Question

我是heroku的新手，最近我在spring mvc上使用java配置构建了一个简单的应用程序。

所以我使用github在heroku上部署了这个应用程序。

我使用mysql作为数据库。

我的连接看起来像这样： -

 @Bean
    public DataSource dataSource() throws URISyntaxException {
        URI dbUri = new URI(System.getenv("CLEARDB_DATABASE_URL"));

        String username = dbUri.getUserInfo().split(":")[0];
        String password = dbUri.getUserInfo().split(":")[1];
        String dbUrl = "jdbc:mysql://eu-cdbr-west-
        01.cleardb.com:3306/heroku_eb3825f7cae7006?reconnect=true";

        DriverManagerDataSource dataSource = new DriverManagerDataSource();
        dataSource.setUrl(dbUrl);
        dataSource.setUsername(username);
        dataSource.setPassword(password);

        return dataSource;
    }

该应用已成功部署，我可以查看登录页面。我连接数据库以检查是否所有表都是自动创建的。创建了所有表，所以我在user和user_role表中插入了一些值，但现在当我尝试登录时，我无法登录。

错误日志说： -

heroku无法从表中选择（访问被拒绝）
