bootstrap,validator,注册校验,登录错误提示使用BootstrapValidator进行注册校验和登录错误提示，具体内容如下
1、介绍 在AdminEAP框架中，使用了BootstrapValidator校验框架，本文以注册校验的用户名、登录名、密码、确认密码的校验（后面还有时间区间、服务器校验）为例，讲述BootstrapValidator的使用。同时以登录错误提示为例，说明如何在动态改变组件的错误提示信息。 先看下面的注册与登录的校验效果图： 注册校验： 
登录错误提示：根据不同的错误类型，动态改变组件的样式和错误提示内容
2、注册校验 1、头部引入bootstrap-validator.css <link rel="stylesheet" href="${basePath}/resources/adminlte/plugins/bootstrap-validator/dist/css/bootstrap-validator.css" rel="external nofollow" />
${basePath}为系统的路径变量 2、form组件 <form action="${basePath}/oauth/register" method="post" id="register-form"> <input type="hidden" name="oAuthId" value="${oAuthInfo.oAuthId?default('-1')}"> <input type="hidden" name="oAuthType" value="${oAuthInfo.oAuthType?default('-1')}"> <div class="form-group has-feedback"> <input type="text" class="form-control" name="userName" id="userName" placeholder="请输入用户名" required> <span class="glyphicon glyphicon-user form-control-feedback"></span> </div> <div class="form-group has-feedback"> <input type="text" class="form-control" name="loginName" id="loginName" placeholder="请输入登录邮箱/登录名"> <span class="glyphicon glyphicon-envelope form-control-feedback"></span> </div> <div class="form-group has-feedback"> <input type="password" class="form-control" name="password" id="password" placeholder="请输入密码"> <span class="glyphicon glyphicon-lock form-control-feedback"></span> </div> <div class="form-group has-feedback"> <input type="password" class="form-control" name="repassword" id="repassword" placeholder="再次确认密码"> <span class="glyphicon glyphicon-log-in form-control-feedback"></span> </div> <div class="row"> <div class="col-xs-12"> <div class="checkbox icheck"> <label> <input type="checkbox" name="rememberMe" required> 同意遵循<a href="#" rel="external nofollow" >AdminEAP协议</a> </label> </div> </div> <!-- /.col --> </div> <div class="row"> <div class="col-xs-12"> <button type="submit" class="btn btn-danger btn-block btn-flat">注 册</button> </div> </div> </form>3、引入bootstrap-validator.js <script src="${basePath}/resources/adminlte/bootstrap/js/bootstrap.min.js"></script>4、校验的核心js代码 <script> $(function () { //将checkbox渲染为icheck样式 $('input').iCheck({ checkboxClass: 'icheckbox_square-red', radioClass: 'iradio_square-red', increaseArea: '20%' // optional }); //此处为校验的核心代码 $("#register-form").bootstrapValidator({ submitHandler: function (valiadtor, loginForm, submitButton) { valiadtor.defaultSubmit(); }, fields: { userName: { validators: { notEmpty: { message: '用户名不能为空' }, stringLength: { /*长度提示*/ min: 4, max: 30, message: '用户名长度必须在4到30之间' } } }, loginName: { validators: { notEmpty: { message: '登录邮箱名或用户名不能为空' }, stringLength: { /*长度提示*/ min: 4, max: 30, message: '用户名长度必须在4到30之间' }, threshold: 4,//只有4个字符以上才发送ajax请求 remote: { url: "${basePath}/oauth/checkUnique", data: function (validator) { return { loginName: $("#loginName").val(), userId: null }; }, message: '该登录名已被使用，请使用其他登录名', delay:2000 } } }, password: { validators: { notEmpty: { message: '密码不能为空' }, stringLength: { /*长度提示*/ min: 6, max: 30, message: '密码长度必须在6到30之间' }, different: {//不能和用户名相同 field: 'loginName',//需要进行比较的input name值 message: '不能和用户名相同' }, regexp: { regexp: /^[a-zA-Z0-9_/.]+$/, message: '密码由数字字母下划线和.组成' } } }, repassword: { message: '密码无效', validators: { notEmpty: { message: '密码不能为空' }, stringLength: { min: 6, max: 30, message: '用户名长度必须在6到30之间' }, identical: {//相同 field: 'password', message: '两次密码不一致' }, different: {//不能和用户名相同 field: 'loginName', message: '不能和用户名相同' }, regexp: {//匹配规则 regexp: /^[a-zA-Z0-9_/.]