+# 由于工作中的需求，需要用java来实现当前电脑的录屏功能以及屏幕的截图截屏功能
* 由于习惯了springboot 所以就写在springboot上了，并暴露了一个接口来触发录屏功能
* 核心代码在fxbase包下的VideoRecorder类中 但是代码写的有点乱，使用者可以不必过度关注这个类 而是看看RecorderUtil，我将这个类注入到了ioc容器，这个类的getVideoRecorderInstance可以获取录屏对象 调用这个对象的start()和stop()方法来完成录制和结束，具体过程很简单，可以看RecorderController的调用过程
@@ -19,3 +19,5 @@
* ####注意：主函数的启动类不是SpringApplication.run(DemoApplication.class, args);不然触发录屏会报错。而是SpringApplicationBuilder builder = new SpringApplicationBuilder(VideoRecordeApplication.class);
builder.headless(false).run(args);
