*  ?SSM整合流程
 *   *  一、两个容器整合✨
     *   *   1、先准备好数据库config.properties连接、mybatis-config.xml?
         *   2、容器一：优先配置spring.xml文件?
         *   3、容器二：配置springMVC.xml文件?
         *   4、Tomcat整合spring容器、springMVC容器，webapp文件下的web.xml文件?
     *  二、一个容器整合
     *   *  1、 现在去掉了spring.xml文件，将spring.xml文件的内容放到springMVC?
         *   2、Tomcat整合springMVC容器，webapp文件下的web.xml文件?

`注意：优先maven项目的pom.xml文件里导入jar包依赖：`

### 一、两个容器整合✨ ###

####  1、先准备好数据库config.properties连接、mybatis-config.xml? ####

（1）数据库config.properties连接

driver=com.mysql.cj.jdbc.Driver
    url=jdbc:mysql://localhost:3306/emp?serverTimeZone=Asia/ShangHai&useUnicode=true&characterEncoding=utf8&useSSL=false
    username=root
    password=nigx=0128

（2）mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
    <!DOCTYPE configuration
            PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
            "http://mybatis.org/dtd/mybatis-3-config.dtd">
    
    <configuration>
    
        
        
    
        <settings>
            
            <setting name="mapUnderscoreToCamelCase" value="true"/>
            <setting name="logImpl" value="STDOUT_LOGGING"/>
            
            
        </settings>
    
        
        <typeAliases>
            <package name="com.pojo"/>
        </typeAliases>
    
        
        
        
        
        
        
        
        
    
        
        
        
        
        
        
        
        
        
        
        
        
    
    
        <mappers>
            
            
    
            
            
        </mappers>
    </configuration>

####  2、容器一：优先配置spring.xml文件? ####

    </beans>

####  3、容器二：配置springMVC.xml文件? ####

####  4、Tomcat整合spring容器、springMVC容器，webapp文件下的web.xml文件? ####

### 二、一个容器整合 ###

#### 1、 现在去掉了spring.xml文件，将spring.xml文件的内容放到springMVC? ####

`springMVC.xml文件如下：`

####  2、Tomcat整合springMVC容器，webapp文件下的web.xml文件? ####
