Struts2框架写员工管理系统

一、概述

这是基于Struts2框架写的一个员工管理系统，可以进行员工的增删改查操作，还有登录功能。

二、实现

话不多说，先来几个运行界面，下面上代码：
用户登录：

注册，也就是新增员工信息，这里写的直接新增员工信息后，员工可以直接登录，你可以改成单独分一个管理人员登录表：

登录成功之后，员工信息列表：

然后进行修改操作，修改页面和注册页面一样，但是会根据你要修改的id自动填充信息，删除就是直接删除。

上代码：
1、目录结构：

2、LoginAction.java

package com.hnpi.action;

					// 登录成功 保留登录信息
					Map session = ActionContext.getContext().getSession();
					session.put("user", username);

5、UserDaoImpl.java

package com.hnpi.dao.impl;

import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

}

6、UserDao.java

package com.hnpi.dao;

import java.util.List;
import com.hnpi.bean.User;

public interface UserDao {
	/**
	 * 查询用户列表
	 * 
	 * @return
	 */
	public List selectAllUser();

	/**
	 * 新增用户
	 * 
	 * @param user
	 * @return
	 */
	boolean addUser(User user);

	/**
	 * 根据id查询员工信息
	 * 
	 * @param id
	 * @return
	 */
	public User selectUserById(int id);

	/**
	 * 更新员工信息
	 * 
	 * @return
	 */
	public boolean updateUser(User user);

	/**
	 * 删除员工信息
	 * 
	 * @param id
	 * @return
	 */
	boolean delUser(int id);
}

7、UserInterceptor.java 这个是拦截器。这里可以不用也可以用，用的话需要在struts.xml文件里面配置拦截器。

package com.hnpi.interceptor;

import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionInvocation;
import com.opensymphony.xwork2.interceptor.AbstractInterceptor;

public class UserInterceptor extends AbstractInterceptor{

	@Override
	public String intercept(ActionInvocation invocation) throws Exception {
		String user=(String) ActionContext.getContext().getSession().get("user");
        if (user==null||"".equals(user)) {
            return "fail";
        }
        return invocation.invoke();
	}
	

}

8、UserServiceImpl.java

package com.hnpi.service.impl;

import java.util.List;

import com.hnpi.bean.User;
import com.hnpi.dao.UserDao;
import com.hnpi.dao.impl.UserDaoImpl;
import com.hnpi.service.UserService;

public class UserServiceImpl implements UserService {

	/**
	 * 调用Dao层实现查询
	 */
	public List selectAllUser() {
		UserDao userDao = new UserDaoImpl();
		List users = userDao.selectAllUser();
		return users;
	}

	/**
	 * 调用Dao层实现新增
	 */
	public boolean addUser(User user) {
		UserDao userDao = new UserDaoImpl();
		return userDao.addUser(user);
	}

	/**
	 * 调用Dao层实现根据id查询
	 */
	public User selectUserById(int id) {
		UserDao userDao = new UserDaoImpl();
		return userDao.selectUserById(id);
	}

	/**
	 * 调用Dao层实现更新
	 */
	public boolean updateUser(User user) {
		UserDao userDao = new UserDaoImpl();
		return userDao.updateUser(user);
	}

	/**
	 * 调用Dao层实现删除
	 */
	public boolean delUser(int id) {
		UserDao userDao = new UserDaoImpl();
		return userDao.delUser(id);
	}

}

9、UserService.java

package com.hnpi.service;

import java.util.List;

import com.hnpi.bean.User;

public interface UserService {

	/**
	 * 查找用户列表
	 * @return
	 */
	public List selectAllUser();
	
	/**
	 * 新增用户
	 * 
	 * @param user
	 * @return
	 */
	boolean addUser(User user);
	
	/**
	 * 根据id查询员工信息
	 * @param id
	 * @return
	 */
	public User selectUserById(int id);
	
	/**
	 * 更新员工信息
	 * 
	 * @return
	 */
	public boolean updateUser(User user);
	
	/**
	 * 删除员工信息
	 * 
	 * @param id
	 * @return
	 */
	boolean delUser(int id);
}

10、DBUtil.java 这是链接数据库的 要配置成你自己的数据库

package com.hnpi.util;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;

public class DBUtil {
	/**
	 * 连接数据库
	 * @return
	 */
	public static Connection getConn(){
		String url = "jdbc:mysql://localhost:3308/staff?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false&serverTimezone=UTC";
		String user = "root";
		String pwd = "root";
		Connection conn = null;
		
		try {
			Class.forName("com.mysql.jdbc.Driver");
			conn = DriverManager.getConnection(url, user, pwd);
		} catch (SQLException e) {
			e.printStackTrace();
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		}
		return conn;						
	}
	/**
	 * 关闭数据库
	 * @param conn
	 * @param ps
	 * @param rs
	 */
	public static void closeConn(Connection conn,PreparedStatement ps,ResultSet rs){
		try{
			if(conn!=null){
				conn.close();
			}
			if(ps!=null){
				ps.close();
			}
			if(rs!=null){
				rs.close();
			}
		}catch(SQLException e){
			e.printStackTrace();
		}
	}
}
