[Struts2] 內建的 OGNL Type Converter

jsp

<s:iterator value="values" id="id">
<s:textfield name="values" value="%{id}">
</s:textfield>


action.java

private String values[]={"","",""};

public String[] getValues() {
return values;
}
public void setValues(String s[]){
this.values=s;
}

說明:在java要先宣告出 String[]的大小，然後才能在jsp中順利產生多個textfield input.
不過這樣做法沒辦法動態不同數量的textfield.
