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。

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" ?>

• 在jdbc.properties文件中配置mysql数据库（这里的数据库名、表名，用户名，密码一定要记得修改！！！）。

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/papersystem?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=12345678

• 在log4j.properties文件中配置日志设定

log4j.rootLogger=ERROR, stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

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！
