WebWork2.2.4模拟webwork+hibernate的模板例子

包结构:
com.huanglq.action    --------LoginAction.java 
com.huanglq.dao          --------LoginDao..java,LoginDaoImpl.java
com.huanglq.vo            --------User.java
----------------------------------------------------
vo:(model)
User.java

package com.huanglq.vo;

public class User {

	private String username;

	private String password;

	public String getPassword() {
		return password;
	}

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

	public String getUsername() {
		return username;
	}

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

}

-----------------
dao:(数据库访问层)
UserDao.java

package com.huanglq.dao;

import com.huanglq.vo.User;

public interface UserDao {

	public User login(String username, String password);
}

-----------------
UserDaoImpl.java

package com.huanglq.dao;

import com.huanglq.vo.User;

public class UserDaoImpl implements UserDao {

	// 判断用户是否存在,不存在则为null
	// 这里可以集成Hibernate来实现,当然也可以用上Spring
	public User login(String username, String password) {
		User user = null;
		// 如果是Hibernate的话,这里的操作就是找User是否存在
		// 这里只是个模板
		if ("kyo".equalsIgnoreCase(username)&& "123".equalsIgnoreCase(password)) {
			user = new User();
			user.setUsername(username);
			user.setPassword(password);

		}
		return user;
	}

}

--------------------
action(逻辑判断)
LoginAction.java

package com.huanglq.action;

import com.huanglq.dao.UserDao;
import com.huanglq.dao.UserDaoImpl;
import com.huanglq.vo.User;
import com.opensymphony.xwork.Action;
import com.opensymphony.xwork.ModelDriven;

public class LoginAction implements Action, ModelDriven {

	private User user = new User();

	public User getUser() {
		return user;
	}

	public void setUser(User user) {
		this.user = user;
	}

	// 这里是实现Action中的方法,当然页可以空实现,在form中 *.action (*是action名)
	public String execute() throws Exception {
		UserDao userDao = new UserDaoImpl();
		try {
			user = userDao.login(user.getUsername(), user.getPassword());
		} catch (Exception e) {
			user = null;
		}
		if (user != null) {
			return "success";
		} else {
			return "error";
		}
	}

	public Object getModel() {
		// 这里要返回一个model对象
		return user;
	}

	// 自己的方法,在form中 *!login.action (*是action名)
	public String login() {
		UserDao userDao = new UserDaoImpl();
		try {
			user = userDao.login(user.getUsername(), user.getPassword());
		} catch (Exception e) {
			user = null;
		}
		if (user != null) {
			return "success";
		} else {
			return "error";
		}
	}

}
