idea in code generation and reverse engineering plug-ins

mabatis-plus reverse engineering

1, mybatis-plus plug-ins

Install 1.1, mybatis-plus plug-in

mybatis-plus plug-in download: https: //zhile.io/2019/04/23/mybatis-code-helper-pro-crack.html

First download a good mybatis-plus plug-ins, and then choose to install plug-in from disk.

1.2, the data source connection

After a successful connection, shown in FIG.

1.3, using a single table to generate a single plug

Using the installed plug-ins automatically generated classes mybatis

Generation is complete, as shown in FIG.

1.4, using a plug-in generates multiple tables (recommended)

2, mybatis-plus automatically generated classes
