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
@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.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@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); //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(); } }}
以上就是如何在springboot中使用kaptcha实现验证码的详细内容。
