Struts中实体类的字段名称要对应jsp中textfield中name属性值

例子：private String id;
private String firstName;
private String middleInitial;
private String lastName;
private String street;
private String city;
private String state;
private String zip;
private String phone;
private String email;
   和下面的jsp文件中的 name的值要一样

<tr><td><s:textfield name="id" label="编号"></s:textfield></td></tr>
<tr><td><s:textfield name="firstName" label="客户姓"></s:textfield></td></tr>
<tr><td><s:textfield maxlenght="1" name="middleInitial" label="中间缩写"></s:textfield></td></tr>
<tr><td><s:textfield name="lastName" label="客户名"></s:textfield></td></tr>
<tr><td><s:textfield name="street" label="街道"></s:textfield></td></tr>
<tr><td><s:textfield name="city" label="城市"></s:textfield></td></tr>
<tr><td><s:textfield maxlenght="2" name="state" label="省份简写"></s:textfield></td></tr>
<tr><td><s:textfield name="zip" label="区号"></s:textfield></td></tr>
<tr><td><s:textfield name="phone" label="电话"></s:textfield></td></tr>
<tr><td><s:textfield name="email" label="Email"></s:textfield></td></tr>
