任务5
【任务5.3】创建基础匹配实体类
在com.qst.dms.entity下创建MatchedDataBase.java
该类中暂时不用定义任何方法
程序设计
package com.qst.dms.entity; public class MatchedDataBase { }
【任务5.3.1】日志数据匹配类，对日志实体数据进行匹配，对同一个用户在同一个IP地址登录登出信息进行匹配。
在com.qst.dms.entity 下创建MatchedLogRec.java，继承MatchedDataBase类
功能要求：
- 成员属性及相关方法如下
private LogRec login; private LogRec logout; // user用户登录名 public String getUser() { return login.getUser(); } // 登入时刻 public Date getLogInTime() { return login.getTime(); } // 登出时刻 public Date getLogoutTime() { return logout.getTime(); } // 登入记录 public LogRec getLogin() { return login; } // 登出记录 public LogRec getLogout() { return logout; } public MatchedLogRec() { } public MatchedLogRec(LogRec login, LogRec logout) { }
- 构造方法
toString()： login.toString() + " | " + logout.toString()
程序设计
package com.qst.dms.entity; import java.util.Date; public class MatchedLogRec extends MatchedDataBase { private LogRec login; private LogRec logout; // user用户登录名 public String getUser() { return login.getUser(); } // 登入时刻 public Date getLogInTime() { return login.getTime(); } // 登出时刻 public Date getLogoutTime() { return logout.getTime(); } // 登入记录 public LogRec getLogin() { return login; } // 登出记录 public LogRec getLogout() { return logout; } public MatchedLogRec() { } public MatchedLogRec(LogRec login, LogRec logout) { this.login = login; this.logout = logout; } @Override public String toString() { return login.toString() + " | " + logout.toString(); } }
【任务5.3.2】修改LogRecService类，在该类中增加显示匹配日志信息的showMatchLog方法。
// 匹配日志信息输出 public void showMatchLog(MatchedLogRec... matchLogs) { …… }
程序设计
package com.qst.dms.service; import com.qst.dms.entity.LogRec; import com.qst.dms.entity.MatchedLogRec; 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); } } // 匹配日志信息输出 public void showMatchLog(MatchedLogRec... matchLogs) { System.out.println("匹配日志信息："); for (MatchedLogRec matchLog : matchLogs) { System.out.println(matchLog); } } }
【任务5.4.1】物流数据匹配类，对物流实体数据进行匹配，对发货、送货、签收物流信息进行匹配。
在com.qst.dms.entity 下创建MatchedTransport.java，继承MatchedDataBase类
功能要求：
- 成员属性及相关方法如下
private Transport send; private Transport trans; private Transport receive; public Transport getSend() { return send; } public void setSend(Transport send) { this.send = send; } public Transport getTrans() { return trans; } public void setTrans(Transport trans) { this.trans = trans; } public Transport getReceive() { return receive; } public void setReceive(Transport receive) { this.receive = receive;
- 构造方法
toString()： send.toString()+"|"+trans.toString()+"|"+receive;
程序设计
package com.qst.dms.entity; public class MatchedTransport extends MatchedDataBase { private Transport send; private Transport trans; private Transport receive; public MatchedTransport(Transport send, Transport tran, Transport rec) { this.send=send; this.trans=tran; this.receive=rec; } public MatchedTransport() { } public Transport getSend() { return send; } public void setSend(Transport send) { this.send = send; } public Transport getTrans() { return trans; } public void setTrans(Transport trans) { this.trans = trans; } public Transport getReceive() { return receive; } public void setReceive(Transport receive) { this.receive = receive; } @Override public String toString() { return send.toString() + " | " + trans.toString() + " | " + receive.toString(); } }
【任务5.4.2】修改TransportService类，在该类中增加显示匹配日志信息的showMatchTransport方法。
// 匹配的物流信息输出 public void showMatchTransport(MatchedTransport... matchTrans) {
程序设计
package com.qst.dms.service; import com.qst.dms.entity.MatchedLogRec; import com.qst.dms.entity.MatchedTransport; import com.qst.dms.entity.Transport; import java.util.Date; import java.util.Scanner; public class TransportService { private Scanner scanner; public TransportService() { scanner = new Scanner(System.in); } public Transport inputTransport() { 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 = Transport.GATHER; System.out.println("请输入货物经手人："); String handler = scanner.next(); System.out.println("请输入收货人："); String reciver = scanner.next(); int transportType; while (true) { try { System.out.println("请输入物流状态（1表示发货中，2表示送货中，3表示已签收）："); transportType = scanner.nextInt(); if (transportType ==1 || transportType == 2 || transportType==3) { break; } else { throw new IllegalArgumentException("非法的物流状态"); } } catch (Exception e) { System.out.println("输入错误，请重新输入"); scanner.nextLine(); } } return new Transport(id, nowDate, address, type, handler, reciver, transportType); } public void showTransport(Transport... transports) { System.out.println("物流信息："); for (Transport transport : transports) { System.out.println(transport); } } // 匹配物流信息输出 public void showMatchTransport(MatchedTransport... matchTrans) { System.out.println("匹配物流信息："); for (MatchedTransport matchTran : matchTrans) { System.out.println(matchTran); } } }
