json 字符串包含数组转换为object对象是报异常java.lang.ClassCastException: net.sf.ezmorph.bean.MorphDynaBean cannot be cast to
前台传到后台的json字符串
前台实现这种格式json字符串方式：

10
11
12
|
function contentFun(){
respType = respTypeFun();
return "{\"respType\":\"" + respType + "\",\"content\":\"" + content + "\",\"name\":\"" + name + "\"}";
}
function respTypeFun(){
if(respType == undefined || respType == ""){
respType = "res_ejcd";
return respType;
}
return respType;
}

var tableId = document.getElementById("tableId").getElementsByTagName("div");
for(var i = 0 ; i < choiceNum ; i ++){
if(tableId[i].hasAttribute("reldate")){
var d = eval('('+ tableId[i].getAttribute("reldate") +')');
d.subMenu = [];
var t = i + 1;
var cNode = document.getElementById("zicaidan" + t).getElementsByTagName("div");
for(var j = 0 ; j < cNode.length ; j ++){
if(cNode[j].hasAttribute("reldate")){
d.subMenu[j] = eval('('+ cNode[j].getAttribute("reldate") +')');
}
}
console.info(d);
d = JSON.stringify(d);
console.info(d);
menuStr += d + ",";
}
}
menuStr = "[" +menuStr.substring(0, menuStr.length - 1) + "]";
|
contentFun（）将获取到的数据保存到一个节点中 该节点属性为reldate如下：

<
table
class="caiduannum" style="border: none;width: 255px;" cellpadding="0" cellspacing="0" id="tableId">
<
tbody
>
<
tr
>
<
td
>
<
div
id="maincd1" onclick="menuChoice(this)" class="maincd" style="height: 45px;width: 85px;line-height: 45px;text-align: center; reldate='{"respType":"res_ejcd","content":"aa;dsf;t ;","name":"菜单一"}'> <
span
class="menuSpan" >菜单一</
span
></
div
>
|

</
td
>
<
td
>
<
div
id="maincd2" onclick="menuChoice(this)" class="maincd" style="height: 45px;width: 85px;line-height: 45px;text-align: center;" reldate='{"respType":"res_ejcd","content":"fg ;","name":"菜单二"}' > <
span
class="menuSpan" >菜单二</
span
> </
div
> </
td
> <
td
> </
tr
> </
tbody
> </
table
>
|
通过上面方法即可获取到下面json字符串，将此字符串传给后台
|
1
|
[ { "respType":"res_ejcd", "content":"aa;dsf;t ;", "name":"菜单一", "subMenu":[ { "respType":"res_ejcd", "content":"aa", "name":"菜单一" }, { "respType":"res_gjz", "content":"的风格", "name":"dsf" }, { "respType":"res_ejcd", "content":"t ", "name":"菜单一" } ] }, { "respType":"res_ejcd", "content":"fg ;", "name":"菜单二", "subMenu":[ null, { "respType":"res_url", "content":"http://www.baidu.com", "name":"fg " } ] }]
