数据库没有开启时 不同场景报的错

 

 

Failed to execute goal org.mybatis.generator:mybatis-generator-maven-plugin:1.3.2:generate (default-cli) on project mybatis-generator: 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.

在写mybatis代码生成器的时候 给我报了一个这个错，原因就是你的数据库没有启动
