本文主要记录自己初次使用idea搭建SSM框架项目的步骤，参考了https://blog.csdn.net/khxu666/article/details/79851070，供新手学习，项目结构如下：

新建文件夹时，可通过下图选择文件夹属性
在这里插入图片描述

一、创建maven项目

  1. File -> New->project，进入创建项目窗口，然后进行下图所示操作。
    在这里插入图片描述
  2. 点击Next，填写GroupId、ArtifactId和Version
    在这里插入图片描述
  3. 我们在弹出的框中输入Name为archetypeCatalog，Value为internal。（不加这个参数，在maven生成骨架的时候将会非常慢，有时候会直接卡住。 archetypeCatalog表示插件使用的archetype元数据，不加这个参数时默认为remote，local，即中央仓库archetype元数据，由于中央仓库的archetype太多了，所以导致很慢，指定internal来表示仅使用内部元数据。)

二、各项配置文件

        SELECT paper_id,name,number,detail
        FROM paper

三、类与接口

在controller包中新建PaperController.java

package com.chby.controller;

import com.chby.pojo.Paper;
import com.chby.service.PaperService;
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;

import java.util.List;

@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dao包中新建PaperDao接口

package com.chby.dao;

import com.chby.pojo.Paper;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public interface PaperDao {
    int addPaper(Paper paper);

    int deletePaperById(long id);

    int updatePaper(Paper paper);

    Paper queryById(long id);

    List<Paper> queryAllPaper();


}

在pojo包中新建Paper.java

package com.chby.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;
    }

}

在service包中新建PaperService接口

package com.chby.service;

import com.chby.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();
}

然后在service包中新建包impl，在impl包中新建PaperServiceImpl.java

package com.chby.service.impl;

import com.chby.dao.PaperDao;
import com.chby.pojo.Paper;
import com.chby.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();
    }

}

四、编辑JSP文件

index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
         pageEncoding="UTF-8" %>
<%
    pageContext.setAttribute("path", request.getContextPath());
%>
<!DOCTYPE HTML>
<html>
<head>
    <title>首页</title>
    <style type="text/css">
        a {
            text-decoration: none;
            color: black;
            font-size: 18px;
        }

        h3 {
            width: 180px;
            height: 38px;
            margin: 100px auto;
            text-align: center;
            line-height: 38px;
            background: deepskyblue;
            border-radius: 4px;
        }
    </style>
</head>
<body>
<div class="container">
    <div class="row clearfix">
        <div class="col-md-12 column">
            <div class="page-header">
                <h1>
                    基于SSM框架的管理系统：简单实现增、删、改、查。
                </h1>
            </div>
        </div>
    </div>
</div>
<br><br>
<h3>
    <a href="${path }/paper/allPaper">点击进入管理页面</a>
</h3>
</body>
</html>

在WEB-INF下新建jsp文件夹，在其中新建allPaper.jsp，addPaper.jsp，updatePaper.jsp
allPaper.jsp
