SpringBoot整合Myabtis报错：Access denied for user ‘root‘@‘localhost‘ (using password: YES)

错误原因： properties.yml文件中对特殊字符处理，可以使用双引号包裹起来作为字符解析

1. 密码未加双引号

 则报错  Caused by: org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

2.对密码加双引号

即解决
