SpringBoot集成kaptcha驗證碼

本文實例為大家分享了SpringBoot集成kaptcha驗證碼的具體代碼，供大家參考，具體內容如下

1.kaptcha相關介紹

Kaptcha是一個基於SimpleCaptcha的驗證碼開源項目。

2.集成方案

①pom.xml中配置依賴

<!-- 驗證碼--><dependency> <groupId>com.github.penggle</groupId> <artifactId>kaptcha</artifactId> <version>2.3.2</version></dependency>

②配置驗證碼Kaptcha相關設置

@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", "宋體,楷體,微軟雅黑"); Config config=new Config(properties); defaultKaptcha.setConfig(config); return defaultKaptcha; }}

或者

在resources下創建myKaptcher.xml文件

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="captchaProducer"> <property name="config"> <bean> <constructor-arg type="java.util.Properties"> <props> <prop key = "kaptcha.border ">yes</prop> <prop key="kaptcha.border.color">105,179,90</prop> <prop key="kaptcha.textproducer.font.color">blue</prop> <prop key="kaptcha.image.width">100</prop> <prop key="kaptcha.image.height">50</prop> <prop key="kaptcha.textproducer.font.size">27</prop> <prop key="kaptcha.session.key">code</prop> <prop key="kaptcha.textproducer.char.length">4</prop> <prop key="kaptcha.textproducer.font.names">宋體,楷體,微軟雅黑</prop> <prop key="kaptcha.textproducer.char.string">23456789ABCEFGHJKMNOPQRSTUVWXYZ</prop> <prop key="kaptcha.obscurificator.impl">com.google.code.kaptcha.impl.WaterRipple</prop> <prop key="kaptcha.noise.color">black</prop> <prop key="kaptcha.noise.impl">com.google.code.kaptcha.impl.NoNoise</prop> <!--<prop key="kaptcha.noise.impl">com.google.code.kaptcha.impl.DefaultNoise</prop>--> <prop key="kaptcha.background.clear.from">185,56,213</prop> <prop key="kaptcha.background.clear.to">white</prop> <prop key="kaptcha.textproducer.char.space">3</prop> </props> </constructor-arg> </bean> </property> </bean></beans>

然後在啟動類Application中加載配置

@EnableTransactionManagement// 啟動註解事務管理，等同於xml配置方式的<tx:annotation-driven />@SpringBootApplication@EnableScheduling//啟動註解定時任務@MapperScan(basePackages = "com.shawn.mapper")@ImportResource(locations={"classpath:mykaptcha.xml"})public class Application extends SpringBootServletInitializer { public static void main(String[] args) throws Exception { SpringApplication.run(Application.class, args); }}

兩種配置方式在springboot中均可；

③KaptchaController

 @CommonsLog@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); //將驗證碼存到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(); } }}
