mybatis自动生成代码无法生成，原因连接数据库失败

1.执行命令： mvn mybatis-generator:generate

2.报错信息：

Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

3.解决方法：在数据库连接处添加

&useSSL=false     或   &useSSL=false

4.总结：

SSL(Secure  Sockets Layer)，安全套接字协议。useSSL=false:使用用户账号密码进行连接。
