Spring shiro bootstrap jquery.validate 登录、注册功能的实现方法

程序员文章站 2022-04-21 13:01:44
...
本文主要介绍了Spring shiro + bootstrap + jquery.validate 实现登录、注册功能,需要的朋友可以参考下,希望能帮助到大家。

之前的文章中我们已经搭建好框架,并且设计好了,数据库。

现在我们开始实现登录功能,这个可以说是Web应用最最最普遍的功能了。

先来说说我们登录的逻辑:

输入用户名、密码(validate进行前端验证)——ajax调用后台action方法——根据用户名调用业务层到数据层查询数据库信息——查询的密码跟用户输入的密码比对——shiro登录身份验证——将用户信息存入session——响应前端——前端跳转

这个是我要告诉大家的姿势,还有很多很多的姿势。下面我们来看具体的代码。

首先前端验证,这里使用了jquery.validate来进行验证,jquery.validate的使用很简单,这里我们说说存js的方式:

$().ready(function() { 
 /**登录验证**/ 
 $("#login_form").validate({ 
  rules: { 
   loginAccount: "required", 
   loginPass: { 
    required: true, 
    minlength: 5 
   }, 
  }, 
  messages: { 
   loginAccount: "请输入姓名", 
   loginPass: { 
    required: "请输入密码", 
    minlength: jQuery.format("密码不能小于{0}个字 符") 
   }, 
  }, 
  submitHandler:function(form){ 
   $.ajax({ 
    dataType : "json", 
    url : "sysuser/login.action", 
    type : "post", 
    data : $("#login_form").serialize(), 
    success : function(data) { 
     $.alert(data.message); 
     if(data.success){ 
      window.location.href = 'page/main.action'; 
     } 
    }, 
    error : function (e){ 
     var d = e.responseJSON; 
     if(d){ 
      $.alert(d.message); 
     } 
    } 
   }); 
   return false; //阻止form提交 
  } 
 }); 
 /**注册验证**/ 
 $("#register_form").validate({ 
  rules: { 
   loginAccount:{ 
    required:true, 
    remote: { 
     url: "sysuser/getUserNameCount.action", 
     type: "post", 
     dataType: "json", 
     data: { 
      loginAccount: function () { 
       return $("#register_account").val(); 
      } 
     }, 
     dataFilter: function (data) {    //判断控制器返回的内容 
      data = jQuery.parseJSON(data); 
      return data.success; 
     } 
    } 
   }, 
   loginPass: { 
    required: true, 
    minlength: 5, 
    maxlength:20 
   }, 
   rloginPass: { 
    equalTo: "#register_password" 
   }, 
   userEmail: { 
    required: true, 
    email: true, 
    remote: { 
     url: "sysuser/getEMailCount.action", 
     type: "post", 
     dataType: "json", 
     data: { 
      email: function () { 
       return $("#register_email").val(); 
      } 
     }, 
     dataFilter: function (data) {    //判断控制器返回的内容 
      data = jQuery.parseJSON(data); 
      return data.success; 
     } 
    } 
   } 
  }, 
  messages: { 
   loginAccount:{ 
    required: "请输入姓名", 
    remote: "用户名已存在" 
   }, 
   loginPass: { 
    required: "请输入密码", 
    minlength: jQuery.format("密码不能小于{0}个字 符"), 
    maxlength: jQuery.format("密码不能大于{0}个字 符"), 
   }, 
   rloginPass: { 
    required: "请输入确认密码", 
    equalTo: "两次密码不一样" 
   }, 
   userEmail: { 
    required: "请输入邮箱", 
    email: "请输入有效邮箱", 
    remote: "邮箱已存在" 
   } 
  }, 
  submitHandler:function(form){ 
   $.ajax({ 
    dataType : "json", 
    url : "sysuser/register.action", 
    type : "post", 
    data : $("#register_form").serialize(), 
    success : function(data) { 
     $.alert(data.message); 
     if(data.success){ 
      window.location.href = 'page/main.action'; 
     } 
    }, 
    error : function (e){ 
     var d = e.responseJSON; 
     if(d){ 
      $.alert(d.message); 
     } 
    } 
   }); 
   return false; //阻止form提交 
  } 
 }); 
 /**隐藏显示登录注册**/ 
 $("#register_btn").click(function() { 
  $("#register_form").css("display", "block"); 
  $("#login_form").css("display", "none"); 
 }); 
 $("#back_btn").click(function() { 
  $("#register_form").css("display", "none"); 
  $("#login_form").css("display", "block"); 
 }); 
});

在$("#login_form").validate({...})方法中,login_form为你要验证的form的id;rules为要验证的字段;messages为要提示的内容,如果不填写,则会提示默认信息;submitHandler为点击提交(submit)按钮后的回调方法,这里面最后的return false是为了阻止form表单的提交,因为我这里要用ajax的方式提交;在注册中的loginAccount字段有一个属性remote这个是为了做ajax验证的,在没有提交表单之前,我们就验证用户输入的用户名是否在系统中已经存在。

我们在编程总,发现总是会有那么几个方法在相同的代码层总用到,比如在控制层中获取用户session,或者输出响应信息等;在dao层中调用Hibernate的save方法,update方法,delete方法等。所以我们应该在框架搭建的初期去建立一些通用的工具类或者是Base方法,下面我们新建BaseController方法,并且让后面的控制器都来继承它。

至此,登录跟注册就OK啦!
