  原文参考 这里 安装
  Add jcaptcha-all.jar (provided in bin-distribution) and ehcache.jar (not provided see ehcache site) to your application class path, ie in you WEB-INF/lib folder.
  
  实例一个jcaptcha服务，注意，必须是单例模式的
  import com.octo.captcha.service.image.ImageCaptchaService;
  import com.octo.captcha.service.image.DefaultManageableImageCaptchaService;
  
  public class CaptchaServiceSingleton {
      
      private static ImageCaptchaService instance = new DefaultManageableImageCaptchaService();
      
      public static ImageCaptchaService getInstance(){
          return instance;
      }
  }
