IDEA搭建SSM-Maven版
一、項目準備
1.準備工作
本次搭建是基於IDEA創建Maven項目-Web版之上進行搭建的，由於內容重複，故在此不做累贅直接跳過此部分工作。我這裏的項目名是：MavenSSMDemo，你可以使用你自己的項目名稱。
不知道如何使用Maven創建Web項目的小夥伴可移步：
IDEA創建Maven項目-Web版
2.完善項目
1.新建Java源代碼文件夾，用來保存Java代碼。操作流程：1.在main上右鍵->New->Package->填入Java->Java右鍵->Mark Directory as->Resource Root
2.新建views文件夾來保存jsp頁面，添加的位置是在WEB-INF之下。
3.項目截圖
上面都已經做好之後，項目的文件夾結構基本完整。下面跟着我一步步來搭建，要是有問題可以聯繫我，一般都是下班之後會給你回覆。
二、創建項目
1.配置文件
1.user.mapper.xml
resouces下新建mapper文件夾，用來保存實體類的xml配置文件，在mybatis掃描的時候可以掃描到。
<?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.sjsq.model.user.mapper">
<select id="list" resultType="User">
select * from user;
</select>
<select id="selectUser" resultType="User">
select * from user where id=#{id};
</select>
</mapper>

三、數據庫文件
drop database if exists maven-ssm-demo;
create database maven-ssm-demo;
drop table if exists `user`;
create table `user` (
`id` int(11) not null auto_increment,
`username` varchar(255) default null,
`password` varchar(255) default null,
primary key (`id`)
);
insert into `user` values (1, 'sjsq', '123456');
四、運行項目
瀏覽器輸入：http://localhost:8080/list.do，就可以訪問到頁面了。
五、感悟及其他
1.感悟
SSM搭建過程，主要是配置文件要寫正確。其次，要注意數據庫的配置，這裏使用的mysql8.0。其他就沒有什麼了。但是要理解SSM原理是較爲複雜的，如果要是再讀源碼，要求就要更高。
2.商務合作
