原 Spring + SpringMVC + Mybatis 整合，实现 CRUD (增删改查)
这次暑假在腾讯课堂学习了尚硅谷SSM整合视频（SSM开发是目前企业流行使用的框架整合方案）免费教程，该视频讲解了 Spring + SpringMVC + MyBatis 整合实现了 CRUD (增删改查)。将代码整理，运行成功后，写下这篇博文记录一下。
1.创建 Maven 项目，配置 Maven
maven 项目的目录
配置 maven 的 .m2（我的是 C:\Users\cjc.m2） 目录下的 settings.xml 文件
使用 使用阿里云的 maven 仓库
指定 jdk 的版本
2.在 pom.xml 引入 jar 包
配置 pom.xml

beans>5.MyBatis 逆向工程生成 mapper 和 xml 等文件，需要先创建两个表
DROP TABLE IF EXISTS `tbl_dept`;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `tbl_dept` (
`dept_id` int(11) NOT NULL AUTO_INCREMENT,
`dept_name` varchar(255) NOT NULL,
PRIMARY KEY (`dept_id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
LOCK TABLES `tbl_dept` WRITE;
INSERT INTO `tbl_dept` VALUES (1,'开发部'),(2,'测试部');
/*!40000 ALTER TABLE `tbl_dept` ENABLE KEYS */;
UNLOCK TABLES;
DROP TABLE IF EXISTS `tbl_emp`;
/*!40101 SET character_set_client = utf8 */;
CREATE TABLE `tbl_emp` (
`emp_id` int(11) NOT NULL AUTO_INCREMENT,
`emp_name` varchar(255) NOT NULL,
`gender` char(1) DEFAULT NULL,
`email` varchar(255) DEFAULT NULL,
`d_id` int(11) DEFAULT NULL,
PRIMARY KEY (`emp_id`),
KEY `fk_emp_dept` (`d_id`),
CONSTRAINT `fk_emp_dept` FOREIGN KEY (`d_id`) REFERENCES `tbl_dept` (`dept_id`)
) ENGINE=InnoDB AUTO_INCREMENT=1012 DEFAULT CHARSET=utf8;编译执行 MBGTest.java, 还有配置文件 mbg.xml, 可以得到 MyBatis 生成的 xml 和 mapper 文件。

<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%-- <%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> --%>
<%
pageContext.setAttribute("APP_PATH", request.getContextPath());
String path = request.getScheme() + "://" + request.getServerName()
+ ":" + request.getServerPort() + request.getContextPath()
+ "/";
System.out.println(path);
System.out.println("APP_PATH = " + pageContext.getAttribute("APP_PATH"));
%>
