# yaml 数据源


## 以复合数据形式组织

整个表在一个或者多个yaml文件中组织。用法与json数据源相似，参见 [json数据源](./data_json.md)

## 以目录树形式组织

```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="TbDataFromYaml" value="DemoType2" input="test/yaml_datas"/> 
```

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

```yaml

```
