Java调用计算机摄像头拍照实现过程解析

Java调用计算机摄像头照相（Rest API的页面操作）

使用开源组件webcam-capture：https://github.com/sarxos/webcam-capture

项目源码GitHub：https://github.com/muphy1112/RuphyRecorder

本例子使用基于Java rest API的页面操作，方便远程拍照

CameraApplication.java

package me.muphy;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class CameraApplication {

  public static void main(String[] args) {
    SpringApplication.run(CameraApplication.class, args);
  }

}

当前电脑没有摄像头，因此是正常的
