ssm整合筆記（配置檔案

建立資料庫

基本環境搭建

連接配接資料庫

bd.properties

jdbc.driver=com.mysql.jdbc.Driver
# mysql8.0+s需要加入一個時區配置：  ?serverTimezone=UTC
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild
jdbc.username=root
jdbc.password=Wjy12300.

包目錄結構
- mapper
- service
- controller
- pojo

resources

mybatis-config.xml （mybatis核心配置

<!--
	1. 配置typeAliea 面向pojo
	2. 配置映射到哪個mapper.xml

          4. 根據sqlSession對象建立sqlSessionTemplate對象
          5. 為mapperImpl中的對象注入值
          6. 設定自動掃描 ma p層包中的類 注冊到spring中
