struts2 list 迭代输出 到页面后 在页面修改其中的一些值 再提交到 后台 如何得到修改后的list...

转至csdn问答区
页面初始化的action将peopleList存放到session作用域中，页面文本框的name为ages,点击保存时，ages的值字段会字段封装到String[] ages数组。

保存的action代码可以参考如下代码：
Java code
public class InitAction extends ActionSupport implements ServletRequestAware
{
private HttpServletRequest request;
private String[] ages;

public void setAges(String[] ages){
this.ages=ages;
}

public String[] getAges(){
return ages;
}

public String exceute(){
//从session中取出peopleList
HttpSession session = request.getSession();
List peopleList = (List)session.getAttribute("peopleList");

for(int i=0;i<peopleList.size();i++){
People people = (People)peopleList.get(i);
people.setAge(Integer.valueOf(ages[i]));//赋值
}

//peopleList就为修改后的List
return SUCCESS;
}



public HttpServletRequest getRequest() {
return request;
}

public void setServletRequest(HttpServletRequest request) {
this.request = request;
