The template engine configuration is not mentioned in the official documentation, so you will need to download the template after you create the code generator using the tutorial:
- Open the link to download the zip package
- Unzip to find the file that will
mybatis-plus-generator/src/main/resources/templates
Copy to your own project - You can then specify the template path in the code generator, for example
String templatePath = "/templates/mapper.xml.ftl";
