使用google的gson转换，在线验证可用，例子来自saiku-foodmart。
PS：此文档是倒着写的，所以应先看2再看1…
1.首先是cube和共享维度：
PS：相关代码在com.xxx.schema包下
以Cube：Sales 2为例，此cube包含以上内容，每个cube封装为一条JSON
完整版见 附录2。
格式化后的(节选)：
{
"cubeName": "Sales 2",
"cuniqueName": "[Sales 2]",
"ccaption": "Sales 2", //此三项的含义同2中的注释
"dimensions": [ //此cube中包含的维度
{
"dimenName": "Time",
"duniqueName": "[Time]",
"dcaption": "Time", //名字属性都是这三个
"hierarchies": [ //此维度中的hierarchy
{
"HierarchyName": "Time",
"huniqueName": "[Time]",
"hcaption": "Time",
"levels": [ //此hierarchy中的level
{
"levelName": "Year",
"luniqueName": "Year",
"lcaption": "Year",
"depth": 0
//depth：level的深度，数值越小范围越大，如0表示ALL
}
……
]
},
{
"HierarchyName": "Time.Weekly",
……
}
]
}
……
],
"measures": [
{
"measureName": "Sales Count",
"muniqueName": "[Measures].[Sales Count]",
"mcaption": "Sales Count"
}
……
]
}
共享维度的结构与此类似，demo版应该用不到，示例见 附录3。
PS：生成MDX语句的代码见包com.xxx.mdx，
前端需要传给后台的数据形式，见各类开头的长注释。
2.然后是查询的结果(cell)：
PS：相关代码在com.xxx.result包下
选择Cube：Sales，拖选以下条件：
每行封装一个JSON，完整样例见后面 附录1：
取出第一行的第一个cell，格式化（左上，坐标0,0）
{
"value": "$22,553.64", //这个cell的值
"coordRow": 0, //行坐标
"coordColumn": 0, //列坐标
"columns": [ //列上的表头（可能有多层）
{
"cname": "CA",
"cuniqueName": "[Customers].[USA].[CA]",
"ccaption": "CA"
},
{ //如此处为第二个表头
"cname": "F",
"cuniqueName": "[Gender].[F]",
"ccaption": "F"
}
],
"rows": [ //行上的表头（此例只有一个）
{
"rname": "Profit",
"runiqueName": "[Measures].[Profit]",
"rcaption": "Profit"
}
]
}
其中column、row都有三个属性：
-name：简称，如F
-uniqueName：全称，如[Gender].[F]
-caption：显示在页面中的名字，如“女”，默认与-name相同
