我正在尝试在计算机上本地运行JHipster应用程序。我已经安装了MySQL Server，并通过MySQL Workbench导入了.sql文件。
但是，每次我在项目目录中运行mvnw时，都会得到：

我的application-dev文件中的数据源信息具有以下几行，分别对应于我的PC上设置的MySQL用户名和密码：
datasource:
url: jdbc:mysql://localhost:3306/myApp?useUnicode=true&characterEncoding=utf8&useSSL=false
name:
username: root
password: root
hikari:
data-source-properties:
