com.centit.support.image.CaptchaImageUtil

public abstract class CaptchaImageUtil
extends Object

对辨析难度要求高的可以用 google的kaptcha ， 这个类设计就是为了辨析容易，哈哈虽然有点搞笑，但是有的用户就是有这个要求 google的kaptcha 是用方法 ，先配置bean 在类中注入这个bean 然后调用 BufferedImage bi = captchaProducer.createImage(String captchaKey);方法 着用用法就和CaptchaImageUtil的generateCaptchaImage 方法一致了
