CodeMaker

A idea-plugin for Java/Scala to generate code, support custom code template.

This plugin generates code from right click 'Generate...' menu while focused on a Java/Scala class. The output class can be customized using a provided velocity template to format the code based on the origin class and optional selected classes. There are many features are contributed by Dmitry Karlinsky and I appreciate that.

The following features are available:

Support add custom template to generate more code.(Velocity templates and groovy templates)
Generate the model class for the persistent class.
Generate the converter class for the model class and the persistent class.
Generate @see doc for override method.
Support Scala.
Generate api table from code

Install

Usage

This plugin generates code from right click 'Generate...' menu while focused on a Java/Scala class.

The plugin support multiple class to generate one code, you can set the class number of template to select multiple classes to use.

Configuration

Add template: click "Add Template" button to add a template, after saving changes.
Delete template: click "Delete Template" button to delete a template.

classNumber: The template context will contain the class which user select when trigger the generate action. for example, the number is 1, the template context only has the focused class: $class0; if the number is 2, when you trigger the generate action, you need select a class, then the template context will have two class entry: $class0, $class1
className: The class name support velocity and the template context.

Advance

If you want to add variables into template context, you can modified the source and package the plugin to meet your needs.

The injection of template context is executed by com.xiaohansong.codemaker.action.CodeMakerAction.generateCode

private String generateCode(CodeTemplate codeTemplate, List<ClassEntry> selectClasses) {
        Map<String, Object> map = new HashMap<>();
        for (int i = 0; i < selectClasses.size(); i++) {
            map.put("class" + i, selectClasses.get(i));
        }
        Date now = new Date();
        map.put("class", selectClasses.get(0));
        map.put("YEAR", DateFormatUtils.format(now, "yyyy"));
        map.put("TIME", DateFormatUtils.format(new Date(), "yyyy-MM-dd HH:mm:ss"));
        map.put("USER", System.getProperty("user.name"));
        String className = VelocityUtil.evaluate(codeTemplate.getClassNameVm(), map);
        map.put("ClassName", className);
        map.put("utils", new Utils());
        map.put("BR", "\n");

        return VelocityUtil.evaluate(codeTemplate.getCodeTemplate(), map);
    }
