本文详细介绍了如何使用IntelliJ IDEA（idea）从零开始搭建一个SSM（Spring、SpringMVC、Mybatis）框架的项目。步骤包括创建Maven项目、配置项目文件、设置数据库连接、配置日志、编写工具类，以及测试项目的运行。通过这个过程，读者可以了解SSM框架的基础配置和项目结构。

使用idea搭建一个ssm框架（spring、springmvc、mybatis）

前言
创建项目
配置项目
- 工具类说明
编写测试项目代码
创建测试类进行测试
控制器层

前言

此篇博客用于记录博主自己搭建一个ssm框架的所有过程，由于配置文件都放置其中，博客较长，配置文件比较少做修改，可以略过，修改了的都做了说明。

创建项目

Maven=》选中Create from archetype=》选中在这里插入图片描述

在这里插入图片描述
第一个不用选，第二个项目名，第三个是项目路径，第四个域名反写，第五个和项目名一致，第六个版本号

在这里插入图片描述

第一个maven路径，第二个maven的setting.xml路径，第三个本地仓库路径，再把原本的archeVersion改成以下
在这里插入图片描述
然后Finish即可

等待片刻

在这里插入图片描述
右击src新建项目文件夹（Directory）,他会自动出现需要的文件夹，将其全新建

在这里插入图片描述
如下图：

配置项目

准备好的配置文件：

编写测试项目代码

配置maven逆向工程Run==》Edit ConfigUrations

点击加号选择maven

在这里插入图片描述

mybatis-generator:generate -e

点击ok即可，选中刚配置的maven点击运行即可创建需要的实体类以及mapper.java、mapper.xml文件

建立完整项目包结构：

新建service：

BookMapper.java加上注解：

package com.zengjing.mapper;

import com.zengjing.model.Book;
import org.springframework.stereotype.Repository;

@Repository
public interface BookMapper {
    int deleteByPrimaryKey(Integer bookid);

    int insert(Book record);

    int insertSelective(Book record);

    Book selectByPrimaryKey(Integer bookid);

    int updateByPrimaryKeySelective(Book record);

    int updateByPrimaryKey(Book record);
}

IBookService：

package com.zengjing.service;

import com.zengjing.model.Book;
import org.springframework.transaction.annotation.Transactional;

/**
 * @author zengjing
 * @site https://blog.youkuaiyun.com/JiangHu_Java
 * @create  2020-11-18 16:20
 */

@Transactional
public interface IBookService {

    int deleteByPrimaryKey(Integer bookid);

    int insert(Book record);

    int insertSelective(Book record);

    Book selectByPrimaryKey(Integer bookid);

    int updateByPrimaryKeySelective(Book record);

    int updateByPrimaryKey(Book record);
}

为IBookService新建实现类：

在这里插入图片描述

IBookServiceImpl：

package com.zengjing.service.impl;

import com.zengjing.mapper.BookMapper;
import com.zengjing.model.Book;
import com.zengjing.service.IBookService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

/**
 * @author zengjing

 */

@Service("BookService")
public class IBookServiceImpl implements IBookService {

    @Autowired
    private BookMapper bookMapper;

    @Override
    public int deleteByPrimaryKey(Integer bookid) {
        return bookMapper.deleteByPrimaryKey(bookid);
    }

    @Override
    public int insert(Book record) {
        return bookMapper.insert(record);
    }

    @Override
    public int insertSelective(Book record) {
        return bookMapper.insertSelective(record);
    }

    @Override
    public Book selectByPrimaryKey(Integer bookid) {
        return bookMapper.selectByPrimaryKey(bookid);
    }

    @Override
    public int updateByPrimaryKeySelective(Book record) {
        return bookMapper.updateByPrimaryKeySelective(record);
    }

    @Override
    public int updateByPrimaryKey(Book record) {
        return bookMapper.updateByPrimaryKey(record);
    }
}

创建测试类进行测试

    @Test

        Book book=this.bookService.selectByPrimaryKey(1);
        System.out.println(book);
