TSET类测试druid数据库连接池,执行结果拒绝访问，如何解决？(语言-java)

问题遇到的现象和发生背景

在idea中创建@TSET类测试druid数据库连接池,执行结果拒绝访问

问题相关代码，请勿粘贴截图

public class tb_brand {
    @Test
    public void testQuery() throws Exception {
        //1.导入jar包
        //2.定义配置文件
        //3. 加载配置文件
        Properties prop=new Properties();
        prop.load(new FileInputStream("C:\\Users\\Administrator\\IdeaProjects\\jdbc\\jdbc-demo"));
        //4. 获取连接池对象  固定对象DruidDataSourceFactory
        DataSource dataSource = DruidDataSourceFactory.createDataSource(prop);
        //5. 获取数据库连接 Connection
        Connection connection = dataSource.getConnection();
        //System.out.println(connection); //获取到了连接后就可以继续做其他操作了
        //6.定义SQL语句
        String sql ="select *from tb_brand";
        //7.获取pstmt对象
        PreparedStatement pstmt = connection.prepareStatement(sql);
        //8.设置参数
        //9.执行sql语句
        ResultSet rs = pstmt.executeQuery();
        ArrayList brands=new ArrayList<>();
        while (rs.next()){
            int id=rs.getInt("id");
            String brandName=rs.getString("brand_name");
            String companyName = rs.getString("company_name");
            int ordered = rs.getInt("ordered");
            String description = rs.getString("description");
            int status = rs.getInt("status");
            Brand brand=new Brand(id,brandName,companyName,ordered,description,status);
            brands.add(brand);
        }
        System.out.println(brands);
    }
}

运行结果及报错内容

我的解答思路和尝试过的方法

刚入门,所以没有方向

我想要达到的结果

请问是否跟权限有关,需要更改什么配置

账号权限问题，账号的配置的访问host配置改成*所有可以访问，其次账号也要开对应的操作权限
