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