可以以如下为例子进行配置

 String dbURL = "jdbc:mysql://localhost:3306/databaseName?useSSL=false&&allowPublicKeyRetrieval=true&&useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT";
    String userName = "root";
    String passWord = "password";
    Class.forName("com.mysql.cj.jdbc.Driver");
    Connection connection = DriverManager.getConnection(dbURL, userName, passWord);
