ASP.NET交通信息网上查询系统的设计与实现(源代码+论文+开题报告) 随着国内经济的不断发展，交通条件的发展呈现出无法比拟的优势：数量上的海量化、繁多的种类、分布开放、时效性、高增值性等。通过互联网查询的资料来看，国内目前类似的系统比较多的是公交查询系统，而城际之间的交通查询系统并不过见，较多的仍然是以时刻表为基础的查询系统，其缺点在于不能根据特定条件进行检索，转乘查询也不支持，由于交通工具单一，一个系统只支持火车或飞机，加之服务与成本意识较为薄弱，使城际间的交通信息查询常常给旅客带来困绕。数据库的保护功能：数据库中的数据是信息社会的战略资源，对数据的保护是至关重要的大事。阅读详情

题目：火车车次信息管理

一、语言和环境

A、实现语言

Java

B、环境要求

JDK1.7、Eclipse、Tomcat7.*、mysql

二、功能要求

使用JSP+Servlet实现火车车次信息管理功能，mysql作为后台数据库，功能包括车次信息浏览、火车车次信息详情和车次信息删除两大功能。具体要求如下：

（1）打开火车车次信息管理首页，以列表方式显示所有车次信息，页面列表要求实现隔行变色效果，如图-1所示。

图-1

(2)单击“删除”链接可以进行火车车次信息删除，如果没有复选框被选中，当单击“删除”链接时需要提示“请选择车次！”信息，如图-2所示。

图-2

（3）如果选中复选框，单击“删除”链接，执行删除车次信息操作，并根据删除结果给出相应的信息提示，如图-3所示。

图-3

点击确定后，跳转至车次信息列表页面，并显示更新后的车次列表信息，如图-4所示。

图-4

（4）单击车次超链接，则跳转至指定车次的火车车次详情页面，如图-5所示。

三、

数据库设计

数据库表名称及要求：

表名	train_info		中文表名称	火车车次信息表
主键	train_no
序号	字段名称	字段说明	类型	长度	属性	备注
1	train_no	车次编号	varchar	50	主键
2	start_station	始发站	varchar	50	非空
3	arrival_station	终点站	varchar	50	非空
4	start_time	出发时间	varchar	50	非空
5	arrival_time	到达时间	varchar	50	非空
6	type	车次类型	varchar	50	非空
7	runtime	运行时间	varchar	50	非空
8	mile	里程	double(18, 1)		非空

创建实体类

package com.qf.entity;

public class TrainInfo {
	private String train_no;
	private String start_station;
	private String arrival_station;
	private String start_time;
	private String arrival_time;
	private String type;
	private String runtime;
	private double mile;
	public String getTrain_no() {
		return train_no;
	}
	public void setTrain_no(String train_no) {
		this.train_no = train_no;
	}
	public String getStart_station() {
		return start_station;
	}
	public void setStart_station(String start_station) {
		this.start_station = start_station;
	}
	public String getArrival_station() {
		return arrival_station;
	}
	public void setArrival_station(String arrival_station) {
		this.arrival_station = arrival_station;
	}
	public String getStart_time() {
		return start_time;
	}
	public void setStart_time(String start_time) {
		this.start_time = start_time;
	}
	public String getArrival_time() {
		return arrival_time;
	}
	public void setArrival_time(String arrival_time) {
		this.arrival_time = arrival_time;
	}
	public String getType() {
		return type;
	}
	public void setType(String type) {
		this.type = type;
	}
	public String getRuntime() {
		return runtime;
	}
	public void setRuntime(String runtime) {
		this.runtime = runtime;
	}
	public double getMile() {
		return mile;
	}
	public void setMile(double mile) {
		this.mile = mile;
	}
	
}

创建jdbc类对数据库的表进行操作

package com.qf.tools;


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

public class DBUtils {
	
	public static Connection conn=null;
	public static PreparedStatement state=null;
	public static ResultSet rs=null;
	
	public static Connection getConnection() throws ClassNotFoundException, SQLException {
		Class.forName("com.mysql.jdbc.Driver");
		conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/lianxi", "root", "147258");
		return conn;
	}
	
	public static int update(String sql,Object...obs) {
		int result=0;
		try {
			DBUtils.getConnection();
			state=conn.prepareStatement(sql);
			for (int i = 0; i < obs.length; i++) {
				state.setObject(i+1, obs[i]);
			}
			result=state.executeUpdate();
		} catch (Exception e) {
			e.printStackTrace();
		}
		return result;
	}
	
	public static ResultSet query(String sql,Object...obs) {
		try {
			DBUtils.getConnection();
			state=conn.prepareStatement(sql);
			for (int i = 0; i < obs.length; i++) {
				state.setObject(i+1, obs[i]);
			}
			rs=state.executeQuery();
		}catch (Exception e) {
			e.printStackTrace();
		}
		return rs;
	}
	
	public static void closeObject() {
		try {
			if(rs!=null) {
				rs.close();
			}
			if(state!=null) {
				state.close();
			}
			if(conn!=null) {
				conn.close();
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
	
}

创建DAO类对数据库的表进行增删改查操作

package com.qf.dao;

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

import com.qf.entity.TrainInfo;
import com.qf.tools.DBUtils;

public class TrainInfoDAO {

	public List<TrainInfo> queryAllTrainInfo() {
		List<TrainInfo> trains=new ArrayList<TrainInfo>();
		try {
			String sql="select train_no,start_station,arrival_station,start_time,arrival_time,type,runtime,mile from train_info order by start_time";
			DBUtils.rs=DBUtils.query(sql);
			while(DBUtils.rs.next()) {
				TrainInfo t=new TrainInfo();
				t.setTrain_no(DBUtils.rs.getString("train_no"));
				t.setStart_station(DBUtils.rs.getString("start_station"));
				t.setArrival_station(DBUtils.rs.getString("arrival_station"));
				t.setStart_time(DBUtils.rs.getString("start_time"));
				t.setArrival_time(DBUtils.rs.getString("arrival_time"));
				t.setType(DBUtils.rs.getString("type"));
				t.setRuntime(DBUtils.rs.getString("runtime"));
				t.setMile(DBUtils.rs.getDouble("mile"));
				trains.add(t);
			}
		} catch (SQLException e) {
			e.printStackTrace();
		} finally {
			DBUtils.closeObject();
		}
		return trains;
	}

	public void deleteTrainInfo(String[] trains) {
		String sql="delete from train_info where train_no=?";
		for (int i = 0; i < trains.length; i++) {
			DBUtils.update(sql, trains[i]);
		}
		DBUtils.closeObject();
	}

	public TrainInfo queryTrainInfo(String train_no) {
		TrainInfo t=null;
		try {
			String sql="select train_no,start_station,arrival_station,start_time,arrival_time,type,runtime,mile from train_info where train_no=?";
			DBUtils.rs=DBUtils.query(sql,train_no);
			while(DBUtils.rs.next()) {
				t=new TrainInfo();
				t.setTrain_no(DBUtils.rs.getString("train_no"));
				t.setStart_station(DBUtils.rs.getString("start_station"));
				t.setArrival_station(DBUtils.rs.getString("arrival_station"));
				t.setStart_time(DBUtils.rs.getString("start_time"));
				t.setArrival_time(DBUtils.rs.getString("arrival_time"));
				t.setType(DBUtils.rs.getString("type"));
				t.setRuntime(DBUtils.rs.getString("runtime"));
				t.setMile(DBUtils.rs.getDouble("mile"));
			}
		} catch (SQLException e) {
			e.printStackTrace();
		} finally {
			DBUtils.closeObject();
