6.注意
1.申明扫描bean的位置，否则无法初始化bean

2.申明dao接口的位置和xml的位置

3.在web模块的appliaction.properties申明数据库相关信息
server.port=9005
logging.level.com.cwh.webProject=debug
spring.datasource.driverClassName = com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test?serverTimezone=GMT&useSSL=false
spring.datasource.username=root
spring.datasource.password=
mybatis.type-aliases-package=com.api.bean
mybatis.mapper-locations: classpath:com.api.dao/*Mapper.xml