+$/, message: '密码由数字字母下划线和.组成' } } } } }); });5、登录名唯一性校验的后台代码 /** * 校验当前登录名/邮箱的唯一性 * @param loginName 登录名 * @param userId 用户ID（用户已经存在，即又改回原来的名字还是唯一的） * @return */ @RequestMapping(value = "/oauth/checkUnique", method = RequestMethod.POST) @ResponseBody public Map checkExist(String loginName, String userId) { Map<String, Boolean> map = new HashMap<String, Boolean>(); User user = userService.getUserByLoginName(loginName); //用户不存在，校验有效 if (user == null) { map.put("valid", true); } else { //用户存在（存在的用户是当前用户，登录名一致，校验通过，否则校验不通过） if(!StrUtil.isEmpty(userId)&&userId.equals(user.getLoginName())){ map.put("valid",true); }else { map.put("valid", false); } } return map; }以上的配置完成了注册文本框的各种校验，更多的校验内容，可以查看相关的bootstrap-validator的API文档。 3、登录错误动态提示 1、在后台登录时，会抛出各种登录不成功的提示，需要动态改变前端组件的错误提示信息。不同类型的错误信息编码，要控制不同的组件样式和提示内容。以下是后台抛出的错误类型和错误信息（使用shiro认证）。 try { subject.login(token); //通过认证 if (subject.isAuthenticated()) { Set<String> roles = roleService.getRoleCodeSet(userName); if (!roles.isEmpty()) { subject.getSession().setAttribute("isAuthorized", true); return MAIN_PAGE; } else {//没有授权 msg = "您没有得到相应的授权！"; model.addAttribute("message", new ResultCode("1", msg)); subject.getSession().setAttribute("isAuthorized", false); LOGGER.error(msg); return LOGIN_PAGE; } } else { return LOGIN_PAGE; } //0 未授权 1 账号问题 2 密码错误 3 账号密码错误 } catch (IncorrectCredentialsException e) { msg = "登录密码错误. Password for account " + token.getPrincipal() + " was incorrect"; model.addAttribute("message", new ResultCode("2", msg)); LOGGER.error(msg); } catch (ExcessiveAttemptsException e) { msg = "登录失败次数过多"; model.addAttribute("message", new ResultCode("3", msg)); LOGGER.error(msg); } catch (LockedAccountException e) { msg = "帐号已被锁定. The account for username " + token.getPrincipal() + " was locked."; model.addAttribute("message", new ResultCode("1", msg)); LOGGER.error(msg); } catch (DisabledAccountException e) { msg = "帐号已被禁用. The account for username " + token.getPrincipal() + " was disabled."; model.addAttribute("message", new ResultCode("1", msg)); LOGGER.error(msg); } catch (ExpiredCredentialsException e) { msg = "帐号已过期. the account for username " + token.getPrincipal() + " was expired."; model.addAttribute("message", new ResultCode("1", msg)); LOGGER.error(msg); } catch (UnknownAccountException e) { msg = "帐号不存在. There is no user with username of " + token.getPrincipal(); model.addAttribute("message", new ResultCode("1", msg)); LOGGER.error(msg); } catch (UnauthorizedException e) { msg = "您没有得到相应的授权！" + e.getMessage(); model.addAttribute("message", new ResultCode("1", msg)); LOGGER.error(msg); }2、前端核心JS代码 <script> $(function () { $('input').iCheck({ checkboxClass: 'icheckbox_square-red', radioClass: 'iradio_square-red', increaseArea: '20%' // optional }); fillbackLoginForm(); $("#login-form").bootstrapValidator({ message:'请输入用户名/密码', submitHandler:function (valiadtor,loginForm,submitButton) { rememberMe($("input[name='rememberMe']").is(":checked")); valiadtor.defaultSubmit(); }, fields:{ userName:{ validators:{ notEmpty:{ message:'登录邮箱名或用户名不能为空' } } }, password:{ validators:{ notEmpty:{ message:'密码不能为空' } } } } }); <!--freemark语法，查看是否从后台传送过来错误信息，并初始化错误提示组件LoginValidator--> <#if message??