jquery ajax前台通过json格式往后台传数据后台对象接到的老是null

前台的静态json数据

var resContactInfos1 = [{

metadataId: '001',

orgCode:'001',

orgName: 'zhangsan',

address: '20',

email: 'shanghai'

{

metadataId: '002',

orgCode: '002',

orgName: 'beijing',

address: '21',

email: 'beijing'

}

];

ajax 请求

var data1={resContactInfo:resContactInfos1};

$.ajax({

url: "rc/resourceCatalogManagerAction!saveResource.action", //后台处理的地址

type: "POST",

contentType: "application/json",

data: JSON.stringify(data1),

success:function(){

alert("success");

}

});

后台action

private list<ResContactInfo>resContactInfo;

后台有个resContactInfo属性它的get set方法也写了

ResContactInfo这个类的属性为 metadataId 、orgCode等同上面的json对象中的5个属性

问题：我看到浏览器发的请求感觉是没有问题的但是后台显示接不到值求解？？？

可参考我的博客：http://quarterlifeforjava.iteye.com/blog/2024336
希望能帮到你

[code="java"]
好像ajax请求少个datatype吧

var markers = [{ "position": "128.3657142857143", "markerPosition": "7" },
{ "position": "235.1944023323615", "markerPosition": "19" },
{ "position": "42.5978231292517", "markerPosition": "-3" }];

$.ajax({
type: "POST",
url: "/webservices/PodcastService.asmx/CreateMarkers",
data: JSON.stringify({ Markers: markers }),
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(data){alert(data);},
failure: function(errMsg) {
alert(errMsg);
}
});
[/code]

能把请求头信息截图看一下么？

我怀疑是
var data1={resContactInfo:resContactInfos1};
这一句多余了

[code="java"]$.ajax({

      url: "rc/resourceCatalogManagerAction!saveResource.action", //后台处理的地址

      type: "POST",

      contentType: "application/x-www-form-urlencod",

      data: JSON.stringify(data1),

      success:function(){

     alert("success");

      }

});[/code]

把contentType改一下就可以了

var data1={resContactInfo:resContactInfos1};
改为var data1={"resContactInfo":resContactInfos1};

在ajax中添加dataType: "json"估计就可以了。

可能是你的格式错了：

如：你参考的代码中初始数据后面的值是双引号而你的是单引号

var persons = [{
id: "001",
name: "zhangsan",
age: "20",
gender: true,
city: "shanghai"
},
{
id: "002",
name: "lisi",
age: "21",
gender: false,
city: "beijing"
}
];
