ajax得到servlet数据,如何通过servlet中的ajax获取数据？

我想将页面上的一些数据发送到servlet

所以我写了下面的jQuery来做到这一点

我使用所有数据构建一个json字符串，并将其直接发送到servlet

但是我不知道如何从servlet中的ajax获取全部数据

$("#save").click

(

function()

{

$.ajax

(

{

url:'/WebApplication1/Controller',

data:'{"name":"abc","address":"cde"}',

type:'post',

cache:false,

success:function(data){alert(data);},

error:function(){alert('error');}

}

);

}

);

如果查看来自chrome的请求标头的Form Data段

您会看到整个json字符串是关键。
