抓取jsp页面生成图片

在anction中写的一方法：

public void aaa()throws Exception{

//String phoneIp=PropertiesUtil.getProperty("phoneIp");//phoneIp：在配置中配置的一个IP在地址

//request.getRemoteAddr();//得到当前的IP地址：得到的是IPv4或都是IPv6的

  String url  = this.getUrl();//用onload方法传入当前JSP页面的URL地址

//存放图片在本地

  //String filePath = PropertiesUtil.getProperty("url2jpgfilepath") + "//file.jpg";//设置图片存放位置（url2jpgfilepath：application.properties中配置的图片存放位置）

//存放在服务上

String filePath = request.getRealPath("resource/pic")+File.separator+user.getAdOrgId()+crmSelCheckId+".jpg";  new Url2Jpg(url, new File(filePath)).producePic();

//request.getRealPath("resource/pic"):得到服务上的一个地址

//File.separator:为加载斜线
 }

传URL地址：
