var op={}

//    op.page_id=
    op.page_url=window.location.pathname.replace("/","");
    op.type="删除";
    op.description='用户删除电网'+'"'+selRows[0].gridName+'"';

ajax传递数据类型,转换成json字符串

data:{userName:'admin',workSpaceId:'403',ids:JSON.stringify(ids),op:JSON.stringify(op)},

后台String接受

public JSONObject deleteGridInfo(HttpServletRequest request, String ids, String op){


下面在转换成字符串

Object p = JSON.parse(op);

Operate 为实体类对象

Operate webCaseInfo = JSONArray.parseObject(p.toString(), Operate.class);//实体类接受数据
上面强制转换为实体类对象
