1、被调用的Dao接口
public interface IFieldDescriptionDao {
public List<String> getFieldDescription(Connection conn,String tableName)throws SQLException;
}
2、被调用的DaoImpl实现
public class FieldDescriptionDaoImpl implements IFieldDescriptionDao{
public List<String> getFieldDescription(Connection conn,String tableName)throws SQLException{//获取字段的中文说明,作为标题行在页面展示
return fieldsList;
}
}
3、调用的DaoImpl实现
import com.dao.IFieldDescriptionDao;
public class CommunicationStatDaoImpl implements ICommunicationStatDao{
private IFieldDescriptionDao fieldDescriptionDao; //声明另一个Dao字段说明
public List<List<String>> queryCommunicationList(Connection conn, int pageSize, int currPage) throws SQLException {
List<List<String>> list = new ArrayList<List<String>>();
list.add(fieldDescriptionDao.getFieldDescription(conn,"JT_CommunicationStatus"));//调用方法
return list;
}
//要生成Get/Set方法,要不实例对象为空
public IFieldDescriptionDao getFieldDescriptionDao() { //get方法
return fieldDescriptionDao;
}
public void setFieldDescriptionDao(IFieldDescriptionDao fieldDescriptionDao) { //set方法
this.fieldDescriptionDao = fieldDescriptionDao;
}
}
4、在调用的配置文件中,
<bean name="communicationDao" class="com.chatone.dao.CommunicationStatDaoImpl">
<property name="fieldDescriptionDao" ref="fieldDescriptionDao"/> //被调用实例属性
</bean>
