使用Struts2中的标签来显示集合中的数据时非常常见的应用，之前对于两种显示方式总有些糊里糊涂的今天做了个比较并且写了个例子来验证。
1.Action中的代码
public class AjaxLoginAction extends ActionSupport {
private String result;
private String loginName;
private String password;
List<User> list;
public List<User> getList() {
return list;
}
public void setList(List<User> list) {
this.list = list;
}
public String getResult() {
return result;
}
public void setResult(String result) {
this.result = result;
}
public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
public String execute() {
try{
User user1=new User();
user1.setUserName("张三");
user1.setPassword("123");
user1.setAge("22");
User user2=new User();
user2.setUserName("李四");
user2.setPassword("456");
user2.setAge("23");
this.list=new ArrayList<User>();
this.list.add(user1);
this.list.add(user2);
}catch(Exception e){
System.out.println(e);
}
return "success";
}
}
