使用springboot加逆向工程genertor注意如果生成多次需要删除原来的mapper.xml 否则会重复 无法注入而且提示 not found bean....

1.在dao上@Mapper与 run（）主程序@MapperScan注解是等同的,dao 和mappexml的文件位置也需要配置好

spring.datasource.url = jdbc:mysql://localhost:3306/menhu?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT%2B8

spring.datasource.username = root

spring.datasource.password = 123456

spring.datasource.driverClassName  = com.mysql.cj.jdbc.Driver

spring.datasource.max-active=20

spring.datasource.max-idle=8

spring.datasource.min-idle=8

spring.datasource.initial-size=10

logging.level.org.springframework.web=DEBUG
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
