Spring mvc框架下使用kaptcha生成验证码

1、下载jar包并导入。

　　kaptcha-2.3.2.jar

2、spring 配置文件 applicationContext.xml。

    <bean id="captchaProducer" class="com.google.code.kaptcha.impl.DefaultKaptcha">

        <property name="config">

            <bean class="com.google.code.kaptcha.util.Config">

                <constructor-arg>

                    <props>
                        <prop key="kaptcha.image.width">65</prop>
                        <prop key="kaptcha.image.height">30</prop>
                        <prop key="kaptcha.textproducer.font.size">25</prop>
                        <prop key="kaptcha.textproducer.font.color">red</prop>
                        <prop key="kaptcha.textproducer.font.names">Arial</prop>
                        <prop key="kaptcha.textproducer.char.string">123456789</prop>
                        <prop key="kaptcha.textproducer.char.length">4</prop>
                        <prop key="kaptcha.obscurificator.impl">com.google.code.kaptcha.impl.ShadowGimpy</prop>
                        <prop key="kaptcha.noise.impl">com.google.code.kaptcha.impl.NoNoise</prop>

                    </props>

                </constructor-arg>

            </bean>

        </property>

    </bean>

配置项如下：

3、jsp页面。

    <script type='text/javascript'  src='${base}/js/jquery-1.10.2.min.js'></script>

    <script type="text/javascript">      

        $(function(){

        $('#kaptchaImage').click(function () {//生成验证码

             $(this).hide().attr('src', '${base}/captcha-image.htm?' + Math.floor(Math.random()*100) ).fadeIn();

             event.cancelBubble=true;

            });

        }); 

        function changeCode() {

            $('#kaptchaImage').hide().attr('src', '${base}/captcha-image.htm?' + Math.floor(Math.random()*100) ).fadeIn();

            event.cancelBubble=true;

        }

   </script>

    <div class="chknumber">

          <label>验证码:

              <input name="kaptcha" type="text" id="kaptcha" maxlength="4" class="chknumber_input" />

          </label>

          <br />

          <img src="${base}/captcha-image.htm" id="kaptchaImage"  style="margin-bottom: -3px"/>

          <a href="#" onclick="changeCode()">看不清?换一张</a>

    </div>

4、创建验证码生成控制类CaptchaImageCreateController.java。

import java.awt.image.BufferedImage;

import javax.imageio.ImageIO;

import javax.servlet.ServletOutputStream;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

import com.google.code.kaptcha.Constants;

import com.google.code.kaptcha.Producer;  

@Controller

@RequestMapping("/")

public class CaptchaImageCreateController {  

    private Producer captchaProducer = null;  

    @Autowired

    public void setCaptchaProducer(Producer captchaProducer) {

        this.captchaProducer = captchaProducer;

    }  

    @RequestMapping("captcha-image")

    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {  

        response.setDateHeader("Expires", 0);

        // Set standard HTTP/1.1 no-cache headers.

        response.setHeader("Cache-Control", "no-store, no-cache, must-revalidate");

        // Set IE extended HTTP/1.1 no-cache headers (use addHeader).

        response.addHeader("Cache-Control", "post-check=0, pre-check=0");

        // Set standard HTTP/1.0 no-cache header.

        response.setHeader("Pragma", "no-cache");

        // return a jpeg

        response.setContentType("image/jpeg");

        // create the text for the image

        String capText = captchaProducer.createText();

        // store the text in the session

        request.getSession().setAttribute(Constants.KAPTCHA_SESSION_KEY, capText);

        // create the image with the text

        BufferedImage bi = captchaProducer.createImage(capText);

        ServletOutputStream out = response.getOutputStream();

        // write the data out

        ImageIO.write(bi, "jpg", out);

        try {

            out.flush();

        } finally {

            out.close();

        }

        return null;

    }  

}

5、控制类获取当前验证码。

String kaptchaExpected = (String) request.getSession().getAttribute(com.google.code.kaptcha.Constants.KAPTCHA_SESSION_KEY);

效果如图：
