Use mybatis-generator generator

The record about how to use this plug-in, first of all declare that I use is springboot.

This is mainly to note that the profile generatorConfig.xmllocation, is my comment that line. I put the pom configuration files and files in the same directory. Also recommended that all do, behind the configuration file can be changed a little less.

2. Configure generatorConfig.xml

Then modify the configuration file, so a few major changes:

• jdbc driver position
• Database connection information
• Entity class, dao, package path and the xml file path.

If your profile generatorConfig.xmlis also on the same level and pom directory, where the file path is not how need to move, change it as long as the package path.

generatorConfig.xml

3. Run the plug

In front are configured correctly, run the plug-in here just fine.
