- 正常創建一個maven專案，環境是jDK1.8及以上，maven3.8及以上
- 無論SSM專案、SpringBoot專案還是SpringCloud專案第一件事就是添加相關的依賴，這里是針對SSM整合匯入相關的依賴

- 剛創建的maven專案是沒有web.xml檔案的（如果有就更好，是在webapp/WEB-INF目錄下哦），如果沒有，就要按照如下步驟添加
- 點擊File->Project Structure->Facets
- 點擊File->Project Structure->Facets
- web.xml配置的內容基本上就是Servlet程式的三大組件：
Listener監聽器、DispatcherServlet程式（控制器）、Filter過濾器，

- 寫到這里你肯定會發現有一個地方會報紅，那就是缺少了Spring組態檔
applicationContext.xml，其實applicationContext.xml組態檔
就是Spring組態檔的一部分，因為Spring要與Mybatis整合，Spring組態檔一分為二，一部分是Spring與Mybatis整合的組態檔applicationContext.xml，一部分是
Spring與SpringMvc的組態檔dispatcherServlet.xml，- applicationContext.xml
- 另外還需要在類路徑下創建一個mapper的目錄

- 這個配置組態檔的作用主要是Mybatis的全域配置，如物體型別別的別名、駝峰式命名
- mybatisConfig.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="https://www.cnblogs.com/aitiknowledge/archive/2022/07/21/true"/>
</settings>
<!-- 設定型別別名 -->
<typeAliases>
<package name="com.xsha.ssm.entity"/>
</typeAliases>
</configuration>
- 同樣，上面還是缺少了一個組態檔，就是連接資料庫的組態檔
jdbc.properties
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql:///database_name?useUnicode=true&characterEncoding=utf8
jdbc.username=username
jdbc.password=password
- 到這里，就已經實作了Spring和Mybatis的整合，接下來就是實作Spring和SpringMvc的整合，在上面的web.xml就基本配置完成Spring和SpringMvc的整合，
就差一個視圖決議器的組態檔dispatcherServlet.xml
<?xml version="1.0" encoding="UTF-8"?>

<!-- SpringMvc的組態檔，包括網站跳轉邏輯控制 -->
<context:component-scan base-package="com.xsha.ssm" use-default-filters="false">
<!-- 只能掃描控制器 -->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller" />
</context:component-scan>
<!-- 配置視圖決議器 -->
<bean >
<property name="prefix" value="https://www.cnblogs.com/WEB-INF/views" />
<property name="suffix" value="https://www.cnblogs.com/aitiknowledge/archive/2022/07/21/.jsp" />
</bean>
<!-- 兩個標準配置 -->
<!-- 將SpringMvc不能處理的交割tomcat處理 -->
<mvc:default-servlet-handler />
<mvc:annotation-driven />
</beans>
- SSM的整合已經實作，大家可通過單元測驗
