idea插件开发笔记——右键菜单添加自定义模板

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

2. 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>
   

3. 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);
           }
