java验证码kaptcha自定义

1、生成中文字符串，主要是实现TextProducer

public   class   ChineseTextProducer    implements   TextProducer

{

privateString[] simplifiedChineseTexts=newString[]{

"包括焦点","新道消点","服分目搜","索姓名電","子郵件信","主旨請回","電子郵件","給我所有","討論區明","發表新文","章此討論","區所有文","章回主題",

"樹瀏覽搜"

};

/**

*@returnrandom Chinese text

*/

publicStringgetText()

{

returnsimplifiedChineseTexts[newRandom().nextInt(simplifiedChineseTexts.length)];

}

}

2、第二步是应用自定义的ChineseTextProducer

properties.setProperty("kaptcha.textproducer.impl","包名ChineseTextProducer ");

3、自己实现的数字相加的验证码

import com.google.code.kaptcha.text.TextProducer;

import java.util.Random;

public class ArithmeticTextProducerimplements TextProducer {

private int[]simplifiedNumber =new int[]{

0,1,2,3,4,5,6,7,8,9

    };

    private  StringcreateNumberText(){

return Integer.toString(simplifiedNumber[new Random().nextInt(simplifiedNumber.length)]);

    }

public StringgetText(){

return createNumberText()+"+"+createNumberText()+"=?";

    }

}
