Wildfly 休眠无法创建数据库连接

Question

我是整个widlfly-hibernate的新手，在工作中我们使用tomcat-mybatis

我正在尝试使用 Hibernate 5.1.0 将 Wildfly 10.0 与 MySQL 连接

我如何连接：

try {
            Configuration configuration = new Configuration();

            configuration.setProperty("hibernate.connection.driver_class", "com.mysql.jdbc.Driver");
            configuration.setProperty("hibernate.connection.url", "jdbc:mysql://127.0.0.1:3306/foxtrot");
            configuration.setProperty("hibernate.connection.username", "root");
            configuration.setProperty("hibernate.connection.password", "");
            configuration.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
            configuration.setProperty("hibernate.current_session_context_class", "thread");
            configuration.setProperty("hibernate.id.new_generator_mappings", "false");
            configuration.setProperty("hibernate.show_sql", "true");

            configuration.addAnnotatedClass(AccountEntity.class);

            StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder()
                    .applySettings(configuration.getProperties());
            return configuration.buildSessionFactory(builder.build());
        } catch (Throwable ex) {
            // Make sure you log the exception, as it might be swallowed
            System.err.println("Initial SessionFactory creation failed." + ex);
            System.out.println(ex.getStackTrace());
            System.out.println(ex.getMessage());
            throw new ExceptionInInitializerError(ex);
        }

我收到以下错误：org.hibernate.exception.JDBCConnectionException: Error calling Driver#connect

Sql 异常：java.sql.SQLNonTransientConnectionException: Could not create connection to database server.

我正在使用 wamp，我已经预安装了 phpmyadmin，我可以毫无问题地连接

问题来自我以前在 5+ mysql 服务器上使用 6.0.2 的 mysql 连接器驱动程序，现在我使用驱动程序 5.+ 并且一切正常
