struts1.2 + spring2.5 + hibernate3.2框架搭建三之后台代码_struts1.2 + spring2.5 + hibernate3.2框架demo-优快云博客

本文介绍了一个基于Struts2框架的登录模块实现方案。主要包括LoginForm表单类、LoginAction控制器类、ILoginService接口及其实现类LoginServiceImpl、LoginDAO接口及其实现类LoginDaoImpl。这些组件协同工作实现了用户的登录验证功能。

LoginForm.java代码：

package com.xy6.form;

import org.apache.struts.action.ActionForm;

public class LoginForm extends ActionForm{

	private Integer id;
	private String username;
	private String password;

	public Integer getId() {
		return id;
	}
	public void setId(Integer id) {
		this.id = id;
	}
	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;
	}

	public void reset(){
		this.id = 0;
		this.username = "";
		this.password = "";
	}

}

LoginAction.java代码：

package com.xy6.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.springframework.beans.factory.annotation.Autowired;

import com.xy6.form.LoginForm;
import com.xy6.service.ILoginService;

public class LoginAction extends Action{

	/*
	 * 在action中注入service接口，
	 * 省去在spring中配置文件中配置action的属性
	 */
	@Autowired
	private ILoginService loginService;

	@Override
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws Exception {

		LoginForm loginForm = (LoginForm)form;
		ActionForward forward = new ActionForward();

		String username = loginForm.getUsername();
		String password = loginForm.getPassword();
		// 验证用户名、密码，如果通过，跳转到success页面，
		// 否则跳转到failure页面
		if(username == null && password == null){
			forward = mapping.findForward("login");
		} else{
			if(loginService.login(username, password)){
				forward = mapping.findForward("success");
			} else{
				forward = mapping.findForward("failure");
			}
		}

		return forward;
	}

}

ILoginService.java代码：

package com.xy6.service;

public interface ILoginService {

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

LoginServiceImpl.java代码：

package com.xy6.service.impl;

import org.springframework.beans.factory.annotation.Autowired;

import com.xy6.dao.LoginDAO;
import com.xy6.service.ILoginService;

public class LoginServiceImpl implements ILoginService{

	@Autowired
	private LoginDAO loginDAO;

	public boolean login(String username, String password){
		return loginDAO.login(username, password);
	}
}

LoginDAO.java代码：

package com.xy6.dao;

public interface LoginDAO {

	public boolean login(String username, String password);

}

LoginDaoImpl.java代码：

package com.xy6.dao.impl;

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.xy6.dao.LoginDAO;

public class LoginDaoImpl extends HibernateDaoSupport implements LoginDAO {

	/*
	 * 查询用户名-密码在数据库中是否存在
	 */
	public boolean login(String username, String password){
		try{
			String hql = "from LoginForm as p where p.username = ? and p.password = ?";
			List list = this.getHibernateTemplate().find(hql,new Object[]{username,password});
			if(list != null && list.size() > 0){
				return true;
			}
		} catch(Exception ex){
			ex.printStackTrace();
		}
		return false;
	}
}

注：LoginDaoImpl sql中from后跟不一定为表名，此处应写表对于的实体类名。在该demo中表userinfo对于LoginForm类。
