SpringBoot整合kaptcha实现验证码功能

目录

一、引入依赖

二、编写配置类

三、编写接口

四、测试

一、引入依赖

<!--kaptcha依赖包--> <dependency> <groupId>com.baomidou</groupId> <artifactId>kaptcha-spring-boot-starter</artifactId> <version>1.1.0</version> </dependency>

二、编写配置类

package net.xdclass.config; import com.google.code.kaptcha.Constants; import com.google.code.kaptcha.impl.DefaultKaptcha; import com.google.code.kaptcha.util.Config; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import java.util.Properties; @Configuration public class CaptchaConfig { /** * 验证码配置 * Kaptcha配置类名 * * @return */ @Bean @Qualifier("captchaProducer") public DefaultKaptcha kaptcha() { DefaultKaptcha kaptcha = new DefaultKaptcha(); Properties properties = new Properties(); // properties.setProperty(Constants.KAPTCHA_BORDER, "yes"); // properties.setProperty(Constants.KAPTCHA_BORDER_COLOR, "220,220,220"); // //properties.setProperty(Constants.KAPTCHA_TEXTPRODUCER_FONT_COLOR, "38,29,12"); // properties.setProperty(Constants.KAPTCHA_IMAGE_WIDTH, "147"); // properties.setProperty(Constants.KAPTCHA_IMAGE_HEIGHT, "34"); // properties.setProperty(Constants.KAPTCHA_TEXTPRODUCER_FONT_SIZE, "25"); // //properties.setProperty(Constants.KAPTCHA_SESSION_KEY, "code"); //验证码个数 properties.setProperty(Constants.KAPTCHA_TEXTPRODUCER_CHAR_LENGTH, "4"); // properties.setProperty(Constants.KAPTCHA_TEXTPRODUCER_FONT_NAMES, "Courier"); //字体间隔 properties.setProperty(Constants.KAPTCHA_TEXTPRODUCER_CHAR_SPACE,"8"); //干扰线颜色 // properties.setProperty(Constants.KAPTCHA_NOISE_COLOR, "white"); //干扰实现类 properties.setProperty(Constants.KAPTCHA_NOISE_IMPL, "com.google.code.kaptcha.impl.NoNoise"); //图片样式 properties.setProperty(Constants.KAPTCHA_OBSCURIFICATOR_IMPL, "com.google.code.kaptcha.impl.WaterRipple"); //文字来源 properties.setProperty(Constants.KAPTCHA_TEXTPRODUCER_CHAR_STRING, "0123456789"); Config config = new Config(properties); kaptcha.setConfig(config); return kaptcha; } }

三、编写接口

package net.xdclass.controller; import com.google.code.kaptcha.Producer; import lombok.extern.slf4j.Slf4j; import net.xdclass.service.NotifyService; import net.xdclass.util.JsonData; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; import javax.imageio.ImageIO; import javax.servlet.ServletOutputStream; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.awt.image.BufferedImage; import java.io.IOException; @RestController @RequestMapping("/api/account/v1") @Slf4j public class NotifyController { @Autowired private NotifyService notifyService; @Autowired private Producer captchaProducer; @RequestMapping("send_code") public JsonData sendCode() { notifyService.testSend(); return JsonData.buildSuccess(); } /** * 生成验证码 * @param request * @param response */ @GetMapping("captcha") public void getCaptcha(HttpServletRequest request, HttpServletResponse response){ String captchaText = captchaProducer.createText(); log.info("验证码内容:{}",captchaText); //存储redis,配置过期时间 ， jedis/lettuce //redisTemplate.opsForValue().set(getCaptchaKey(request),captchaText,CAPTCHA_CODE_EXPIRED,TimeUnit.MILLISECONDS); BufferedImage bufferedImage = captchaProducer.createImage(captchaText); try (ServletOutputStream outputStream = response.getOutputStream()){ ImageIO.write(bufferedImage,"jpg",outputStream); outputStream.flush(); } catch (IOException e) { log.error("获取流出错:{}",e.getMessage()); } } }

四、测试
