IDEA Code Automatically Generate Plugin • For Java Version



The latest version is 4.1 is approved by the official on 10th, May.
If you can't fetch it, then click here to download .zip file.
Important: This version has been implemented DSP(D8ger Series Plan).
That is, some functions have been migrated to another plugin named LaoYouTiao. After testing, installing two plugins will not affect performance. So, I hope you use happy and give me a 🌟, thx!


As JetBrains' said, I believe that you should be good use of tools will save you precious hours on your busing work.

I always wonder, "If someone else has already solved the repeating work, why do I need to repeat it again?"

Well, that's a valid question for my drive to find the repeat parts at daily work and develop this plugin to save my time.

Quick Start



  • The general problem provides standard solutions
  • The personalized problem only provides example solutions

Original design intention

  • Remove the fixed duplication coding for improving efficiency in development
  • Provide available code templates that can be used without modification
  • Support code directory configuration, only by self-guided package intelligent programming can be done in one-click
  • Support user-defined configuration, you can specify which file to be generated


  • Camel-Underline-Uppercase-Uncapitalize-Lowercase can be converted to each other by shortcut alt + shift + cmd + U
  • The comments of generated codes support English(Default) | Chinese Simplified(Optional) configuration
  • JSON formatting and single line text conversion, supporting section and whole document, default shortcut alt+shift+cmd+J | S
  • Generating data table definition SQL | Mo | Mapper | Handler, single table addition, deletion, modification and search with paging in one click
  • Under the help of SwaggerApi generating Vo | Controller with friendly document description, in addition to this, supporting Vo field automatic sorting
  • For smart coding, you just need one shortcut default as alt+shift+cmd+D
  • Supporting customer configuration, for example, specify the author who you are
  • Reserve easter eggs, you can try to edit the blank file in IDEA and type d8ger to get the default configuration template
  • Reserve easter eggs, edit the blank file in IDEA and enter nasa to get the NASA configuration file template. This is very useful and efficient for handling multi-lines, especially SQL field naming processing.
  • Reserve easter eggs, edit the blank file in IDEA and enter regex to get some commonly used regular expressions. Other code Easter eggs will be added later.
  • For automatic sorting Vo field , you just need one shortcut default as alt+shift+cmd+O

Using manual(v3.0+)

1.Open the configuration box to set the generation parameters, Preference --> Other Settings --> D8gerAutoCode

2.Check the file to be generated and choose the generation path, rewrite authorapiUrlPrefix and locale, and click the button to save your configuration.

Using manual(under v3.0)

  1. Create Model Class

  2. Select the class name and press the (default) shortcut alt+shift+cmd+D

  3. Under the default configuration, D8gerAutoCode directory and data table SQL definitions and Web codes will be generated

  4. So, What you need to do:

    • Under a multi-module project, configure the generated file output directory, for example, should be moved into the model directory
    • Add non-null constraints to xx.sql as required
    • If you generated the file, please note the interface returns type of Object, it should be modified to the project's uniform return type
    • In the above steps the file will report some errors, don't worry, these just require you to import packages
  5. Default configuration file template for easter egg:

    • In the resource root directory of the module where the Model class is located, create property configuration file
    • Type d8ger and click on Tools-> D8ger-> D8gerMore, and you will find some surprise
  6. Regex template for easter egg:

    • Choose any blank file, Type regex and click on Tools-> D8ger-> D8gerMore, and you will find some surprise
  7. NASA template for easter egg:

    • Choose any blank file, Type nasa and click onTools-> D8ger-> D8gerMore, and you will get the NASA manual
    • Follow the manual, custom your config and write your own multi-lines need to be batch handled, then you will find some surprise
  8. Camel-Underline-Uppercase-Uncapitalize-Lowercase circle convert by one-click

    • Choose word text in any editing file, press alt + shift + cmd + U, you`ll find the changed word
    • If not satisfied just press the shortcut again and again util you are.
  9. You will get the following default configuration information

    • It's recommended that you change the configuration items
      • author (you can't sign my name for the pits you dug!)
      • apiUrlPrefix (the interface url prefix should be configured as the project interface unified URL prefix)
      • generate file output directory under a multi-module project
    • As for boolean configuration items, let you choose which files need to be generated, and specify output directory is optional

By the way, these default shortcuts used in Mac OS, if you use Windows just take cmd into ctrl.

How to install

  • Preference --> Plugins --> Marketplace --> type D8 --> install
  • IDEA official plugin library installation
  • As for Source installation requires you're familiar with Gradle, I will add more details about how to develop a plugin by Gradle later

Bug & Question

  • Known issues

Modify the file before generating code, the configuration file does not take effect

0. If you upgrade version 3.0+, you won`t see it again.
1. Because the IDEA file uses the VFS mechanism, as a plug-in to use the monitoring file I think it is not cost-effective  
2. I also found a reason aboub editing .properties file, sometimes it will take one or two minutes to refresh after you finished  
3. So, press `cmd` + `s` to force refreshing .properties file and you will solve it.

The icon of plugin shows error like this: red square with a cross

1.This issue is caused by Intellij IDEA of new version feature.
2.Try to upgrade the version of Intellij util 2019.3.*(greater than 2019.2.*), you'll fix it.
