### json 数据源

```xml
<bean name="DemoType2" >
	<var name="x4" type="int" convert="DemoEnum"/>
	<var name="x1" type="bool"/>
	<var name="x5" type="long" convert="DemoEnum"/>
	<var name="x6" type="float"/>
	<var name="x7" type="double"/>
	<var name="x10" type="string"/>
	<var name="x12" type="DemoType1"/>
	<var name="x13" type="DemoEnum"/>
	<var name="x14" type="DemoDynamic" sep=","/>多态数据结构
	<var name="v2" type="vector2"/>
	<var name="v3" type="vector3"/>
	<var name="v4" type="vector4"/>
	<var name="t1" type="datetime"/>
	<var name="k1" type="array,int"/> 使用;来分隔
	<var name="k2" type="list,int"/>
	<var name="k8" type="map,int,int"/>
	<var name="k9" type="list,DemoE2" sep="," index="y1"/>
	<var name="k15" type="array,DemoDynamic" sep=","/> 
</bean>

<table name="TbDataFromJson" value="DemoType2" input="test/json_datas"/>
```

递归遍历test/json_datas整个目录树，**按文件名排序后**依次将每个json数据当作一个记录读入。其中1.json文件内容如下

```json
 {
	"x1":true,
	"x2":3,
	"x3":128,
	"x4":1,
	"x5":11223344,
	"x6":1.2,
	"x7":1.23432,
	"x10":"hq",
	"x12": { "x1":10},
	"x13":"B",
	"x14":{"__type__": "DemoD2", "x1":1, "x2":2},
	"v2":{"x":1, "y":2},
	"v3":{"x":1.1, "y":2.2, "z":3.4},
	"v4":{"x":10.1, "y":11.2, "z":12.3, "w":13.4},
	"t1":"1970-01-01 00:00:00",
	"k1":[1,2],
	"k2":[2,3],
	"k7":[2,3],
	"k8":[[2,2],[4,10]],
	"k9":[{"y1":1, "y2":true},{"y1":2, "y2":false}],
	"k15":[{"__type__": "DemoD2", "x1":1, "x2":2}]
 }
```
