springboot springsecurity怎么实现图片验证码登录-亚博电竞手机版

后端代码:

获取验证码,将结果放到session里

packagecom.liruilong.hros.controller;importcom.liruilong.hros.model.respbean;importorg.springframework.web.bind.annotation.getmapping;importorg.springframework.web.bind.annotation.restcontroller;importcom.wf.captcha.arithmeticcaptcha;importjavax.servlet.http.httpservletrequest;importjavax.servlet.http.httpservletresponse;importjava.util.hashmap;importjava.util.map;/***@description:*@author:liruilong*@date:2019/12/1919:58*/@restcontrollerpublicclasslogincontroller{@getmapping(value="/auth/code")publicmapgetcode(httpservletrequestrequest,httpservletresponseresponse){//算术类型https://gitee.com/whvse/easycaptchaarithmeticcaptchacaptcha=newarithmeticcaptcha(111,36);//几位数运算，默认是两位captcha.setlen(2);//获取运算的结果stringresult=captcha.text();system.err.println("生成的验证码：" result);//保存//验证码信息mapimgresult=newhashmap(2){{put("img",captcha.tobase64());}};request.getsession().setattribute("yanzhengma",result);returnimgresult;}}

定义一个verifycodefilter过滤器

packagecom.liruilong.hros.filter;importcom.liruilong.hros.exception.validatecodeexception;importcom.liruilong.hros.config.myauthenticationfailurehandler;importorg.apache.commons.lang3.stringutils;importorg.springframework.beans.factory.annotation.autowired;importorg.springframework.context.annotation.bean;importorg.springframework.security.core.authenticationexception;importorg.springframework.stereotype.component;importorg.springframework.web.filter.onceperrequestfilter;importjavax.servlet.filterchain;importjavax.servlet.servletexception;importjavax.servlet.http.httpservletrequest;importjavax.servlet.http.httpservletresponse;importjava.io.ioexception;/***@description:*@author:liruilong*@date:2020/2/719:39*/@componentpublicclassverifycodefilterextendsonceperrequestfilter{@beanpublicverifycodefiltergetverifycodefilter(){returnnewverifycodefilter();}@autowiredmyauthenticationfailurehandlermyauthenticationfailurehandler;@overrideprotectedvoiddofilterinternal(httpservletrequestrequest,httpservletresponseresponse,filterchainfilterchain)throwsservletexception,ioexception{if(stringutils.equals("/dologin",request.getrequesturi())&&stringutils.equalsignorecase(request.getmethod(),"post")){//1.进行验证码的校验try{stringrequestcaptcha=request.getparameter("code");if(requestcaptcha==null){thrownewvalidatecodeexception("验证码不存在");}stringcode=(string)request.getsession().getattribute("yanzhengma");if(stringutils.isblank(code)){thrownewvalidatecodeexception("验证码过期！");}code=code.equals("0.0")?"0":code;logger.info("开始校验验证码，生成的验证码为：" code "，输入的验证码为：" requestcaptcha);if(!stringutils.equals(code,requestcaptcha)){thrownewvalidatecodeexception("验证码不匹配");}}catch(authenticationexceptione){//2.捕获步骤1中校验出现异常，交给失败处理类进行进行处理myauthenticationfailurehandler.onauthenticationfailure(request,response,e);}finally{filterchain.dofilter(request,response);}}else{filterchain.dofilter(request,response);}}}

定义一个自定义异常处理，继承authenticationexception

packagecom.liruilong.hros.exception;importorg.springframework.security.core.authenticationexception;/***@description:*@author:liruilong*@date:2020/2/87:24*/publicclassvalidatecodeexceptionextendsauthenticationexception{publicvalidatecodeexception(stringmsg){super(msg);}}

security配置.

在之前的基础上加filter的基础上加了

http.addfilterbefore(verifycodefilter, usernamepasswordauthenticationfilter.class)，验证处理上，验证码和表单验证失败用同一个失败处理器，
