idea插件开发笔记——右键菜单添加自定义模板

再resources文件下创建fileTemplates/internal文件夹（必须是这个）

添加模板文件 mapper.tsx.ft

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="${NAMESPACE}" >
</mapper>

创建右键菜单mapper模板创建

      //读取模板
        FileTemplate template = FileTemplateManager.getInstance(project)
                .getInternalTemplate("mapper");
        Properties properties = new Properties();
        //替换模板里的参数
        properties.setProperty("NAMESPACE", "");
        String renderedText = "";
        try {
            renderedText += template.getText(properties);
        } catch (IOException ex) {
            throw new RuntimeException(ex);
        }

        PsiFile psiFile = PsiFileFactory.getInstance(project).createFileFromText("mapper.xml", XMLLanguage.INSTANCE, renderedText);
        System.out.println(psiFile.isPhysical());
        try {
            //执行写入文件
            Runnable runnable = () -> psiElement.add(psiFile);
            //调度任务
            WriteCommandAction.runWriteCommandAction(project, runnable);
        } catch (Exception exception) {
            //文件存在，会抛错；idea发送通知
            NotificationGroup notificationGroup = new NotificationGroup("testid", NotificationDisplayType.BALLOON, false);
            Notification notification = notificationGroup.createNotification("File already exists", MessageType.INFO);
            Notifications.Bus.notify(notification);
        }
