        return "addPaper";

    }

    @RequestMapping("/addPaper")

    public String addPaper(Paper paper) {

        paperService.addPaper(paper);

        return "redirect:/paper/allPaper";

    }

    @RequestMapping("/del/{paperId}")

    public String deletePaper(@PathVariable("paperId") Long id) {

        paperService.deletePaperById(id);

        return "redirect:/paper/allPaper";

    }

    @RequestMapping("toUpdatePaper")

    public String toUpdatePaper(Model model, Long id) {

        model.addAttribute("paper", paperService.queryById(id));

        return "updatePaper";

    }

    @RequestMapping("/updatePaper")

    public String updatePaper(Model model, Paper paper) {

        paperService.updatePaper(paper);

        paper = paperService.queryById(paper.getPaperId());

        model.addAttribute("paper", paper);

        return "redirect:/paper/allPaper";

    }

}

在resource/mapper包下新建 PaperMapper.xml（mybatis框架mapper代理开发配置文件）

<?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.dao.PaperDao">

    <resultMap type="Paper" id="paperResultMap" >

        <id property="paperId" column="paper_id"/>

        <result property="paperName" column="name"/>

        <result property="paperNum" column="number"/>

        <result property="paperDetail" column="detail"/>

    </resultMap>

    <insert id="addPaper" parameterType="Paper">

        INSERT INTO paper(paper_id,name,number,detail) VALUE (#{paperId},#{paperName}, #{paperNum}, #{paperDetail})

    </insert>

    <delete id="deletePaperById" parameterType="long">

        DELETE FROM paper WHERE paper_id=#{paperID}

    </delete>

    <update id="updatePaper" parameterType="Paper">

        UPDATE paper

        SET NAME = #{paperName},NUMBER = #{paperNum},detail = #{paperDetail}

        WHERE  paper_id = #{paperId}

    </update>

    <select id="queryById" resultType="Paper" parameterType="long">

        SELECT paper_id,name,number,detail

        FROM paper

        WHERE paper_id=#{paperId}

    </select>

    <select id="queryAllPaper" resultMap="paperResultMap">

        SELECT paper_id,name,number,detail

        FROM paper

    </select>

</mapper>

在resource/spring包下分别新建配置文件：spring-dao.xml , spring-mvc.xml , spring-service.xml

spring-dao.xml：（spring-mybatis整合配置文件）

<?xml version="1.0" encoding="UTF-8" ?>

4. 利用tomcat进行项目部署

下载安装 tomcat：tomcat 9 下载地址
IDEA配置tomcat：
点击上方的 Run 选项，选择Edit Configuration

选择default -> tomcat -> local 选择下载安装到本地的tomcat服务器的地址

切换到Deployment选项页点击 + 号选择 Arctifact ，

添加项目名:war exploded 打包

最后在Application context 中选择空白那一项，点击 Apply 应用。

最后切换到index.jsp界面，右键运行项目

5. 运行界面

论文列表界面：

新增论文界面：

论文修改界面：

至此，利用IDEA+Maven+SSM框架实现的简单的增、删、改、查功能已经构建完毕！
