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

package com.qst.dms.entity;import java.util.Date;public class LogRec {// 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 MATCH = 2;// "匹配";public static final int RECORD = 3;// "记录";public static final int SEND = 4;// "发送";public static final int RECEIVE = 5;// "接收";public static final int WRITE = 6;// "归档";public static final int SAVE = 7;// "保存";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) {this.time = 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;}@Overridepublic String toString() {return "LogRec:" +"\nid=" + id +"\ntime=" + time +"\naddress='" + address +"\ntype=" + type +"\nuser='" + user +"\nip='" + ip +"\nlogType=" + LogTypeArray[logType] +"\n";}public String[] toArray() {String[] arr = new String[7];arr[0] = String.valueOf(id);arr[1] = String.valueOf(time);arr[2] = address;arr[3] = String.valueOf(type);arr[4] = user;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IPSystem.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。
