mybatis的逆向工程

问题：

Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.6:generate (default-cli) on project adapt: 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.

解决方法：

connectionURL加上  ?serverTimezone=UTC

还有  useSSL=false&

 

?useSSL=false&serverTimezone=Asia/Shanghai&characterEncoding=utf8&useUnicode=true

 

问题：

[ERROR] Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.6:generate (default-cli) on project adapt: Unsupported character encoding 'utf8?serverTimezone=UTC'

解决方法：

写成下面这样

?serverTimezone=UTC&characterEncoding=utf-8

以上都没有解决我的问题，但是还是能解决此类问题的

怀疑是数据库的原因

用逆向工程生成的mapper.xml文件要注意delete方法，最好重新写一下
