oa_20:

1、创建动态表单的领域模型

FieldInput.java
FieldItem.java
FieldType.java
FlowForm.java
FormField.java
FieldInput.hbm.xml
FieldType.hbm.xml
FlowForm.hbm.xml
FormField.hbm.xml

2、修改hibernate.cfg.xml，把动态表单相关的hbm.xml文件添加上去
3、创建动态表单定义的业务逻辑接口以及实现类
FormManager.java
FormManagerImpl.java

4、修改init_datas.xml和InitSystemDataImpl.java，
   添加动态表单相关数据的初始化代码
  
【请drop掉数据库，并重新创建数据库之后，运行InitSystemDatasTest.java，重新初始化数据】

public class InitSystemDatasTest extends BaseUnitTest {
	private InitSystemDatas initSystemDatas;
	public void testAddOrUpdateInitDatas() {
		initSystemDatas.addOrUpdateInitDatas("init_datas.xml");
		setComplete();
	}
	
	public void setInitSystemDatas(InitSystemDatas initSystemDatas) {
		this.initSystemDatas = initSystemDatas;
	}

}
