java反射封装表单请求数据至对象
页面端：
?
提交数据 ?var dates=$("#domainForm").serialize(); 我们会看到，这个值为：
userName=%E7%94%A8%E6%88%B7&skill=java&skill=.net&phone=p1&phone=p2
&hobby=swim&hobby=net&address=addr%26sex%3Dman
?
由此可看出，不管是checkbox，select，或者故意放置多个name相同的input框，传送数据时都是 &变量名A（可能相同多个）=值B 的形式组装，值为addr&sex=man 中的&被转为%26 ，?=转为%3D ?这样规避了提交的值与传递的格式之间的冲突。
?
服务端获取请求的值，并且组装到对象中