> new LoginValidator({ code:"${message.code?default('-1')}", message:"${message.message?default('')}", userName:'userName', password:'password' }); </#if> }); //使用本地缓存记住用户名密码 function rememberMe(rm_flag){ //remember me if(rm_flag){ localStorage.userName=$("input[name='userName']").val(); localStorage.password=$("input[name='password']").val(); localStorage.rememberMe=1; } //delete remember msg else{ localStorage.userName=null; localStorage.password=null; localStorage.rememberMe=0; } } //记住回填 function fillbackLoginForm(){ if(localStorage.rememberMe&&localStorage.rememberMe=="1"){ $("input[name='userName']").val(localStorage.userName); $("input[name='password']").val(localStorage.password); $("input[name='rememberMe']").iCheck('check'); $("input[name='rememberMe']").iCheck('update'); } } </script>3、LoginValidator组件的代码 login.js /** * Created by billJiang on 2017/1/12. * 登录异常信息显示 */function LoginValidator(config) { this.code = config.code; this.message = config.message; this.userName = config.userName; this.password = config.password; this.initValidator();}//0 未授权 1 账号问题 2 密码错误 3 账号密码错误LoginValidator.prototype.initValidator = function () { if (!this.code) return; if(this.code==0){ this.addPasswordErrorMsg(); }else if(this.code==1){ this.addUserNameErrorStyle(); this.addUserNameErrorMsg(); }else if(this.code==2){ this.addPasswordErrorStyle(); this.addPasswordErrorMsg(); }else if(this.code==3){ this.addUserNameErrorStyle(); this.addPasswordErrorStyle(); this.addPasswordErrorMsg(); } return;}LoginValidator.prototype.addUserNameErrorStyle = function () { this.addErrorStyle(this.userName);}LoginValidator.prototype.addPasswordErrorStyle = function () { this.addErrorStyle(this.password);}LoginValidator.prototype.addUserNameErrorMsg = function () { this.addErrorMsg(this.userName);}LoginValidator.prototype.addPasswordErrorMsg = function () { this.addErrorMsg(this.password);}LoginValidator.prototype.addErrorMsg=function(field){ $("input[name='"+field+"']").parent().append('<small data-bv-validator="notEmpty" data-bv-validator-for="'+field+'" class="help-block">' + this.message + '</small>');}LoginValidator.prototype.addErrorStyle=function(field){ $("input[name='" + field + "']").parent().addClass("has-error");}以上把错误提示封装成了一个LoginValidator组件，方便前端调用，增强代码的可维护性，因为没有找到Bootstrap-validator改变错误提示的接口，所以查看了源码之后做了封装。 4、补充 1、时间区间校验 "startTime":{ validators:{ date:{ format:'YYYY-MM-DD HH:mm', message:'日期格式不正确' }, callback:{ callback:function(value,validator){ var startTime=value; var endTime=$("#endTime").val(); if(startTime&&endTime){ return DateDiff(endTime,startTime)>0; }else{ return true; } }, message:'结束时间不能小于开始时间' } } }, "endTime":{ validators:{ date:{ format:'YYYY-MM-DD HH:mm', message:'日期格式不正确' }, callback:{ callback:function(value,validator){ var startTime=$("#startTime").val(); var endTime=value; if(startTime&&endTime){ return DateDiff(endTime,startTime)>0; }else{ return true; } }, message:'结束时间不能小于开始时间' } } },2、服务器校验 "jobClass": { validators: { notEmpty: {message: '执行类名不能为空'}, remote:{ url:basePath+"/job/checkJobClass", data: function(validator) { return { jobClass:$('#jobClass').val(), }; }, message:'该执行类不存在' } } }后台代码 @RequestMapping(value="/checkJobClass",method = RequestMethod.POST) @ResponseBody public Map checkJobClass(String jobClass){ Map map=new HashMap<>(); try { Class<?> objClass = Class.forName(jobClass); if(objClass!=null) map.put("valid", true); return map; } catch (Exception ex) { logger.error(ex.getMessage().toString()); map.put("valid", false); return map; } }Github： https://github.com/bill1012
