我的第一个Struts程序

1、程序结构

2、各种文件

LoginAction.java

package com.tfj.action;

public class LoginAction {
    private String username;
    private String password;

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String execute() {
        if (username.equals("tufujie")&&password.equals("123")) {
            return "success";
        } else
            return "error";
    }
}
