利用Java的面向对象进阶知识，结合日志，创建一个简单电影院系统
一.定义一个User作为父类，减少代码冗余
public class User {
//用户类，充当父类
private String loginName; //假名（昵称），不重复
private String username; //真名
private String passWord;
private String sex;
private String phone;
private double money;
public User() {
}
public User(String loginName, String username, String passWord, String sex, String phone) {
this.loginName = loginName;
this.username = username;
this.passWord = passWord;
this.sex = sex;
this.phone = phone;
}
public String getLoginName() {
return loginName;
}
public void setLoginName(String loginName) {
this.loginName = loginName;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassWord() {
return passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
public String getSex() {
return sex;
}
public void setSex(String sex) {
this.sex = sex;
}
public String getPhone() {
return phone;
}
public void setPhone(String phone) {
this.phone = phone;
}
public double getMoney() {
return money;
}
public void setMoney(double money) {
this.money = money;
}
}二.定义顾客类，以及商家类
public class Business extends User {
//商家角色，独有属性
private String shopName; //店铺名称
private String address;
public String getShopName() {
return shopName;
}
public void setShopName(String shopName) {
this.shopName = shopName;
}
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
}
public class Customer extends User{
//客户角色
}三.定义一个电影类
import java.util.*;
public class Movie {
private String name;
private String actor;
private double score;
private double time;
private double price;
private int number; //余票
private Date startTime; //放映时间
public Movie() {
}
public Movie(String name, String actor, double time, double price, int number, Date startTime) {
this.name = name;
this.actor = actor;
this.score = score;
this.time = time;
this.price = price;
this.number = number;
this.startTime = startTime;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getActor() {
return actor;
}
public void setActor(String actor) {
this.actor = actor;
}
public double getScore() {
return score;
}
public void setScore(double score) {
this.score = score;
}
public double getTime() {
return time;
}
public void setTime(double time) {
this.time = time;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
public Date getStartTime() {
return startTime;
}
public void setStartTime(Date startTime) {
this.startTime = startTime;
}
}四.添加logback.xml配置文件
注意：输出日志的格式为ERROR即可,如果设置ALL，不要在控制台打印
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<!--定义日志文件的存储地址 勿在 LogBack 的配置中使用相对路径-->
<property name="LOG_HOME" value="E:/log" />
<!-- 控制台输出 -->
<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
<!-- 日志输出编码 -->

<layout class="ch.qos.logback.classic.PatternLayout">
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符-->
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
</pattern>
</layout>
</appender>
<!-- 按照每天生成日志文件 -->
<appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
<Encoding>UTF-8</Encoding>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!--日志文件输出的文件名-->

<MaxHistory>30</MaxHistory>
</rollingPolicy>
<layout class="ch.qos.logback.classic.PatternLayout">
<!--格式化输出：%d表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度%msg：日志消息，%n是换行符-->
<pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n
</pattern>
</layout>
<!--日志文件最大的大小-->
<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">

</triggeringPolicy>
</appender>
<!-- 日志输出级别 -->
<root level="ERROR">

<appender-ref ref="FILE" />
</root>
</configuration>五.测试类
