###struts模型驅動能夠封裝 物件型別屬性的屬性 到當前物件.
######(多對一 多的一方)物件屬性 表單項name的取值(請求引數傳值格式):【物件屬性名.物件屬性的屬性值】.
例子:新增聯絡人（有個單物件屬性customer()所屬客戶）
====客戶：字典 是 多對一。也是一樣。 新增客戶，客戶回顯字典，add.jsp也要 填寫 客戶實體類的字典屬性.字典id.
頁面程式碼：###
<tr> <td>所屬客戶：</td> <td colspan="3"> <!-- <input type="text" name="custId" value="1" style="WIDTH: 180px"/> --> <!-- ===模型驅動很強大：會自動把物件屬性的屬性值封裝。 --> <select name="customer.custId" id="cust" style="WIDTH: 180px" type="text"> <!-- <select name="custId" id="cust" style="WIDTH: 180px" type="text"> ===報錯--> </select> </td> </tr>

JAVA -- Struts模型驅動和屬性驅動
1.屬性驅動請求一個action，它會把對應的action中屬性的名稱對應到表單的名稱上，並且呼叫set方法注入2.模型驅動ModelDriver（模型驅動）：它把屬性名稱最終對映成一個User物件。在表單中直接用屬性，而不是物件.屬性的形式，這種方式比較麻煩。它繼承了Mod
