Spring shiro + bootstrap + jquery.validate 实现登录、注册功能
小爷胡汉三 人气:0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！
其中还使用到啦jquery-confirm.js，这是一个弹出框的插件：点击查看
