[Struts2]一次產生多個textfield

java

private String threeTextfield[]={"","",""};
  
public String[] getThreeTextfield() {
   return threeTextfield;
}

public void setThreeTextfield(String[] threeTextfield) {
   this.threeTextfield = threeTextfield;
}

jsp

<s:iterator value="threeTextfield" status="rowstatus" id="id">
<tr>
   <td><s:textfield name="threeTextfield" value="%{id}" /></td>
</tr>       
</s:iterator>

透過這樣的方式
優點是jsp的撰寫與後端的接收都快了不少
缺點是無法指定textfield的個數
