SpringBoot集成kaptcha验证码

SpringBoot集成kaptcha验证码

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

com.github.penggle

kaptcha

2.3.2

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

xmlns:xsi="http://w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://springframework.org/schema/beans http://springframework.org/schema/beans/spring-beans.xsd">

yes

105,179,90

blue

100

50

27

code

4

宋体,楷体,微软雅黑

black

com.google.code.kaptcha.impl.NoNoise

185,56,213

white

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

@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("http:///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();

}

}

}
