我正在尝试在我的计算机上本地运行jhipster应用程序。我已经安装了mysql服务器和 .sql 通过mysql workbench导入的文件。
但是，每次我跑 mvnw 在项目目录中，我得到：

我的数据库中的数据源信息 application-dev 文件中有以下几行对应于在我的电脑上设置的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:

                cachePrepStmts: true

                prepStmtCacheSqlLimit: 2048
                useServerPrepStmts: true
