  ```DataSqlSource```是```DataSource```的SQL扩展类，增强了对原生SQL的操作。
## SQL模板
  Redkale中的SQL模板与Mybatis里的SQL模板用法类似， 最大区别在于不需要写很多```if/else```判断语句,也不用写xml文件， 框架会根据参数存在与否动态生成sql语句， 查询结果时带下划线的sql字段名和类中的驼峰字段名会自动匹配。

```sql
SELECT * FROM user WHERE user_id IN ${bean.userIds} OR user_name = ${bean.userName}
```
  当bean.userIds=null，bean.userName='hello'时，sql语句转换成
  当bean.userIds=null，bean.userName='hello'时，sql语句转换成:
```sql
SELECT * FROM user WHERE user_name = 'hello'
```
  当bean.userIds=[1,2,3]，bean.userName=null时，sql语句转换成
  当bean.userIds=[1,2,3]，bean.userName=null时，sql语句转换成:
```sql
SELECT * FROM user WHERE user_id IN (1,2,3)
```
  IN或者NOT IN语句当参数不为null而是空数组或者空List会进行特殊处理，IN语句会转化成```1=1```, NOT IN语句会转化成```1=2```。 当bean.userIds=空数组，bean.userName='hello'时，sql语句转换成
