Action 處理請求引數-屬性驅動模型驅動

1.屬性驅動

User.java

package com.qwl.domain;

public class User {
	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;
	}
}

UserLogin.java

package com.qwl.action;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.qwl.domain.User;

public class UserLoginAction extends ActionSupport {
	private User user;

	public User getUser() {
		return user;
	}

	public void setUser(User user) {
		this.user = user;
	}
	
	public String excute() throws Exception{
		ActionContext context =ActionContext.getContext();
		if("itcast".equals(user.getUsername())&&"123".equals(user.getPassword())){
			context.getSession().put("username", user.getUsername());
			context.getSession().put("password", user.getPassword());
			return SUCCESS;
		}else{
			context.getSession().put("error", "使用者登入失敗");
			return ERROR;
		}
	}
}
