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
@Configuration
public 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://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" class="com.google.code.kaptcha.impl.DefaultKaptcha">
<property name="config">
<bean class="com.google.code.kaptcha.util.Config">
<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">宋体,楷体,微软雅黑</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>
然后在启动类Application中加载配置
@EnableTransactionManagement// 启动注解事务管理，等同于xml配置方式的 <tx:annotation-driven />
@SpringBootApplication
@EnableScheduling//启动注解定时任务
@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);
}
}
两种配置方式在springboot中均可；
③KaptchaController
@CommonsLog
@Controller
public 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();
}
}
}
