本文实例为大家分享了SpringBoot集成kaptcha验证码的具体代码，供大家参考，具体内容如下

1.kaptcha相关介绍

Kaptcha是一个基于SimpleCaptcha的验证码开源项目。

2.集成方案

①pom.xml中配置依赖

<!-- 验证码--><dependency> <groupId>com.github.penggle</groupId> <artifactId>kaptcha</artifactId> <version>2.3.2</version></dependency>

②配置验证码Kaptcha相关设置

@Configurationpublic class kaptchaConfig { @Bean(name="captchaProducer") public DefaultKaptcha getKaptchaBean(){ DefaultKaptcha defaultKaptcha=new DefaultKaptcha(); Properties properties=new Properties(); properties.setProperty("kaptcha.border", "yes"); properties.setProperty("kaptcha.border.color", "105,179,90"); properties.setProperty("kaptcha.textproducer.font.color", "blue"); properties.setProperty("kaptcha.image.width", "125"); properties.setProperty("kaptcha.image.height", "45"); properties.setProperty("kaptcha.session.key", "code"); properties.setProperty("kaptcha.textproducer.char.length", "4"); properties.setProperty("kaptcha.textproducer.font.names", "宋体,楷体,微软雅黑"); Config config=new Config(properties); defaultKaptcha.setConfig(config); return defaultKaptcha; }}

或者

在resources下创建myKaptcher.xml文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://monsLog@Controllerpublic class KaptchaController extends BaseController { @Autowired private Producer captchaProducer; @GetMapping("/getKaptchaImage") public void getKaptchaImage() 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); //将验证码存到session session.setAttribute(Constants.KAPTCHA_SESSION_KEY, capText); log.info(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(); } }}

3.测试效果
