任务3

【任务3.1】实现日志实体类

在com.qst.dms.entity 下创建LogRec.java

功能要求：

成员属性如下

    // ID标识
	private int id;
	// 时间
	private Date time;
	// 地点
	private String address;
	// 状态
	private int type;
	/**
	 * 登录用户名
	 */
	private String user;
	/**
	 * 登录用户主机IP地址
	 */
	private String ip;
	/**
	 * 登录状态：登录、登出
	 */
	private int logType;
	/**
	 * 登录常量LOG_IN、登出常量LOG_OUT
	 */
	public static final int LOG_IN = 1;
	public static final int LOG_OUT = 0;

	// 状态常量（公共的静态常量）
	public static final int GATHER = 1;// "采集"
	public static final int MATHCH = 2;// "匹配";
	public static final int RECORD = 3;// "记录";
	public static final int SEND = 4;// "发送";
	public static final int RECIVE = 5;// "接收";
	public static final int WRITE = 6;// "归档";
	public static final int SAVE = 7;// "保存";

构造方法、get/set方法、toString()。
实现toArray()方法，将对象的属性数据，转换为字符数组。

程序设计

import java.util.Date;

public class LogRec {
    // ID标识
    private int id;
    // 时间
    private Date time;

    public static final String LogTypeArray[]=new String[]{
        "LogOut",
        "LogIn"
    };

    public LogRec(int id, Date time, String address, int type, String user, String ip, int logType) {
        this.id = id;
        this.time = time;
        this.address = address;
        this.type = type;
        this.user = user;
        this.ip = ip;
        this.logType = logType;
    }

    public LogRec() {
    }
    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public Date getTime() {
        return time;
    }

    public void setTime(Date time) {

    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public int getType() {
        return type;
    }

    public void setType(int type) {
        this.type = type;
    }

    public String getUser() {
        return user;
    }

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

    public String getIp() {
        return ip;
    }

    public void setIp(String ip) {
        this.ip = ip;
    }

    public int getLogType() {
        return logType;
    }

    public void setLogType(int logType) {
        this.logType = logType;
    }

    @Override

        return "LogRec:" +
                "\nid=" + id +
                "\ntime=" + time +
                "\naddress='" + address +
                "\ntype=" + type +
                "\nuser='" + user +
                "\nip='" + ip +
                "\nlogType=" + LogTypeArray[logType] +

        arr[5] = ip;
        arr[6] = String.valueOf(LogTypeArray[logType]);
        return arr;
    }

}

【任务3.2】创建日志业务类，实现日志信息的采集及打印输出

在com.qst.dms.service 下创建LogRecService.java

功能要求：

实现inputLog方法

public LogRec inputLog() {
    ……
    }

        // 提示用户输入ID标识
		System.out.println("请输入ID标识：");
		// 接收键盘输入的整数
		int id = scanner.nextInt();
		// 获取当前系统时间
		Date nowDate = new Date();
		// 提示用户输入地址
		System.out.println("请输入地址：");
		// 接收键盘输入的字符串信息
		String address = scanner.next();
		// 数据状态是“采集”
		int type = LogRec.GATHER;

		// 提示用户输入登录用户名
		System.out.println("请输入 登录用户名：");
		// 接收键盘输入的字符串信息
		String user = scanner.next();
		// 提示用户输入主机IP
		System.out.println("请输入 主机IP:");
		// 接收键盘输入的字符串信息
		String ip = scanner.next();
		// 提示用户输入登录状态、登出状态
		System.out.println("请输入登录状态:1是登录，0是登出");
		int logType = scanner.nextInt();

在inputLog方法中实现，在控制台模拟接收数据，并返回日志数据对象

实现showLog方法,可打印输出日志信息

public void showLog(LogRec... logRecs) {
 	……
 	}

程序设计

package com.qst.dms.service;

import com.qst.dms.entity.LogRec;

import java.util.Date;
import java.util.Scanner;

public class LogRecService {

    private Scanner scanner;

    public LogRecService() {
        scanner = new Scanner(System.in);
    }

    public LogRec inputLog() {
        System.out.println("请输入ID标识：");
        int id = scanner.nextInt();
        Date nowDate = new Date();
        System.out.println("请输入地址：");
        String address = scanner.next();
        int type = LogRec.GATHER;
        System.out.println("请输入登录用户名：");
        String user = scanner.next();
        System.out.println("请输入主机IP：");
        String ip = scanner.next();
        int logType;
        while (true) {
            try {
                System.out.println("请输入登录状态（1表示登录，0表示登出）：");
                logType = scanner.nextInt();
                if (logType == 0 || logType == 1) {
                    break;
                } else {
                    throw new IllegalArgumentException("非法的登录状态");
                }
            } catch (Exception e) {
                System.out.println("输入错误，请重新输入");
                scanner.nextLine();
            }
        }

        return new LogRec(id, nowDate, address, type, user, ip, logType);
    }

    public void showLog(LogRec... logRecs) {
        System.out.println("日志信息：");
        for (LogRec logRec : logRecs) {
            System.out.println(logRec);
        }
    }
}

【任务3.3】创建日志测试类，测试任务3.2中的程序，演示日志信息的采集及打印输出

在com.qst.dms.dos 下创建LogRecDemo.java

功能要求：采集2组日志信息，放到数组中，再打印输出

package com.qst.dms.dos;

import com.qst.dms.entity.LogRec;
import com.qst.dms.service.LogRecService;

public class LogRecDemo {
    public static void main(String[] args) {
        LogRecService logRecService = new LogRecService();

        // 采集日志信息
        LogRec logRec1 = logRecService.inputLog();
        LogRec logRec2 = logRecService.inputLog();

        // 放到数组中
        LogRec[] logRecArray = {logRec1, logRec2};

        // 打印输出
        logRecService.showLog(logRecArray);
    }
}

测试：
要求全部可能情况都要测一遍

存在哪些可能的bug及修复?

当登陆状态输入非0非1的其他字符时，程序会报错，应该通过异常处理当用户输入非0非1的其他字符时，提醒用户重新输入。
