1、List集合的數據的封裝
頁面:
<h1>批量插入商品</h1>
<form action="${ pageContext.request.contextPath }/product1Action.action"method="post">
商品名稱:<input type="text" name="list[0].name"><br/>
商品價格:<input type="text" name="list[0].price"><br/>
商品名稱:<input type="text" name="list[1].name"><br/>
商品價格:<input type="text" name="list[1].price"><br/>
商品名稱:<input type="text" name="list[2].name"><br/>
商品價格:<input type="text" name="list[2].price"><br/>
<inputtype="submit"value="批量導入">
</form>
Action:
/**
* Struts2複雜數據類型的封裝:封裝到List集合中
*
*/
public class Product1Action extends ActionSupport{
private List<Product> list;
public List<Product> getList() {
returnlist;
}
publicvoid setList(List<Product> list) {
this.list = list;
}
@Override
public String execute() throws Exception {
for (Product product : list) {
System.out.println(product);
}
return NONE;
}
}
2、Map集合的數據的封裝
頁面
<h1>批量插入商品:封裝到Map集合</h1>
<form action="${ pageContext.request.contextPath }/product2Action.action"method="post">
商品名稱:<input type="text" name="map['one'].name"><br/>
商品價格:<input type="text" name="map['one'].price"><br/>
商品名稱:<input type="text" name="map['two'].name"><br/>
商品價格:<input type="text" name="map['two'].price"><br/>
商品名稱:<input type="text" name="map['three'].name"><br/>
商品價格:<input type="text" name="map['three'].price"><br/>
<inputtype="submit"value="批量導入">
</form>
Action:
/**
* Struts2的複雜數據的封裝:Map集合的封裝
* @author lwt

*/
public class Product2Action extends ActionSupport{
private Map<String,Product> map;
public Map<String, Product> getMap() {
return map;
}
public void setMap(Map<String, Product> map) {
this.map = map;
}
@Override
public String execute() throws Exception {
for (String key : map.keySet()) {
Product product = map.get(key);
System.out.println(key+" "+product);
}
return NONE;
}
}
