一: struts-config.xml 配置
二: 输入页面�0�2add_traffic_policy.jsp

三: TrafficForm的关键代码
public class TrafficForm extends BaseActionForm implements Serializable {
private static final long serialVersionUID = 454397279205151336L;
private List traffics = new AutoArrayList(Traffic.class);
public List getTraffics() {
return traffics;
}
public void setTraffics(List traffics) {
this.traffics.clear();
this.traffics.addAll(traffics);
}
}
�0�2
四.bean，提问页面省略了get set方法
public class Traffic extends BaseActionForm implements Serializable {
private static final long serialVersionUID = 454397279205151336L;
/**
* Fields
*/
private Integer policyId;
private Integer checkDay;
private Integer warnPercent;
private String warnContent;
/** default constructor */
public Traffic() {
}
/** full constructor */
public Traffic(Integer policyId, Integer checkDay, Integer warnPercent, String warnContent) {
super();
this.policyId = policyId;
this.checkDay = checkDay;
this.warnPercent = warnPercent;
this.warnContent = warnContent;
}

五.�0�2自定义的 AutoArrayList
public class AutoArrayList extends ArrayList implements Serializable {
private static final long serialVersionUID = 1L;
private Class itemClass;
public AutoArrayList(Class itemClass){
this.itemClass = itemClass;
}
public Object get(int index){
try {
while(index >= size()){
add(itemClass.newInstance());
}
} catch (Exception e) {
e.printStackTrace();
}
return super.get(index);
}
}

六.AddTraPolicyAction
TrafficForm trafficForm = (TrafficForm)form;
List traffics = trafficForm.getTraffics();
System.out.println("traffics.size():"+traffics.size());
for (int i = 0; i < traffics.size(); i++) {
Traffic traffic = (Traffic) traffics.get(i);
System.out.println("Traffic["+i+"]CheckDay:"+traffic.getcheckDay()+" WarnPercent:"+traffic.getWarnPercent()+" WarnContent:"+traffic.getWarnContent());
}
// Integer checkDay = trafficForm.getcheckDay();
// Integer warnPercent = trafficForm.getWarnPercent();
// String warnContent = trafficForm.getWarnContent();
// System.out.println("checkDay:"+checkDay);
// System.out.println("warnPercent:"+warnPercent);
// System.out.println("warnContent:"+warnContent);
//
// String[] days = request.getParameterValues("day");
// String[] pers = request.getParameterValues("per");
// String[] contents = request.getParameterValues("content");
// System.out.println("测试day数组元素个数"+days.length);
// System.out.println("测试pers数组元素个数"+pers.length);
// System.out.println("测试contents数组元素个数"+contents.length);
// while(request.getParameterNames().hasMoreElements()){
// String day=(String)request.getParameterNames().nextElement();
// String value=request.getParameter(day);
// System.out.println("测试name:"+day+",它的值是:"+value);
// }
在action中测试，试过traffics的size总是1，总是只能获取表格中的第一行数据。也试过request.getParameterValues依然取不到其他行的数据，求解哪里有问题呢？附上我参考的页面
