之前一直好好的，今天不知道删了什么，然后运行就报错了。其他项目运行也报一样的错。卡一上午了
1. 报错代码
2. application.yml
#端口号 server: port: 8888 #服务名 spring: datasource: driverClassName: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/day8_mybatis_1103?useUnicode=true&characterEncoding=utf8 username: root password: '1234' druid: #druid 连接池配置 initial-size: 1 #初始化连接池大小 min-idle: 1 #最小连接数 max-active: 20 #最大连接数 test-on-borrow: true #获取连接时候验证，会影响性能
3. pom.xml
