主机名 : localhost
端口 : 3306
数据库名:mysql
在网上搜了好多都说mysql-connector-java-5.1.26-bin没有在/data-integration/lib或者/data-integration/libswt/win64/下
但是上图可以看出我的jar包已在/data-integration/lib下
最后，解决方法是：
1. root使用密码123456（密码自己设置强度高点）从任何主机连接到mysql服务器的话。
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec) mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
2. 允许用户root从的主机连接到mysql服务器，并使用123456作为密码
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '' WITH GRANT OPTION;
Query OK, 0 rows affected (0.00 sec) mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)
3. 允许用户root从ip为127.0.0.2的主机连接到mysql服务器的dk数据库，并使用123456作为密码
mysql> GRANT ALL PRIVILEGES ON dk.* TO 'root'@'127.0.0.2' IDENTIFIED BY '' WITH GRANT OPTION; Query OK, 0 rows affected (0.00 sec) mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.00 sec)
授权完成后，再一次连接成功。
