ssm,c3p0, Access denied for user 'xx'@'localhost' (using password: YES)

ssm整合的时候，用的c3p0连接池，数据库配置文件如下

database.properties

driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=false&serverTimezone= UTC&useUnicode=true&characterEncoding=utf-8&allowPublicKeyRetrieval=true
username=root
password=root

把username改成user即可

具体原因不知道，小白一枚
