注意兩個input的標籤name為“userName”、“userPsw”，則其表單處理類，此處是LoginAction類應有對應名稱的屬性以及set方法
LoginAction.java
package com.action; import com.opensymphony.xwork2.Action; /** * @author WenSe * @date 2018/10/25 13:40 */ public class LoginAction { private String userName; private String userPsw; public String login(){ System.out.println(userName + "/"+userPsw); return Action.SUCCESS; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserPsw() { return userPsw; } public void setUserPsw(String userPsw) { this.userPsw = userPsw; } }
action處理類提供get方法則頁面可通過el表示式獲取屬性值
success.jsp
